Assessing Prostate Enlargement: Diagnostic Tests and Treatment Options

To determine the presence and severity of prostate enlargement, a full urological history should be taken, with attention paid to obstructive and irritation symptoms. If enlargement is suspected, a blood test for prostate-specific antigen (PSA) should be done before rectal examination, as the latter can increase PSA levels. Tamsulosin may be prescribed as a first-line drug for mild cases, but a thorough history should be obtained before starting pharmacological treatment. Abdominal examination is not typically necessary for initial diagnosis.

While patients assigned male at birth who are undergoing treatment with oestradiol, GNRH analogs, finasteride or cyproterone may experience a decrease or cessation in sperm production, it is not a reliable method of contraception. Therefore, it is important to advise the use of condoms as a suitable option for contraception. It is incorrect to suggest that a vasectomy is the only option, as condoms are also a viable choice. Additionally, recommending that the patient’s partner use hormonal contraception is not appropriate, as advice should be given directly to the patient.

Contraceptive and Sexual Health Guidance for Transgender and Non-Binary Individuals

The Faculty of Sexual & Reproductive Healthcare has released guidance on contraceptive choices and sexual health for transgender and non-binary individuals. The guidance emphasizes the importance of sensitive communication and offering options that consider personal preferences, co-morbidities, and current medications or therapies.

For individuals engaging in vaginal sex where there may be a risk of pregnancy and/or sexually transmitted infections, condoms and dental dams are recommended. Cervical screening and human papillomavirus vaccinations should also be offered to sexually active individuals with a uterus. Those engaging in anal sex and rimming should be advised of the risk of hepatitis A & B and offered vaccinations. Individuals at risk of HIV transmission should be advised of the availability of pre-exposure prophylaxis and post-exposure prophylaxis as required.

For patients seeking permanent contraception, a fallopian tube occlusion or a vasectomy may be the most appropriate solution and neither would be affected by hormonal therapy. Testosterone therapy does not provide protection against pregnancy, and oestrogen-containing regimes are not recommended in patients undergoing testosterone therapy. Progesterone-only contraceptives are considered safe, and the intrauterine system and injections may also suspend menstruation. Non-hormonal intrauterine devices do not interact with hormonal regimes but can exacerbate menstrual bleeding.

In patients assigned male at birth, there may be a reduction or cessation of sperm production with certain therapies, but the variability of effects means they cannot be relied upon as a method of contraception. Condoms should be recommended in those patients engaging in vaginal sex wishing to avoid the risk of pregnancy. Emergency contraception may be required in patients assigned female at birth following unprotected vaginal intercourse, and either of the available oral emergency contraceptive options may be considered. The non-hormonal intrauterine device may also be an option, but it may have unacceptable side effects in some patients.

Overall, the guidance stresses the importance of individualized care and communication in contraceptive and sexual health decisions for transgender and non-binary individuals.

Understanding the Types and Timing of Transplant Rejection

Transplant rejection can occur in different types and at different times after transplantation. Hyperacute rejection is the earliest and occurs within minutes of transplantation due to pre-existing donor-specific antibodies. This reaction is complement-mediated and irreversible, requiring prompt removal of the transplanted tissue. Acute rejection can occur up to 3 months after transplantation and is cell-mediated, involving the activation of phagocytes and cytotoxic T lymphocytes. Rejection that occurs in the first few days after transplantation is known as accelerated acute rejection. Chronic rejection, which is controversial, involves antibody-mediated vascular damage and can occur months to years after transplantation. Blood group matching can minimize hyperacute rejection, while monitoring and immunosuppressive therapy can help prevent and treat other types of rejection.

