NSAIDs are known to have a relaxing effect on the ureter, but a randomized controlled trial found no difference between NSAIDs and a placebo in terms of this effect. Currently, only two classes of drugs, calcium channel blockers and alpha-blockers, are considered effective as medical expulsive therapy (MET). Calcium channel blockers work by blocking the active calcium channel pump that the smooth muscle of the ureter uses to contract, resulting in relaxation of the muscle and improved stone passage. Alpha-blockers, on the other hand, are commonly used as the first-line treatment to enhance stone passage. They reduce the basal tone of the ureter smooth muscle, decrease the frequency of peristaltic waves, and lower ureteric contraction. This leads to a decrease in intraureteric pressure below the stone, increasing the chances of stone passage. Patients treated with calcium channel blockers or alpha-blockers have been shown to have a 65% higher likelihood of spontaneous stone passage compared to those not given these medications.

Classical symptoms of a urinary tract infection (UTI) typically include dysuria, suprapubic tenderness, urgency, haematuria, increased frequency of micturition, and polyuria. The Scottish Intercollegiate Guidelines Network (SIGN) has developed comprehensive guidelines for the management of UTIs. According to these guidelines, if a patient presents with three or more classical UTI symptoms and is not pregnant, it is recommended to initiate empirical treatment with a three-day course of either trimethoprim or nitrofurantoin. For more detailed information, you can refer to the SIGN guidelines on the management of suspected bacterial urinary tract infection in adults.

For the treatment of men with lower urinary tract infection (UTI), it is recommended to offer an immediate prescription of antibiotics. However, certain factors should be taken into account. This includes considering previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria.

Before starting antibiotics, it is important to obtain a midstream urine sample from men and send it for culture and susceptibility testing. This will help determine the most appropriate choice of antibiotic.

Once the microbiological results are available, it is necessary to review the initial choice of antibiotic. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The first-choice antibiotics for men with lower UTI are trimethoprim 200 mg taken orally twice daily for 7 days, or nitrofurantoin 100 mg modified-release taken orally twice daily for 7 days if the estimated glomerular filtration rate (eGFR) is above 45 ml/minute.

If there is no improvement in lower UTI symptoms after at least 48 hours on the first-choice antibiotics, or if the first-choice is not suitable, it is important to consider alternative diagnoses and follow the recommendations in the NICE guidelines on pyelonephritis (acute): antimicrobial prescribing or prostatitis (acute): antimicrobial prescribing. The choice of antibiotic should be based on recent culture and susceptibility results.

Renal colic, also known as ureteric colic, refers to a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. This condition is commonly associated with the presence of a urinary tract stone.

The main symptoms of renal or ureteric colic include severe abdominal pain on one side, starting in the lower back or flank and radiating to the groin or genital area in men, or to the labia in women. The pain comes and goes in spasms, lasting for minutes to hours, with periods of no pain or a dull ache. Nausea, vomiting, and the presence of blood in the urine are often accompanying symptoms.

People experiencing renal or ureteric colic are usually restless and unable to find relief by lying still, which helps to distinguish this condition from peritonitis. They may have a history of previous episodes and may also present with fever and sweating if there is an associated urinary infection. Some individuals may complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and the bladder, as the stone irritates the detrusor muscle.

In terms of pain management, the first-line treatment for adults, children, and young people with suspected renal colic is a non-steroidal anti-inflammatory drug (NSAID), which can be administered through various routes. If NSAIDs are contraindicated or not providing sufficient pain relief, intravenous paracetamol can be offered as an alternative. Opioids may be considered if both NSAIDs and intravenous paracetamol are contraindicated or not effective in relieving pain. Antispasmodics should not be given to individuals with suspected renal colic.

For more detailed information, you can refer to the NICE guidelines on the assessment and management of renal and ureteric stones.

This patient is displaying symptoms and signs that are consistent with a diagnosis of acute pyelonephritis. Additionally, they are showing signs of sepsis, which indicates a more serious illness or condition. Therefore, it would be advisable to admit the patient for inpatient treatment.

According to the recommendations from the National Institute for Health and Care Excellence (NICE), patients with pyelonephritis should be admitted if it is severe or if they exhibit any signs or symptoms that suggest a more serious condition, such as sepsis. Signs of sepsis include significant tachycardia, hypotension, or breathlessness, as well as marked signs of illness like impaired level of consciousness, profuse sweating, rigors, pallor, or significantly reduced mobility. A temperature greater than 38°C or less than 36°C is also indicative of sepsis.

NICE also advises considering referral or seeking specialist advice for individuals with acute pyelonephritis if they are significantly dehydrated or unable to take oral fluids and medicines, if they are pregnant, if they have a higher risk of developing complications due to known or suspected abnormalities of the genitourinary tract or underlying diseases like diabetes mellitus or immunosuppression, or if they have recurrent episodes of urinary tract infections (UTIs).

For non-pregnant women and men, the recommended choice of antibacterial therapy is as follows: oral first-line options include cefalexin, ciprofloxacin, or co-amoxiclav (taking into account local microbial resistance data), and trimethoprim if sensitivity is known. Intravenous first-line options are amikacin, ceftriaxone, cefuroxime, ciprofloxacin, or gentamicin if the patient is severely unwell or unable to take oral treatment. Co-amoxiclav may be used if given in combination or if sensitivity is known. Antibacterials may be combined if there are concerns about susceptibility or sepsis. For intravenous second-line options, it is recommended to consult a local microbiologist.

For pregnant women, the recommended choice of antibacterial therapy is cefalexin for oral first-line treatment. If the patient is severely unwell or unable to take oral treatment, cefuroxime is the recommended intravenous first-line option.

Testicular cancer is the most common form of cancer that affects men between the ages of 20 and 34. In recent times, there have been campaigns aimed at raising awareness about the importance of self-examination for early detection. Some risk factors for this type of cancer include having undescended testes, especially if it affects both testicles, which increases the risk by ten times. Additionally, individuals who have had testicular cancer in the past have a 4% chance of developing a second cancer.

The typical presentation of testicular cancer is a painless swelling in the testicles. When examined, the swelling feels hard and is located within the testis. It cannot be illuminated when light is shone through it. Approximately 60% of cases are seminomas, which are slow-growing and usually confined to the testis at the time of diagnosis. If seminomas are diagnosed at stage 1 (confined to the testis only), the 5-year survival rate is 98%. The remaining 40% of cases are teratomas, which can grow at a faster rate and often coexist with seminomas. In cases where the tumors are of mixed type, they are treated as teratomas due to their more aggressive nature. The main treatment for testicular cancer is surgery, with the possibility of additional chemotherapy and radiotherapy.

For the treatment of women with lower urinary tract infections (UTIs) who are not pregnant, it is recommended to consider either a back-up antibiotic prescription or an immediate antibiotic prescription. This decision should take into account the severity of symptoms and the risk of developing complications, which is higher in individuals with known or suspected abnormalities of the genitourinary tract or weakened immune systems. The evidence for back-up antibiotic prescriptions is limited to non-pregnant women with lower UTIs where immediate antibiotic treatment is not deemed necessary. It is also important to consider previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria. Ultimately, the preferences of the woman regarding antibiotic use should be taken into account.

