What is a Hydrocele?
A hydrocele is a collection of fluid within the tunica vaginalis — the thin, sac-like membrane that normally surrounds each testicle. When the balance between fluid produced and fluid absorbed by this sac is disturbed, fluid may accumulate and cause the scrotum to become enlarged. Most hydroceles are soft, non-tender swellings and are not cancerous.
Hydroceles can occur at any age, from newborn babies through to older adults. In many patients they are noticed as a gradual, painless swelling of one side (sometimes both sides) of the scrotum. Because other conditions can also cause scrotal swelling, a clinical evaluation is important to confirm the diagnosis.
Types of Hydrocele
Symptoms
- Painless swelling of the scrotum, on one or both sides
- A feeling of heaviness or dragging in the scrotum
- Gradual increase in size over weeks or months
- Cosmetic concern due to the size of the swelling
- Difficulty with clothing, walking, or physical activity when the swelling is large
A hydrocele is usually not painful. If pain, tenderness or redness develops, it may indicate infection or another condition, and a clinical review is advised.
When to See a Surgeon
Seek prompt medical attention if you experience: a sudden painful scrotal swelling, severe tenderness, redness, high fever with scrotal symptoms, or rapidly increasing swelling. These may indicate testicular torsion, infection or other emergencies that need urgent evaluation and treatment.
Even in the absence of emergency features, any persistent or enlarging scrotal swelling should be evaluated by a surgeon to confirm the diagnosis and to exclude other conditions.
Causes
The underlying mechanism is usually an imbalance between the fluid produced by the lining of the sac and the fluid absorbed by it. Common contributing factors include:
- Idiopathic — no clear cause, particularly in older men
- Previous injury to the scrotum or perineum
- Inflammation or infection of the testicle or epididymis
- Post-surgical, for example after hernia or scrotal surgery in some patients
- Filariasis in areas where this parasitic infection is endemic
- Congenital — a small persistent channel from the abdomen in children
Diagnosis
Most hydroceles can be diagnosed with a careful clinical examination. Useful assessments include:
- Clinical examination of the scrotum, including palpation of the testicle
- Transillumination — shining a light through the scrotum; a hydrocele typically transmits light
- Ultrasound of the scrotum to confirm the diagnosis, assess the testicle, and exclude other conditions such as a hernia, epididymal cyst or a testicular lump
- Additional blood or urine tests if infection is suspected
Treatment
Not every hydrocele needs immediate surgical treatment. Small, asymptomatic hydroceles that are not enlarging may be observed with periodic review. However, when a hydrocele is symptomatic, cosmetically bothersome or progressively enlarging, surgery is usually advised.
Hydrocelectomy (day-care surgery)
Symptomatic or enlarging hydroceles are commonly treated with a short, day-care surgical procedure. The fluid is drained and the sac is dealt with so that fluid does not re-accumulate. Commonly used techniques include:
- Jaboulay's procedure — the sac is opened and its edges are turned inside out and secured behind the testicle
- Lord's plication — the sac is plicated (bunched with stitches) to reduce the space in which fluid can collect, often used for thin-walled hydroceles
The choice of technique depends on the size and characteristics of the hydrocele and the surgeon's assessment during the operation.
Note on aspiration
Simple aspiration of the fluid using a needle may temporarily reduce the swelling, but the fluid often re-accumulates and there is a risk of infection or bleeding. Aspiration is therefore not generally considered a definitive treatment for most hydroceles.
Recovery
Recovery after hydrocelectomy is usually short. Many patients are discharged on the same day or the following day, depending on the case. Mild swelling, bruising and discomfort at the operated area are common in the early days and typically settle with prescribed medication and supportive measures. Wound care, use of a scrotal support and activity restrictions are advised as per the surgeon's individualised guidance. Return to office work is often possible within a few days, while heavy lifting or strenuous activity usually requires a longer break.
Paediatric Hydrocele
Hydroceles are common in newborn boys and often resolve on their own during the first one to two years of life. If a hydrocele persists beyond this age, is large, or is associated with a hernia, surgical correction through an inguinal (groin) approach is usually recommended. Paediatric hydrocele repair is generally a short procedure with a good recovery, and follow-up helps confirm healing.
Frequently Asked Questions
What is a hydrocele?
A hydrocele is a collection of fluid in the tunica vaginalis around the testicle. It usually presents as a soft, painless swelling of the scrotum.
Is a hydrocele cancerous?
A hydrocele itself is not cancerous. However, other conditions can also cause scrotal swelling, which is why clinical evaluation and, if needed, an ultrasound are recommended.
Can a hydrocele resolve without surgery?
In infants, congenital hydroceles often resolve on their own in the first one to two years. In adults, hydroceles usually do not disappear on their own and are treated with surgery if symptomatic.
What is hydrocelectomy?
Hydrocelectomy is a surgical procedure — commonly Jaboulay's or Lord's technique — in which the fluid is drained and the sac is reconfigured to prevent re-accumulation.
Is aspiration of the fluid a permanent solution?
Simple aspiration often results in re-accumulation of fluid and carries some risk of infection. Surgery is usually the more definitive treatment for symptomatic hydroceles.
How soon can I return to work after hydrocele surgery?
Recovery varies. Many patients resume office work within a few days, while heavy lifting and strenuous activity usually need longer, as advised by the surgeon.
Is hydrocele surgery covered by mediclaim / health insurance?
Hydrocele surgery is generally covered under most health insurance policies. Madhav Hospital offers mediclaim / insurance facility — please confirm coverage with your insurer.