Possible Causes of Infertility in a Young Man

Infertility in a young man can have various causes. One possible cause is Kartagener’s syndrome, a rare autosomal recessive genetic disorder that affects the action of Ciliary lining the respiratory tract and flagella of sperm cells. This syndrome can lead to recurrent respiratory infections and poor sperm motility. Another possible cause is cryptorchidism, the absence of one or both testes from the scrotum, which can reduce fertility even after surgery. Age-related hormonal changes or atherosclerosis can also affect fertility, but these are less likely in a young, healthy man with normal blood tests. Cystic fibrosis, a genetic disorder that affects the lungs and digestive system, can also cause infertility, but it is usually detected early in life and has additional symptoms such as poor weight gain and diarrhea.

Best Practices for Permanent Indwelling Urinary Catheters

Introduction:
Permanent indwelling urinary catheters are commonly used in patients with urinary retention or incontinence. However, they can pose a risk of infection and other complications. Therefore, it is important to follow best practices when placing and maintaining these catheters.

Prophylactic Gentamicin:
When replacing a permanent catheter, it is recommended to administer a single dose of prophylactic gentamicin to prevent infection.

Regular Replacement:
It is essential to have measures in place for regular routine replacement of permanent catheters. This is because they are a foreign body and can be a portal of entry for infection. Urinary sepsis in these patients can be devastating and fatal.

Same-Sized Catheter:
When replacing a catheter, it is not necessary to change the size unless there are symptoms of catheter bypass. Increasing the size can cause pain and trauma.

Local Anaesthetic Gel:
Even if a patient has paraparesis, local anaesthetic gel must be used during catheter insertion to prevent pain.

Chaperone:
It is good practice to offer a chaperone during any intimate examination/procedure. The patient may accept or decline a chaperone. If a chaperone is required, they do not have to be a man as long as there is consent from the patient.

Regular Replacement Schedule:
Long-term catheters require changing every 12 weeks due to the design of the catheter and the risk of infection. This can be done in the community by district nurses.

Best Practices for Permanent Indwelling Urinary Catheters

If a patient presents with menorrhagia along with pelvic pain, abnormal exam findings, or intermenstrual or postcoital bleeding, it is recommended to conduct a transvaginal ultrasound. According to the NICE guidelines, a transvaginal ultrasound should be preferred over a transabdominal ultrasound or MRI for women with significant dysmenorrhoea or a bulky, tender uterus on examination that suggests adenomyosis.

In the case of Lila, who is experiencing new menorrhagia and significant dysmenorrhoea, a transvaginal ultrasound is necessary. If a transvaginal ultrasound is not possible, a transabdominal ultrasound or MRI can be considered, but the limitations of these techniques should be explained.

For women without identified pathology, fibroids less than 3 cm in diameter, or suspected or diagnosed adenomyosis, the first-line treatment recommended by the guideline is a levonorgestrel intrauterine system (LNG-IUS). While this may be an appropriate treatment for Lila, the initial next step should be to arrange for a transvaginal ultrasound to investigate further. At this stage, there are no red flags in Lila’s history or examination that warrant an urgent referral to gynaecology.

Managing Heavy Menstrual Bleeding

Heavy menstrual bleeding, also known as menorrhagia, is a condition where a woman experiences excessive blood loss during her menstrual cycle. While it was previously defined as total blood loss of over 80 ml per cycle, the management of menorrhagia now depends on the woman’s perception of what is excessive. In the past, hysterectomy was a common treatment for heavy periods, but the approach has changed significantly since the 1990s.

To manage menorrhagia, a full blood count should be performed in all women. If symptoms suggest a structural or histological abnormality, a routine transvaginal ultrasound scan should be arranged. For women who do not require contraception, mefenamic acid or tranexamic acid can be used. If there is no improvement, other drugs can be tried while awaiting referral.

For women who require contraception, options include the intrauterine system (Mirena), combined oral contraceptive pill, and long-acting progestogens. Norethisterone can also be used as a short-term option to rapidly stop heavy menstrual bleeding.