If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given, it is crucial to review the choice of antibiotic once the microbiological results are available. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The following antibiotics are recommended for non-pregnant women aged 16 years and older:

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Trimethoprim 200 mg taken orally twice daily for 3 days (if low risk of resistance*)

Second-choice (if there is no improvement in lower UTI symptoms on first-choice treatment for at least 48 hours, or if first-choice treatment is not suitable):
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Pivmecillinam 400 mg initial dose taken orally, followed by 200 mg taken orally three times daily for 3 days
– Fosfomycin 3 g single sachet dose

*The risk of resistance may be lower if the antibiotic has not been used in the past 3 months, previous urine culture suggests susceptibility (although this was not used), and in younger individuals in areas where local epidemiology data indicate low resistance rates. Conversely, the risk of resistance may be higher with recent antibiotic use and in older individuals in residential facilities.

Renal colic, also known as ureteric colic, refers to a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. This condition is commonly associated with the presence of a urinary tract stone.

The main symptoms of renal or ureteric colic include severe abdominal pain on one side, starting in the flank or loin area and radiating to the groin or testicle in men, or to the labia in women. The pain comes and goes in spasms, lasting for minutes to hours, with periods of no pain or a dull ache. Nausea, vomiting, and the presence of blood in the urine are often accompanying symptoms.

The pain experienced during renal or ureteric colic is often described as the most intense pain a person has ever felt, with many women comparing it to the pain of childbirth. Restlessness and an inability to find relief by lying still are common signs, which can help differentiate renal colic from peritonitis. Previous episodes of similar pain may also be reported by the individual. In cases where there is a concomitant urinary infection, fever and sweating may be present. Additionally, the person may complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and the bladder, as the stone irritates the detrusor muscle.

It is important to seek urgent medical attention if certain conditions are met. These include signs of systemic infection or sepsis, such as fever or sweating, or if the person is at a higher risk of acute kidney injury, such as having pre-existing chronic kidney disease, a solitary or transplanted kidney, or suspected bilateral obstructing stones. Hospital admission is also necessary if the person is dehydrated and unable to consume fluids orally due to nausea and/or vomiting. If there is uncertainty regarding the diagnosis, it is recommended to consult further resources, such as the NICE guidelines on the assessment and management of renal and ureteric stones.

For the treatment of pregnant women with lower urinary tract infections (UTIs), it is recommended to provide them with an immediate prescription for antibiotics. It is important to consider their previous urine culture and susceptibility results, as well as any prior use of antibiotics that may have contributed to the development of resistant bacteria. Before starting antibiotics, it is advised to obtain a midstream urine sample from pregnant women and send it for culture and susceptibility testing.

Once the microbiological results are available, it is necessary to review the choice of antibiotic. If the bacteria are found to be resistant, it is recommended to switch to a narrow-spectrum antibiotic whenever possible. The choice of antibiotics for pregnant women aged 12 years and over is summarized below:

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days, if the estimated glomerular filtration rate (eGFR) is above 45 ml/minute.

Second-choice (if there is no improvement in lower UTI symptoms with the first-choice antibiotic for at least 48 hours, or if the first-choice is not suitable):
– Amoxicillin 500 mg taken orally three times daily for 7 days (only if culture results are available and show susceptibility).
– Cefalexin 500 mg taken twice daily for 7 days.

For alternative second-choice antibiotics, it is recommended to consult a local microbiologist and choose the appropriate antibiotics based on the culture and sensitivity results.

The most frequent reason for sudden inability to urinate in males is an enlarged prostate.

Further Reading:

Urinary retention is the inability to completely or partially empty the bladder. It is commonly seen in elderly males with prostate enlargement and acute retention. Symptoms of acute urinary retention include the inability to void, inability to empty the bladder, overflow incontinence, and suprapubic discomfort. Chronic urinary retention, on the other hand, is typically painless but can lead to complications such as hydronephrosis and renal impairment.

There are various causes of urinary retention, including anatomical factors such as urethral stricture, bladder neck contracture, and prostate enlargement. Functional causes can include neurogenic bladder, neurological diseases like multiple sclerosis and Parkinson’s, and spinal cord injury. Certain drugs can also contribute to urinary retention, such as anticholinergics, opioids, and tricyclic antidepressants. In female patients, specific causes like organ prolapse, pelvic mass, and gravid uterus should be considered.

The pathophysiology of acute urinary retention can involve factors like increased resistance to flow, detrusor muscle dysfunction, bladder overdistension, and drugs that affect bladder tone. The primary management intervention for acute urinary retention is the insertion of a urinary catheter. If a catheter cannot be passed through the urethra, a suprapubic catheter can be inserted. Post-catheterization residual volume should be measured, and renal function should be assessed through U&Es and urine culture. Further evaluation and follow-up with a urologist are typically arranged, and additional tests like ultrasound may be performed if necessary. It is important to note that PSA testing is often deferred for at least two weeks after catheter insertion and female patients with retention should also be referred to urology for investigation.

Epididymo-orchitis refers to the inflammation of the epididymis and/or testicle. It typically presents with sudden pain, swelling, and inflammation in the affected area. This condition can also occur chronically, which means that the pain and inflammation last for more than six months.

The causes of epididymo-orchitis vary depending on the age of the patient. In men under 35 years old, the infection is usually sexually transmitted and caused by Chlamydia trachomatis or Neisseria gonorrhoeae. In men over 35 years old, the infection is usually non-sexually transmitted and occurs as a result of enteric organisms that cause urinary tract infections, with Escherichia coli being the most common. However, there can be some overlap between these groups, so it is important to obtain a thorough sexual history in all age groups.

Mumps should also be considered as a potential cause of epididymo-orchitis in the 15 to 30 age group, as mumps orchitis occurs in around 40% of post-pubertal boys with mumps.

While most cases of epididymo-orchitis are infective, non-infectious causes can also occur. These include genito-urinary surgery, vasectomy, urinary catheterization, Behcet’s disease, sarcoidosis, and drug-induced cases such as those caused by amiodarone.

Patients with epididymo-orchitis typically present with unilateral scrotal pain and swelling that develops relatively quickly. The affected testis will be tender to touch, and there is usually a palpable swelling of the epididymis that starts at the lower pole of the testis and spreads towards the upper pole. The testis itself may also be involved, and there may be redness and/or swelling of the scrotum on the affected side. Patients may experience fever and urethral discharge as well.

The most important differential diagnosis to consider is testicular torsion, which requires immediate medical attention within 6 hours of onset to save the testicle. Testicular torsion is more likely in men under the age of 20, especially if the pain is very severe and sudden. It typically presents around four hours after onset. In this case, the patient’s age, longer history of symptoms, and the presence of fever are more indicative of epididymo-orchitis.

