Hydrocele Definition
A hydrocele is a fluid-filled sac surrounding a testicle that causes swelling in the scrotum. It is a common condition in newborns but can also occur in older males due to injury or inflammation within the scrotum.
Hydrocele Aetiology
Hydroceles can be congenital or acquired:
- Congenital Hydrocele: Present at birth due to incomplete closure of the processus vaginalis.
- Acquired Hydrocele: Can result from injury, infection (such as epididymitis or orchitis), or tumours in the scrotum.
Hydrocele Pathophysiology
The fluid accumulation in a hydrocele occurs due to an imbalance between fluid secretion and absorption in the tunica vaginalis. In congenital hydrocele, the processus vaginalis remains open, allowing peritoneal fluid to enter the scrotal sac. In acquired hydrocele, fluid accumulates due to inflammation, injury, or blockage of lymphatic drainage.
Hydrocele Risk Factors
- Premature birth
- Injury or trauma to the scrotum
- Infections such as epididymitis or orchitis
- Previous surgery in the scrotal or inguinal area
Hydrocele Symptoms
The primary symptom of a hydrocele is painless swelling of one or both testicles. In some cases, the swelling may cause discomfort due to its size.
Hydrocele Investigations
- Clinical history and physical examination, including transillumination of the scrotum
- Ultrasound: To confirm the diagnosis and rule out other conditions such as hernia or testicular tumour
Hydrocele Management
Primary Care Management
- Observation: Many hydroceles resolve on their own, especially in infants.
- Referral: If the hydrocele persists, causes discomfort, or is associated with other symptoms, referral to a specialist is advised.
Specialist Management
- Surgery: If the hydrocele persists or causes discomfort, surgical removal (hydrocelectomy) may be necessary.
- Aspiration: In some cases, fluid can be aspirated, although this is less common due to the risk of infection and recurrence.
Varicocele Definition
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins that can occur in the legs. Varicoceles are a common cause of low sperm production and decreased sperm quality, which can lead to infertility.
Varicocele Aetiology
Varicoceles form when the valves inside the veins in the spermatic cord prevent blood from flowing properly. This causes the veins to dilate (enlarge). The exact cause is not always clear but may involve:
- Valve dysfunction within the veins.
- Pressure differences due to anatomical variations.
Varicocele Pathophysiology
Varicoceles occur due to the failure of the valves within the spermatic veins, which leads to pooling of blood and increased pressure in the veins. This can cause the veins to dilate and become tortuous. The resulting increased temperature in the scrotum may affect sperm production and function.
Varicocele Risk Factors
- Age: Most common in males aged 15-25 years.
- Height: Taller men may be at higher risk.
- Genetics: Family history of varicocele.
Varicocele Symptoms
Symptoms of a varicocele may include:
- A dull, aching pain in the scrotum.
- Swelling or a lump in the scrotum.
- Visible or palpable enlarged veins ("bag of worms" sensation).
- Infertility or reduced fertility.
Varicocele Investigations
- Clinical history and physical examination, including palpation of the scrotum
- Ultrasound: To confirm the diagnosis and assess the extent of the varicocele
- Semen analysis: To evaluate sperm quality and quantity in cases of infertility
Varicocele Management
Primary Care Management
- Observation: If the varicocele is not causing symptoms or fertility problems, monitoring may be all that is needed.
- Referral: If symptoms persist or if there are concerns about fertility, referral to a specialist is advised.
Specialist Management
- Surgery: Varicocelectomy can be performed to seal off the affected veins and redirect blood flow to normal veins.
- Embolization: A minimally invasive procedure where a coil or agent is used to block the affected veins.