Anatomy of the Male Reproductive System

The male reproductive system is a complex network of organs and structures that work together to produce and transport sperm. Here are some key components of this system:

Pampiniform Plexus: This network of veins runs along the spermatic cord and drains blood from the scrotum. When these veins become dilated, it can result in a condition called varicocele, which may cause a bag of worms sensation in the scrotum.

Ductus Deferens: This tube-like structure is part of the spermatic cord and carries sperm and seminal fluid from the testis to the ejaculatory duct.

Processus Vaginalis: This structure can sometimes be present in the groin area and may communicate with the peritoneum. When it does, it can lead to a condition called hydrocele, where fluid accumulates in the scrotum.

Testicular Artery: This artery originates from the abdominal aorta and supplies blood to the testis. It is not involved in the formation of varicocele.

Genital Branch of the Genitofemoral Nerve: This nerve provides sensation to the skin in the upper anterior part of the scrotum and innervates the cremaster muscle. It is not involved in the formation of varicocele.

Understanding the anatomy of the male reproductive system can help in identifying and treating various conditions that may affect it.

Management of Penile Conditions: Differentiating Paraphimosis and Balanitis

Penile conditions such as paraphimosis and balanitis require prompt and appropriate management. Paraphimosis occurs when the foreskin is retracted but cannot be replaced, leading to swelling of the glans penis. This is a urological emergency that requires immediate intervention. Treatment involves attempting to manually reduce the foreskin, aided by a hypertonic solution to draw out fluid from the swollen area. Referral to Urology is necessary if reduction is not successful.

Balanitis, on the other hand, is inflammation of the foreskin usually caused by dermatitis or infection with Candida, Gardnerella, or staphylococcal organisms. Symptoms include tenderness and erythema of the glans penis, itching, penile discharge, difficulty with retraction of the foreskin, and difficulty urinating or controlling urine stream. Treatment involves prescribing a 7-day course of hydrocortisone and clotrimazole cream or flucloxacillin if caused by Staphylococcus aureus.

It is important to differentiate between these two conditions and provide appropriate management to prevent complications.

Understanding Testicular Cancer and Tumours

Testicular cancer is a common malignancy affecting men aged 20-39 years, with a high overall 5-year survival rate of 95%. Serum tumour markers such as βHCG and LDH are used to aid diagnosis and monitor response to treatment and detect recurrent disease. Leydig and Sertoli cell tumours are classified as sex cord/gonadal stromal tumours and may produce excess testosterone or oestrogen. Non-seminomatous germ cell tumours (NSGCTs) including yolk sac tumours, embryonal carcinomas, choriocarcinomas and teratomas may produce αFP, while seminomas do not. Teratomas of the testicle, a type of germ cell tumour, secrete αFP in approximately 70% of cases. Understanding the different types of testicular cancer and tumours is important for accurate diagnosis and treatment.

Treatment Options for Benign Prostatic Hyperplasia (BPH)

Benign prostatic hyperplasia (BPH) is a common condition that presents with obstructive lower urinary symptoms. Over time, irritative lower urinary tract symptoms can develop due to bladder outflow obstruction, detrusor hypertrophy, and a resulting overactive bladder. The examination typically reveals a smooth and symmetrically enlarged prostate gland, and a PSA level >1.5 indicates significant risk of progression of prostate enlargement.

There are several treatment options for BPH, depending on the severity of symptoms and prostate enlargement. Lifestyle adaptation, such as sensible fluid intake, reduction of caffeine and alcohol, and management of constipation, can often be effective. If symptoms are troublesome, treatment with an alpha-blocker like tamsulosin can be tried. If the prostate is significantly enlarged or PSA is >1.5, then finasteride, a 5a-reductase inhibitor that will shrink the prostate over time, can be added.

Anticholinergic medications like oxybutynin can be used to relieve urinary and bladder difficulties, but these are not typically used first line. Prostate biopsy is not always necessary, and contraindications include the surgical absence of a rectum or the presence of a rectal fistula.