According to NICE, the presence of certain clinical features in a child between three months and five years old may indicate a urinary tract infection (UTI). These features include vomiting, poor feeding, lethargy, irritability, abdominal pain or tenderness, and urinary frequency or dysuria. For more information on this topic, you can refer to the NICE guidelines on the assessment and initial management of fever in children under 5, as well as the NICE Clinical Knowledge Summary on the management of feverish children.

For the treatment of women with lower urinary tract infections (UTIs) who are not pregnant, it is recommended to consider either a back-up antibiotic prescription or an immediate antibiotic prescription. This decision should take into account the severity of symptoms and the risk of developing complications, which is higher in individuals with known or suspected abnormalities of the genitourinary tract or weakened immune systems. The evidence for back-up antibiotic prescriptions is limited to non-pregnant women with lower UTIs where immediate antibiotic treatment is not deemed necessary. It is also important to consider previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria. Ultimately, the preferences of the woman regarding antibiotic use should be taken into account.

If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given, it is crucial to review the choice of antibiotic once the microbiological results are available. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Trimethoprim 200 mg taken orally twice daily for 3 days (if low risk of resistance*)

Second-choice (if there is no improvement in lower UTI symptoms on first-choice treatment for at least 48 hours, or if first-choice treatment is not suitable):
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Pivmecillinam 400 mg initial dose taken orally, followed by 200 mg taken orally three times daily for 3 days
– Fosfomycin 3 g single sachet dose

*The risk of resistance may be lower if the antibiotic has not been used in the past 3 months, previous urine culture suggests susceptibility (although this was not used), and in younger individuals in areas where local epidemiology data indicate low resistance rates. Conversely, the risk of resistance may be higher with recent antibiotic use and in older individuals in residential facilities.

Acute bacterial prostatitis is a sudden inflammation of the prostate gland, which can be either focal or diffuse and is characterized by the presence of pus. The most common organisms that cause this condition include Escherichia coli, Streptococcus faecalis, Staphylococcus aureus, and Neisseria gonorrhoea. The infection usually reaches the prostate through direct extension from the posterior urethra or urinary bladder, but it can also spread through the blood or lymphatics. In some cases, the infection may originate from the rectum.

According to the National Institute for Health and Care Excellence (NICE), acute prostatitis should be suspected in men who present with a sudden onset of feverish illness, which may be accompanied by rigors, arthralgia, or myalgia. Irritative urinary symptoms like dysuria, frequency, urgency, or acute urinary retention are also common. Perineal or suprapubic pain, as well as penile pain, low back pain, pain during ejaculation, and pain during bowel movements, can occur. A rectal examination may reveal an exquisitely tender prostate. A urine dipstick test showing white blood cells and a urine culture confirming urinary infection are also indicative of acute prostatitis.

The current recommendations by NICE and the British National Formulary (BNF) for the treatment of acute prostatitis involve prescribing an oral antibiotic for a duration of 14 days, taking into consideration local antimicrobial resistance data. The first-line antibiotics recommended are Ciprofloxacin 500 mg twice daily or Ofloxacin 200 mg twice daily. If these are not suitable, Trimethoprim 200 mg twice daily can be used. Second-line options include Levofloxacin 500 mg once daily or Co-trimoxazole 960 mg twice daily, but only when there is bacteriological evidence of sensitivity and valid reasons to prefer this combination over a single antibiotic.

For more information, you can refer to the NICE Clinical Knowledge Summary on acute prostatitis.

Urinary tract stones form when the concentration of salt and minerals in the urine becomes too high. These stones can be classified into five types based on their mineral composition and how they develop.

The most common type of stone is the calcium stone, which can be further divided into calcium oxalate and calcium phosphate stones. These account for 60-80% of all urinary tract stones.

Another type is the struvite or magnesium ammonium phosphate stone, making up about 10-15% of cases. Uric acid stones, also known as urate stones, occur in 3-10% of cases.

Cystine stones are less common, accounting for less than 2% of urinary tract stones. Finally, there are drug-induced stones, which are caused by certain medications such as triamterene, protease inhibitors like indinavir sulphate, and sulfa drugs. These account for approximately 1% of cases.

By understanding the different types of urinary tract stones, healthcare professionals can better diagnose and treat patients with this condition.

This patient is displaying symptoms and signs that are consistent with a diagnosis of acute pyelonephritis. Additionally, they are showing signs of sepsis, which indicates a more serious illness or condition. Therefore, it would be advisable to admit the patient for inpatient treatment.

According to the recommendations from the National Institute for Health and Care Excellence (NICE), patients with pyelonephritis should be admitted if it is severe or if they exhibit any signs or symptoms that suggest a more serious condition, such as sepsis. Signs of sepsis include significant tachycardia, hypotension, or breathlessness, as well as marked signs of illness like impaired level of consciousness, profuse sweating, rigors, pallor, or significantly reduced mobility. A temperature greater than 38°C or less than 36°C is also indicative of sepsis.

The term renal colic is commonly used to describe a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. However, a more accurate term is ureteric colic, as the pain usually arises from a blockage in the ureter itself.

Renal or ureteric colic typically presents with a sudden onset of severe abdominal pain on one side, starting in the lower back or flank and radiating to the genital area in women or to the groin or testicle in men.

The pain usually:
– Lasts for minutes to hours and comes in spasms, with periods of no pain or a dull ache
– Is often accompanied by nausea, vomiting, and blood in the urine
– Is often described as the most intense pain a person has ever experienced (many women describe it as worse than childbirth).

People with renal or ureteric colic:
– Are restless and unable to find relief by lying still (which helps distinguish it from peritonitis)
– May have a history of previous episodes
– May have a fever and sweating if there is a urinary tract infection present
– May complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and bladder (due to irritation of the bladder muscle).

If possible, a urine dipstick test should be done to support the diagnosis and check for signs of a urinary tract infection.

Checking for blood in the urine can also support the diagnosis of renal or ureteric colic. However, the absence of blood does not rule out the diagnosis and other causes of pain should be considered.

Checking for nitrite and leukocyte esterase in the urine can indicate an infection.

Pain management:
– Non-steroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for adults, children, and young people with suspected renal colic.
– Intravenous paracetamol can be given to adults, children, and young people if NSAIDs are not suitable or not providing enough pain relief.
– Opioids may be considered if both NSAIDs and intravenous paracetamol are not suitable or not providing enough pain relief.
– Antispasmodics should not be given to adults, children, and young people with suspected renal colic.

Bladder cancer ranks as the seventh most prevalent form of cancer in the United Kingdom, with men outnumbering women by a ratio of 3 to 1. The primary factors that increase the risk of bladder cancer are advancing age and smoking. It is estimated that around 50% of bladder cancer cases are caused by smoking, which is believed to be influenced by the presence of aromatic amines and polycyclic aromatic hydrocarbons that are eliminated through the kidneys. Smokers face a 2 to 6 times higher risk of developing bladder cancer compared to non-smokers.

