Nitrofurantoin is currently the preferred antibiotic for treating uncomplicated urinary tract infections in non-pregnant women. However, antibiotic resistance is becoming a significant concern in the management of urinary tract infections and pyelonephritis in the UK. In England, the resistance of E. coli (the main bacteria causing these infections) to certain antibiotics is as follows:

Trimethoprim: 30.3% (varies between areas from 27.1% to 33.4%)
Co-amoxiclav: 19.8% (varies between areas from 10.8% to 30.7%)
Ciprofloxacin: 10.6% (varies between areas from 7.8% to 13.7%)
Cefalexin: 9.9% (varies between areas from 8.1% to 11.4%)

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.

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.

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.

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.

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.

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.

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.
