Surgery
Hydrocele Repair
Hydrocele repair removes or drains a fluid-filled swelling around a testicle when it is large or uncomfortable.
Quick answer
Hydrocele Repair: what it is, why it's done and what happens
A hydrocele is a build-up of fluid in the sac around a testicle, causing painless scrotal swelling. Repair surgery removes or seals the sac so fluid no longer collects.
- Why it is done: It is used for a hydrocele that is large, uncomfortable, growing, or causing concern, particularly when it does not settle on its own, as often happens in adults.
- What happens: Under general or spinal anaesthetic, the surgeon makes a small cut in the scrotum (or groin in children), drains the fluid and removes or folds back the sac.
What it is
A hydrocele is a build-up of fluid in the sac around a testicle, causing painless scrotal swelling. Repair surgery removes or seals the sac so fluid no longer collects.
Why it is done
It is used for a hydrocele that is large, uncomfortable, growing, or causing concern, particularly when it does not settle on its own, as often happens in adults.
What happens
Under general or spinal anaesthetic, the surgeon makes a small cut in the scrotum (or groin in children), drains the fluid and removes or folds back the sac. It is usually a day-case operation.
Recovery
Swelling and bruising settle over one to two weeks, helped by supportive underwear, pain relief and rest. Most people return to normal activities within a couple of weeks.
Good to know
Risks and things to consider
Risks include bleeding or a blood collection (haematoma), infection, and the hydrocele occasionally returning. Serious complications are uncommon.

Answers
Hydrocele Repair: frequently asked questions
Does a hydrocele always need surgery?
No. Small, painless hydroceles often need no treatment, and in babies many resolve on their own. Surgery is considered when it is large, uncomfortable or persistent, or the cause needs checking.
Can a hydrocele come back after surgery?
Recurrence is uncommon after surgical repair, though it can happen. Draining a hydrocele with a needle alone, without surgery, is more likely to allow it to return.