Additional risk factors for bladder cancer include occupational exposure to aromatic amines found in dyes, paints, solvents, leather dust, combustion products, rubber, and textiles. Radiation therapy to the pelvic region is also considered a risk factor.

In developing nations, particularly in the Middle East, schistosomiasis is responsible for approximately 80% of bladder cancer cases.

Renal colic, also known as ureteric colic, refers to a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. This condition is commonly associated with the presence of a urinary tract stone.

For the treatment of women with lower urinary tract infections (UTIs) who are not pregnant, it is recommended to consider either a back-up antibiotic prescription or an immediate antibiotic prescription. This decision should take into account the severity of symptoms and the risk of developing complications, which is higher in individuals with known or suspected abnormalities of the genitourinary tract or weakened immune systems. The evidence for back-up antibiotic prescriptions is limited to non-pregnant women with lower UTIs where immediate antibiotic treatment is not deemed necessary. It is also important to consider previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria. Ultimately, the preferences of the woman regarding antibiotic use should be taken into account.

If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given, it is crucial to review the choice of antibiotic once the microbiological results are available. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The following antibiotics are recommended for non-pregnant women aged 16 years and older:

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Trimethoprim 200 mg taken orally twice daily for 3 days (if low risk of resistance*)

Second-choice (if there is no improvement in lower UTI symptoms on first-choice treatment for at least 48 hours, or if first-choice treatment is not suitable):
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Pivmecillinam 400 mg initial dose taken orally, followed by 200 mg taken orally three times daily for 3 days
– Fosfomycin 3 g single sachet dose

*The risk of resistance may be lower if the antibiotic has not been used in the past 3 months, previous urine culture suggests susceptibility (although this was not used), and in younger individuals in areas where local epidemiology data indicate low resistance rates. Conversely, the risk of resistance may be higher with recent antibiotic use and in older individuals in residential facilities.

NICE provides the following recommendations for the treatment of non-pregnant women with lower urinary tract infections (UTIs):

1. Consider prescribing a back-up antibiotic or an immediate antibiotic for women with lower UTIs, taking into account the severity of symptoms, the risk of complications, previous urine culture results, previous antibiotic use, and the woman’s preferences.

2. If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given, review the choice of antibiotic when the microbiological results are available. Change the antibiotic according to susceptibility results if bacteria are resistant and symptoms are not improving.

3. The first-choice antibiotics for non-pregnant women aged 16 years and over are nitrofurantoin (100 mg modified-release tablets taken twice daily for 3 days) or trimethoprim (200 mg tablets taken twice daily for 3 days), if there is a low risk of resistance.

4. If there is no improvement in lower UTI symptoms after at least 48 hours on the first-choice antibiotic or if the first-choice antibiotic is not suitable, the second-choice options are nitrofurantoin (100 mg modified-release tablets taken twice daily for 3 days), pivmecillinam (400 mg initial dose followed by 200 mg three times daily for 3 days), or fosfomycin (3 g single sachet dose).

5. The risk of resistance to antibiotics may be lower if the antibiotic has not been used in the past 3 months, previous urine culture suggests susceptibility, and in younger people in areas with low resistance rates. The risk of resistance may be higher with recent antibiotic use and in older people in residential facilities.

For the treatment of pregnant women with lower urinary tract infections (UTIs), it is recommended to provide them with an immediate prescription for antibiotics. It is important to consider their previous urine culture and susceptibility results, as well as any prior use of antibiotics that may have contributed to the development of resistant bacteria. Before starting antibiotics, it is advised to obtain a midstream urine sample from pregnant women and send it for culture and susceptibility testing.

Once the microbiological results are available, it is necessary to review the choice of antibiotic. If the bacteria are found to be resistant, it is recommended to switch to a narrow-spectrum antibiotic whenever possible. The choice of antibiotics for pregnant women aged 12 years and over is summarized below:

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days, if the estimated glomerular filtration rate (eGFR) is above 45 ml/minute.

Second-choice (if there is no improvement in lower UTI symptoms with the first-choice antibiotic for at least 48 hours, or if the first-choice is not suitable):
– Amoxicillin 500 mg taken orally three times daily for 7 days (only if culture results are available and show susceptibility).
– Cefalexin 500 mg taken twice daily for 7 days.

For alternative second-choice antibiotics, it is recommended to consult a local microbiologist and choose the appropriate antibiotics based on the culture and sensitivity results.

– Amoxicillin 500 mg taken orally three times daily for 7 days (only if culture results are available and show susceptibility).
– Cefalexin 500 mg taken twice daily for 7 days.

For alternative second-choice antibiotics, it is recommended to consult a local microbiologist and choose the appropriate antibiotics based on the culture and sensitivity results.

The term renal colic is commonly used to describe a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. However, a more accurate term is ureteric colic, as the pain usually arises from a blockage in the ureter itself.

Renal or ureteric colic typically presents with a sudden onset of severe abdominal pain on one side, starting in the lower back or flank and radiating to the genital area in women or to the groin or testicle in men.

The pain usually:
– Lasts for minutes to hours and comes in spasms, with periods of no pain or a dull ache
– Is often accompanied by nausea, vomiting, and blood in the urine
– Is often described as the most intense pain a person has ever experienced (many women describe it as worse than childbirth).

People with renal or ureteric colic:
– Are restless and unable to find relief by lying still (which helps distinguish it from peritonitis)
– May have a history of previous episodes
– May have a fever and sweating if there is a urinary tract infection present
– May complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and bladder (due to irritation of the bladder muscle).

If possible, a urine dipstick test should be done to support the diagnosis and check for signs of a urinary tract infection.

Checking for blood in the urine can also support the diagnosis of renal or ureteric colic. However, the absence of blood does not rule out the diagnosis and other causes of pain should be considered.

Checking for nitrite and leukocyte esterase in the urine can indicate an infection.

Pain management:
– Non-steroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for adults, children, and young people with suspected renal colic.
– Intravenous paracetamol can be given to adults, children, and young people if NSAIDs are not suitable or not providing enough pain relief.
– Opioids may be considered if both NSAIDs and intravenous paracetamol are not suitable or not providing enough pain relief.
– Antispasmodics should not be given to adults, children, and young people with suspected renal colic.

Testicular torsion is the correct diagnosis in this case. When a patient presents with sudden, severe, and acute testicular pain, testicular torsion should be assumed until proven otherwise. There are several historical factors that support this diagnosis. These include the pain occurring suddenly, being accompanied by vomiting, happening during sleep (as half of torsions occur during sleep), a previous history of torsion in the other testis, previous episodes that have resolved recently, and a history of undescended testis.

On examination, there are certain findings that further suggest testicular torsion. The testis may be positioned high in the scrotum and too tender to touch. The opposite testis may lie horizontally (known as Angell’s sign). Pain is not relieved by elevating the testis (negative Prehn’s sign), and the cremasteric reflex may be absent.

