Treatment Overview
About Hydrocele repair (Surgery)
A hydrocele repair (medically known as a hydrocelectomy) is a straightforward operation to remove a collection of fluid that has built up in the sac surrounding the testicle. This fluid causes the scrotum to swell, which can feel heavy, uncomfortable, or simply look unusual.
During the surgery, the fluid is drained, and the specialist either removes the excess sac tissue or folds it back to prevent the fluid from ever returning. We use refined techniques (such as the 'Lord's' or 'Jaboulay' methods) to ensure the repair is as neat and permanent as possible. Unlike simply draining the fluid with a needle, this surgery fixes the underlying cause so you don't have to worry about the swelling coming back.
Safety Information
Benefits, Risks & Side Effects
01
Benefits
The primary benefit is getting rid of that heavy, dragging sensation and the visible swelling for good.
A Permanent Fix: Unlike needle aspiration, which almost always results in the fluid coming back, surgery is a long-term solution.
Peace of Mind: The procedure allows the surgeon to confirm that your testicle is healthy and that the swelling wasn't hiding any other issues.
Restored Comfort: Most men find they can return to their favourite activities and wear normal clothing without discomfort once they have healed.
02
Risks
Hydrocele repair is a very common and safe operation. The most frequent minor risk is an internal blood clot or significant bruising (haematoma) inside the scrotum, which happens in about 3–5% of cases.
There is a small risk of a minor infection (about 2%) and a very low risk (less than 1%) of any injury to the delicate tubes or blood vessels that support the testicle. While the surgery is very effective, there is a small chance (2–5%) that a hydrocele could return in the future.
03
Side Effects
The most common side effect is swelling and bruising. In fact, for the first week, the swelling might make the area look just as large as it did before the surgery—don't worry, this is normal and will go down.
You will likely feel a 'heavy' dull ache in the groin and scrotum for a few days, which can be managed with simple painkillers. Some men also notice that the testicle feels slightly different or sits in a new position once the fluid is gone.

Patient Journey
What to Expect
A step-by-step guide through your Hydrocele repair (Surgery) journey—from preparation and what happens during the procedure to recovery and aftercare.
01/ 03
Before Procedure
To ensure everything is ready, you will usually have a quick ultrasound scan to confirm the swelling is definitely a hydrocele.
Health Check: You’ll have a pre-operative assessment and provide a urine sample to rule out any infection.
Preparation: You may be asked to gently shave the area on the morning of your surgery.
Fasting: As you will likely have a general anaesthetic (where you are asleep), you must not eat or drink (nil by mouth) for 6 hours before the operation.
02/ 03
During Procedure
The surgery is a 'day-case' procedure, meaning you’ll usually be home within a few hours. It takes about 30 to 45 minutes.
While you are asleep, the surgeon makes a small incision (cut) in the scrotum.
The fluid is drained away safely.
The sac is either trimmed or stitched back behind the testicle to ensure fluid cannot build up again.
The skin is closed using fine, dissolvable stitches that you won't need to have removed.
03/ 03
After Procedure
Recovery is all about support and patience.
Support: You must wear tight, supportive underwear (like a jockstrap or 'brief' style pants) 24 hours a day for the first 2 weeks. This is the best way to prevent swelling and pain.
Ice Packs: Use a cold pack wrapped in a towel for 10–15 minutes several times a day during the first 48 hours.
Rest: Avoid heavy lifting and the gym for 2 to 4 weeks. You can usually get back to an office job within 5 to 7 days.
Healing: Your stitches will dissolve on their own, usually within 2 to 3 weeks.

Frequently Asked Questions
Common questions about this treatment and what to expect.

While we can drain the fluid with a needle (aspiration), it is almost guaranteed to return, often within a few weeks or months. Aspiration also carries a risk of introducing an infection into the sac. Surgery is the only 'permanent' fix because it removes or alters the sac that is actually producing and holding the fluid.

Not necessarily. Scrotal tissue is very loose and prone to swelling (oedema) and internal bruising after surgery. It is very common for the scrotum to look just as large—or even larger—than before the operation for the first 7 to 10 days. As long as the area isn't becoming increasingly painful, red, or hot, this is usually just the normal healing process.

A standard hydrocele repair does not involve the testicle itself or the tubes that carry sperm; it only deals with the sac around the testicle. Therefore, it has no impact on your testosterone production or your ability to father children. In very rare cases, significant post-operative infection or haematoma could affect the testicle, but this is extremely uncommon