It is important to recognize that testicular torsion is a surgical emergency that requires immediate assessment and intervention to restore blood flow. Irreversible damage can occur within six hours of onset, so prompt treatment is crucial in this patient.

This patient is displaying symptoms and signs that are consistent with a diagnosis of acute pyelonephritis. Additionally, they are showing signs of sepsis, which indicates a more serious illness or condition. Therefore, it would be advisable to admit the patient for inpatient treatment.

According to the recommendations from the National Institute for Health and Care Excellence (NICE), patients with pyelonephritis should be admitted if it is severe or if they exhibit any signs or symptoms that suggest a more serious condition, such as sepsis. Signs of sepsis include significant tachycardia, hypotension, or breathlessness, as well as marked signs of illness like impaired level of consciousness, profuse sweating, rigors, pallor, or significantly reduced mobility. A temperature greater than 38°C or less than 36°C is also indicative of sepsis.

NICE also advises considering referral or seeking specialist advice for individuals with acute pyelonephritis if they are significantly dehydrated or unable to take oral fluids and medicines, if they are pregnant, if they have a higher risk of developing complications due to known or suspected abnormalities of the genitourinary tract or underlying diseases like diabetes mellitus or immunosuppression, or if they have recurrent episodes of urinary tract infections (UTIs).

For non-pregnant women and men, the recommended choice of antibacterial therapy is as follows: oral first-line options include cefalexin, ciprofloxacin, or co-amoxiclav (taking into account local microbial resistance data), and trimethoprim if sensitivity is known. Intravenous first-line options are amikacin, ceftriaxone, cefuroxime, ciprofloxacin, or gentamicin if the patient is severely unwell or unable to take oral treatment. Co-amoxiclav may be used if given in combination or if sensitivity is known. Antibacterials may be combined if there are concerns about susceptibility or sepsis. For intravenous second-line options, it is recommended to consult a local microbiologist.

For pregnant women, the recommended choice of antibacterial therapy is cefalexin for oral first-line treatment. If the patient is severely unwell or unable to take oral treatment, cefuroxime is the recommended intravenous first-line option.

Epididymo-orchitis refers to the inflammation of the epididymis and/or testicle. It typically presents with sudden pain, swelling, and inflammation in the affected area. This condition can also occur chronically, which means that the pain and inflammation last for more than six months.

The causes of epididymo-orchitis vary depending on the age of the patient. In men under 35 years old, the infection is usually sexually transmitted and caused by Chlamydia trachomatis or Neisseria gonorrhoeae. In men over 35 years old, the infection is usually non-sexually transmitted and occurs as a result of enteric organisms that cause urinary tract infections, with Escherichia coli being the most common. However, there can be some overlap between these groups, so it is important to obtain a thorough sexual history in all age groups.

Mumps should also be considered as a potential cause of epididymo-orchitis in the 15 to 30 age group, as mumps orchitis occurs in around 40% of post-pubertal boys with mumps.

While most cases of epididymo-orchitis are infective, non-infectious causes can also occur. These include genito-urinary surgery, vasectomy, urinary catheterization, Behcet’s disease, sarcoidosis, and drug-induced cases such as those caused by amiodarone.

Patients with epididymo-orchitis typically present with unilateral scrotal pain and swelling that develops relatively quickly. The affected testis will be tender to touch, and there is usually a palpable swelling of the epididymis that starts at the lower pole of the testis and spreads towards the upper pole. The testis itself may also be involved, and there may be redness and/or swelling of the scrotum on the affected side. Patients may experience fever and urethral discharge as well.

The most important differential diagnosis to consider is testicular torsion, which requires immediate medical attention within 6 hours of onset to save the testicle. Testicular torsion is more likely in men under the age of 20, especially if the pain is very severe and sudden. It typically presents around four hours after onset. In this case, the patient’s age, longer history of symptoms, and the presence of fever are more indicative of epididymo-orchitis.

To distinguish

This is a classical history for a simple urinary tract infection. The other possible causes mentioned can also result in frank haematuria, but they would be less likely based on the given history.

Bladder cancer typically presents with additional symptoms such as an abdominal mass, weight loss, and fatigue. Nephritis is more likely to cause renal angle tenderness and some systemic upset. It is often preceded by another infection.

Tuberculosis may also have more systemic involvement, although it can present on its own. Renal stones commonly cause severe pain from the loin to the groin and renal angle tenderness.

This patient is displaying symptoms and signs that are consistent with a diagnosis of acute pyelonephritis. Additionally, she is showing signs of sepsis and is pregnant, which makes it necessary to admit her for inpatient treatment.

According to the National Institute for Health and Care Excellence (NICE), patients with pyelonephritis should be admitted if it is severe or if they exhibit any signs or symptoms that suggest a more serious illness or condition, such as sepsis. Signs of sepsis include significant tachycardia, hypotension, or breathlessness, as well as marked signs of illness like impaired level of consciousness, profuse sweating, rigors, pallor, or significantly reduced mobility. A temperature greater than 38°C or less than 36°C is also indicative of sepsis.

NICE also recommends considering referral or seeking specialist advice for individuals with acute pyelonephritis if they are significantly dehydrated or unable to take oral fluids and medicines, if they are pregnant, if they have a higher risk of developing complications due to known or suspected structural or functional abnormalities of the genitourinary tract or underlying diseases like diabetes mellitus or immunosuppression, or if they have recurrent episodes of urinary tract infections (UTIs).

For non-pregnant women and men, the recommended choice of antibacterial therapy is as follows: oral first-line options include cefalexin, ciprofloxacin, or co-amoxiclav (taking into account local microbial resistance data), and intravenous first-line options (if severely unwell or unable to take oral treatment) include amikacin, ceftriaxone, cefuroxime, ciprofloxacin, or gentamicin. Co-amoxiclav may be used if given in combination or if sensitivity is known. Antibacterials may be combined if there are concerns about susceptibility or sepsis. For intravenous second-line options, it is recommended to consult a local microbiologist.

For pregnant women, the recommended choice of antibacterial therapy is as follows: oral first-line option is cefalexin, and intravenous first-line option (if severely unwell or unable to take oral treatment) is cefuroxime. Intravenous second-line options or combining antibacterials should be considered if there are concerns about susceptibility or sepsis, and consultation with a local microbiologist is recommended.

Epididymal cysts are commonly observed in men who are over the age of 40. They often appear in multiple numbers and can be found on both sides. These cysts are typically well-defined, soft to the touch, and can be illuminated when light is passed through them. Since they develop in the epididymis, they can be felt as separate from the testis, which helps to differentiate them from hydroceles. In most cases, these cysts cause no significant issues and do not require any treatment. However, larger cysts can become bothersome and may need to be drained or surgically removed.

Based on the patient’s symptoms of suprapubic pain, increased urinary frequency, and foul-smelling urine, along with the presence of nitrites, leukocytes, and blood in the urine dipstick test, the most likely cause of her symptoms is a urinary tract infection (UTI). The most probable causative organism for UTIs is Escherichia coli.

A urinary tract infection (UTI) is an infection that occurs in any part of the urinary system, from the kidneys to the bladder. It is characterized by symptoms such as dysuria, nocturia, polyuria, urgency, incontinence, and changes in urine appearance and odor. UTIs can be classified as lower UTIs, which affect the bladder, or upper UTIs, which involve the kidneys. Recurrent UTIs can be due to relapse or re-infection, and the number of recurrences considered significant depends on age and sex. Uncomplicated UTIs occur in individuals with a normal urinary tract and kidney function, while complicated UTIs are caused by anatomical, functional, or pharmacological factors that make the infection persistent, recurrent, or resistant to treatment.

The most common cause of UTIs is Escherichia coli, accounting for 70-95% of cases. Other causative organisms include Staphylococcus saprophyticus, Proteus mirabilis, and Klebsiella species. UTIs are typically caused by bacteria from the gastrointestinal tract entering the urinary tract through the urethra. Other less common mechanisms of entry include direct spread via the bloodstream or instrumentation of the urinary tract, such as catheter insertion.

Diagnosis of UTIs involves urine dipstick testing and urine culture. A urine culture should be sent in certain circumstances, such as in male patients, pregnant patients, women aged 65 years or older, patients with persistent or unresolved symptoms, recurrent UTIs, patients with urinary catheters, and those with risk factors for resistance or complicated UTIs. Further investigations, such as cystoscopy and imaging, may be required in cases of recurrent UTIs or suspected underlying causes.

Management of UTIs includes simple analgesia, advice on adequate fluid intake, and the prescription of appropriate antibiotics. The choice of antibiotic depends on the patient’s gender and risk factors. For women, first-line antibiotics include nitrofurantoin or trimethoprim, while second-line options include nitrofurantoin (if not used as first-line), pivmecillinam, or fosfomycin. For men, trimethoprim or nitrofurantoin are the recommended antibiotics. In cases of suspected acute prostatitis, fluoroquinolone antibiotics such as ciprofloxacin or ofloxacin may be prescribed for a 4-week course.

Acute bacterial prostatitis is a sudden inflammation of the prostate gland, which can be either focal or diffuse and is characterized by the presence of pus. The most common organisms that cause this condition include Escherichia coli, Streptococcus faecalis, Staphylococcus aureus, and Neisseria gonorrhoea. The infection usually reaches the prostate through direct extension from the posterior urethra or urinary bladder, but it can also spread through the blood or lymphatics. In some cases, the infection may originate from the rectum.

According to the National Institute for Health and Care Excellence (NICE), acute prostatitis should be suspected in men who present with a sudden onset of feverish illness, which may be accompanied by rigors, arthralgia, or myalgia. Irritative urinary symptoms like dysuria, frequency, urgency, or acute urinary retention are also common. Perineal or suprapubic pain, as well as penile pain, low back pain, pain during ejaculation, and pain during bowel movements, can occur. A rectal examination may reveal an exquisitely tender prostate. A urine dipstick test showing white blood cells and a urine culture confirming urinary infection are also indicative of acute prostatitis.

The current recommendations by NICE and the British National Formulary (BNF) for the treatment of acute prostatitis involve prescribing an oral antibiotic for a duration of 14 days, taking into consideration local antimicrobial resistance data. The first-line antibiotics recommended are Ciprofloxacin 500 mg twice daily or Ofloxacin 200 mg twice daily. If these are not suitable, Trimethoprim 200 mg twice daily can be used. Second-line options include Levofloxacin 500 mg once daily or Co-trimoxazole 960 mg twice daily, but only when there is bacteriological evidence of sensitivity and valid reasons to prefer this combination over a single antibiotic.

For more information, you can refer to the NICE Clinical Knowledge Summary on acute prostatitis.

There are several known risk factors for developing urinary tract stones. These include anatomical abnormalities in the renal system, such as a horseshoe kidney or ureteral stricture. Having a family history of renal stones, hypertension, gout, or hyperparathyroidism can also increase the risk. Immobilization, relative dehydration, and certain metabolic disorders that increase solute excretion, like chronic metabolic acidosis or hypercalciuria, are also risk factors. Additionally, a deficiency of citrate in the urine, cystinuria (a genetic aminoaciduria), and the use of certain drugs like diuretics or calcium/vitamin D supplements can contribute to stone formation. Residence in hot and dry climates and belonging to a higher socio-economic class have also been associated with an increased risk.

When treating men for uncomplicated urinary tract infections (UTIs), a 7-day course of antibiotics is typically recommended. Unlike women, men are advised to take a longer course of antibiotics, with a preference for 7 days instead of 3. The National Institute for Health and Care Excellence (NICE) suggests the following as the first-line treatment, although local microbiology departments may make adjustments based on antibiotic resistance patterns: Trimethoprim 200 mg taken twice daily for 7 days, or Nitrofurantoin 100 mg (modified-release) taken twice daily for 7 days. If prostatitis is suspected, a quinolone antibiotic like ciprofloxacin may be used, and treatment duration is usually 2-4 weeks.

NSAIDs are known to have a relaxing effect on the ureter, but a randomized controlled trial found no difference between NSAIDs and a placebo in terms of this effect. Currently, only two classes of drugs, calcium channel blockers and alpha-blockers, are considered effective as medical expulsive therapy (MET). Calcium channel blockers work by blocking the active calcium channel pump that the smooth muscle of the ureter uses to contract, resulting in relaxation of the muscle and improved stone passage. Alpha-blockers, on the other hand, are commonly used as the first-line treatment to enhance stone passage. They reduce the basal tone of the ureter smooth muscle, decrease the frequency of peristaltic waves, and lower ureteric contraction. This leads to a decrease in intraureteric pressure below the stone, increasing the chances of stone passage. Patients treated with calcium channel blockers or alpha-blockers have been shown to have a 65% higher likelihood of spontaneous stone passage compared to those not given these medications.

Bladder cancer is the most likely diagnosis considering the patient’s history of smoking and working in a rubber factory, as these are well-known risk factors for developing this condition. It affects approximately 1 in 5000 people and is more common in men, with a threefold higher incidence compared to women. Transitional cell carcinomas account for 90% of bladder cancer cases.

The risk factors for bladder cancer include smoking, which is responsible for 50% of male and 25% of female cases. Exposure to aromatic amine, such as working in rubber, leather, or textile factories, is also a known risk factor. Other factors include urinary stasis and schistosomiasis.

Bladder cancer can present with either visible or microscopic blood in the urine (haematuria). It may be painless or accompanied by pelvic or loin pain, as well as symptoms of recurrent urinary tract infections. A midstream urine sample (MSU) can be helpful in ruling out a urinary tract infection and detecting microscopic haematuria.

If bladder cancer is suspected, it is important to refer the patient urgently. Diagnosis is typically confirmed through biopsies taken during cystoscopy. At the time of diagnosis, 80% of tumours are confined to the mucosa or submucosa (stage T1). Treatment involves transurethral resection of the tumour (TURBT) with intravesical chemotherapy. The prognosis at this stage is excellent, with most patients dying from other causes.

Urinary tract stones form when the concentration of salt and minerals in the urine becomes too high. These stones can be classified into five types based on their mineral composition and how they develop.

The most common type of stone is the calcium stone, which can be further divided into calcium oxalate and calcium phosphate stones. These account for 60-80% of all urinary tract stones.

Another type is the struvite or magnesium ammonium phosphate stone, making up about 10-15% of cases. Uric acid stones, also known as urate stones, occur in 3-10% of cases.

Cystine stones are less common, accounting for less than 2% of urinary tract stones. Finally, there are drug-induced stones, which are caused by certain medications such as triamterene, protease inhibitors like indinavir sulphate, and sulfa drugs. These account for approximately 1% of cases.

By understanding the different types of urinary tract stones, healthcare professionals can better diagnose and treat patients with this condition.

For the treatment of women with lower urinary tract infections (UTIs) who are not pregnant, it is recommended to consider either a back-up antibiotic prescription or an immediate antibiotic prescription. This decision should take into account the severity of symptoms and the risk of developing complications, which is higher in individuals with known or suspected abnormalities of the genitourinary tract or weakened immune systems. The evidence for back-up antibiotic prescriptions is limited to non-pregnant women with lower UTIs where immediate antibiotic treatment is not deemed necessary. It is also important to consider previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria. Ultimately, the preferences of the woman regarding antibiotic use should be taken into account.

If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given, it is crucial to review the choice of antibiotic once the microbiological results are available. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The following antibiotics are recommended for non-pregnant women aged 16 years and older:

First-choice:
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Trimethoprim 200 mg taken orally twice daily for 3 days (if low risk of resistance*)

Second-choice (if there is no improvement in lower UTI symptoms on first-choice treatment for at least 48 hours, or if first-choice treatment is not suitable):
– Nitrofurantoin 100 mg modified-release taken orally twice daily for 3 days (if eGFR >45 ml/minute)
– Pivmecillinam 400 mg initial dose taken orally, followed by 200 mg taken orally three times daily for 3 days
– Fosfomycin 3 g single sachet dose

*The risk of resistance may be lower if the antibiotic has not been used in the past 3 months, previous urine culture suggests susceptibility (although this was not used), and in younger individuals in areas where local epidemiology data indicate low resistance rates. Conversely, the risk of resistance may be higher with recent antibiotic use and in older individuals in residential facilities.

Epididymo-orchitis refers to the inflammation of the testis and epididymis caused by an infectious source. The most common way of infection is through local extension, often resulting from infections spreading from the urethra or bladder.

In individuals below the age of 35, sexually transmitted pathogens like Chlamydia trachomatis and Neisseria gonorrhoeae are the primary causes. On the other hand, in individuals over the age of 35, non-sexually transmitted infections caused by Gram-negative enteric organisms that lead to urinary tract infections are more common.

Typically, patients with epididymo-orchitis experience sudden onset of unilateral scrotal pain and swelling. The affected testis is tender to touch, and there is usually a noticeable swelling of the epididymis that starts at the lower pole of the testis and spreads towards the upper pole. The testis itself may also be affected, and there may be redness and/or swelling of the scrotum on the affected side. Patients may have a fever and may also have urethral discharge.

It is crucial to consider testicular torsion as the most important differential diagnosis. This should be taken into account for all patients with sudden testicular pain, as the testicle needs to be saved within 6 hours of onset. Torsion is more likely in men under the age of 20, especially if the pain is extremely acute and severe. Typically, torsion presents around four hours after onset. In this case, the patient’s age, longer history of symptoms, and the presence of fever are more indicative of epididymo-orchitis.

Schistosomiasis, also known as bilharzia, is a tropical disease caused by parasitic trematodes (flukes) of the Schistosoma type. The transmission of this disease occurs when water becomes contaminated with faeces or urine containing eggs, and a specific freshwater snail serves as the intermediate host. Human contact with water inhabited by the intermediate host snail is necessary for transmission to occur.

There are five species of Schistosoma that can cause human disease: S. japonicum, S. mansoni, S. haematobium, S. intercalatum, and S. mekongi. Among these, S. japonicum and S. mansoni are the most significant causes of intestinal schistosomiasis, while S. haematobium is the primary cause of urogenital schistosomiasis.

Urogenital schistosomiasis occurs when adult worms migrate from their initial site in the liver to the vesical plexus. The presence of blood in the urine, known as haematuria, is a characteristic sign of urogenital schistosomiasis. In women, this condition may manifest with genital and vaginal lesions, as well as dyspareunia. pathology in the seminal vesicles and prostate. Advanced cases of urogenital schistosomiasis can result in fibrosis of the ureter and bladder, as well as kidney damage. Complications such as bladder cancer and infertility are also recognized in association with this disease.

Renal colic, also known as ureteric colic, refers to a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. This condition is commonly associated with the presence of a urinary tract stone.

The main symptoms of renal or ureteric colic include severe abdominal pain on one side, starting in the flank or loin area and radiating to the groin or testicle in men, or to the labia in women. The pain comes and goes in spasms, lasting for minutes to hours, with periods of no pain or a dull ache. Nausea, vomiting, and the presence of blood in the urine are often accompanying symptoms.

The pain experienced during renal or ureteric colic is often described as the most intense pain a person has ever felt, with many women comparing it to the pain of childbirth. Restlessness and an inability to find relief by lying still are common signs, which can help differentiate renal colic from peritonitis. Previous episodes of similar pain may also be reported by the individual. In cases where there is a concomitant urinary infection, fever and sweating may be present. Additionally, the person may complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and the bladder, as the stone irritates the detrusor muscle.

It is important to seek urgent medical attention if certain conditions are met. These include signs of systemic infection or sepsis, such as fever or sweating, or if the person is at a higher risk of acute kidney injury, such as having pre-existing chronic kidney disease, a solitary or transplanted kidney, or suspected bilateral obstructing stones. Hospital admission is also necessary if the person is dehydrated and unable to consume fluids orally due to nausea and/or vomiting. If there is uncertainty regarding the diagnosis, it is recommended to consult further resources, such as the NICE guidelines on the assessment and management of renal and ureteric stones.

For the treatment of men with lower urinary tract infection (UTI), it is recommended to offer an immediate prescription of antibiotics. However, certain factors should be taken into account. This includes considering previous urine culture and susceptibility results, as well as any history of antibiotic use that may have led to the development of resistant bacteria.

Before starting antibiotics, it is important to obtain a midstream urine sample from men and send it for culture and susceptibility testing. This will help determine the most appropriate choice of antibiotic.

Once the microbiological results are available, it is necessary to review the initial choice of antibiotic. If the bacteria are found to be resistant and symptoms are not improving, it is recommended to switch to a narrow-spectrum antibiotic whenever possible.

The first-choice antibiotics for men with lower UTI are trimethoprim 200 mg taken orally twice daily for 7 days, or nitrofurantoin 100 mg modified-release taken orally twice daily for 7 days if the estimated glomerular filtration rate (eGFR) is above 45 ml/minute.

If there is no improvement in lower UTI symptoms after at least 48 hours on the first-choice antibiotics, or if the first-choice is not suitable, it is important to consider alternative diagnoses and follow the recommendations in the NICE guidelines on pyelonephritis (acute): antimicrobial prescribing or prostatitis (acute): antimicrobial prescribing. The choice of antibiotic should be based on recent culture and susceptibility results.

Acute bacterial prostatitis is a sudden inflammation of the prostate gland, which can be either focal or diffuse and is characterized by the presence of pus.

A urine dipstick test showing white blood cells and a urine culture confirming urinary infection are also indicative of acute prostatitis.

The current recommendations by NICE and the British National Formulary (BNF) for the treatment of acute prostatitis involve prescribing an oral antibiotic for a duration of 14 days, taking into consideration local antimicrobial resistance data. The first-line antibiotics recommended are Ciprofloxacin 500 mg twice daily or Ofloxacin 200 mg twice daily. If these are not suitable, Trimethoprim 200 mg twice daily can be used. Second-line options include Levofloxacin 500 mg once daily or Co-trimoxazole 960 mg twice daily, but only when there is bacteriological evidence of sensitivity and valid reasons to prefer this combination over a single antibiotic.

Renal colic, also known as ureteric colic, refers to a sudden and intense pain in the lower back caused by a blockage in the ureter, which is the tube that carries urine from the kidney to the bladder. This condition is commonly associated with the presence of a urinary tract stone.

The main symptoms of renal or ureteric colic include severe abdominal pain on one side, starting in the lower back or flank and radiating to the groin or genital area in men, or to the labia in women. The pain comes and goes in spasms, lasting for minutes to hours, with periods of no pain or a dull ache. Nausea, vomiting, and the presence of blood in the urine are often accompanying symptoms.

People experiencing renal or ureteric colic are usually restless and unable to find relief by lying still, which helps to distinguish this condition from peritonitis. They may have a history of previous episodes and may also present with fever and sweating if there is an associated urinary infection. Some individuals may complain of painful urination, frequent urination, and straining when the stone reaches the junction between the ureter and the bladder, as the stone irritates the detrusor muscle.

In terms of pain management, the first-line treatment for adults, children, and young people with suspected renal colic is a non-steroidal anti-inflammatory drug (NSAID), which can be administered through various routes. If NSAIDs are contraindicated or not providing sufficient pain relief, intravenous paracetamol can be offered as an alternative. Opioids may be considered if both NSAIDs and intravenous paracetamol are contraindicated or not effective in relieving pain. Antispasmodics should not be given to individuals with suspected renal colic.

Epididymo-orchitis refers to the inflammation of the epididymis and/or testicle. It typically presents with sudden pain, swelling, and inflammation in the affected area. This condition can also occur chronically, which means that the pain and inflammation last for more than six months.

The causes of epididymo-orchitis vary depending on the age of the patient. In men under 35 years old, the infection is usually sexually transmitted and caused by Chlamydia trachomatis or Neisseria gonorrhoeae. In men over 35 years old, the infection is usually non-sexually transmitted and occurs as a result of enteric organisms that cause urinary tract infections, with Escherichia coli being the most common. However, there can be some overlap between these groups, so it is important to obtain a thorough sexual history in all age groups.

Mumps should also be considered as a potential cause of epididymo-orchitis in the 15 to 30 age group, as mumps orchitis occurs in around 40% of post-pubertal boys with mumps.

While most cases of epididymo-orchitis are infective, non-infectious causes can also occur. These include genito-urinary surgery, vasectomy, urinary catheterization, Behcet’s disease, sarcoidosis, and drug-induced cases such as those caused by amiodarone.

Patients with epididymo-orchitis typically present with unilateral scrotal pain and swelling that develops relatively quickly. The affected testis will be tender to touch, and there is usually a palpable swelling of the epididymis that starts at the lower pole of the testis and spreads towards the upper pole. The testis itself may also be involved, and there may be redness and/or swelling of the scrotum on the affected side. Patients may experience fever and urethral discharge as well.

The most important differential diagnosis to consider is testicular torsion, which requires immediate medical attention within 6 hours of onset to save the testicle. Testicular torsion is more likely in men under the age of 20, especially if the pain is very severe and sudden. It typically presents around four hours after onset. In this case, the patient’s age, longer history of symptoms, and the presence of fever are more indicative of epididymo-orchitis.

This patient is clearly experiencing pyelonephritis with systemic involvement, which may indicate sepsis. According to NICE guidelines, it is recommended to admit individuals to the hospital if they exhibit any symptoms or signs that suggest a more serious illness or condition, such as sepsis. In cases of acute pyelonephritis, it is advisable to consider referring or seeking specialist advice for individuals who are significantly dehydrated or unable to consume oral fluids and medications, pregnant women, those at a higher risk of developing complications (e.g., individuals with known or suspected structural or functional abnormalities of the genitourinary tract or underlying diseases like diabetes mellitus or immunosuppression), and individuals who have recurrent episodes of urinary tract infections (e.g., two or more episodes within a 6-month period). Additionally, it is recommended to consider referral for men who have experienced a single episode without an obvious cause and women with recurrent pyelonephritis. For more information, please refer to the NICE Clinical Knowledge Summary on the management of acute pyelonephritis.

All patients who present with painless haematuria should undergo cystoscopy to rule out bladder cancer. This procedure is typically done in an outpatient setting as part of a haematuria clinic, using a flexible cystoscope and local anaesthetic.

In this case, the likelihood of prostate cancer is much lower due to the patient’s relatively normal prostate examination and mild symptoms of bladder outlet obstruction.

Bladder cancer is the seventh most common cancer in the UK, with men being three times more likely to develop it than women. The main risk factors for bladder cancer are increasing age and smoking. Approximately 50% of bladder cancers are caused by smoking, which is believed to be due to the presence of certain chemicals that are excreted through the kidneys. Smokers have a 2-6 times higher risk of developing bladder cancer compared to non-smokers.

Painless macroscopic haematuria is the most common symptom in 80-90% of bladder cancer cases. There are usually no abnormalities found during a standard physical examination.

According to current recommendations, the following patients should be urgently referred for a urological assessment:
– Adults over 45 years old with unexplained visible haematuria and no urinary tract infection.
– Adults over 45 years old with visible haematuria that persists or recurs after successful treatment of a urinary tract infection.
– Adults aged 60 and over with unexplained non-visible haematuria and either dysuria or an elevated white cell count on a blood test.

For those aged 60 and over with recurrent or persistent unexplained urinary tract infection, a non-urgent referral for bladder cancer is recommended.
