Hydrocele Surgery in Turkey
A hydrocele is a painless build-up of fluid around a testicle. In adult men it rarely goes away on its own, so surgery is the reliable fix. Assoc. Prof. Tuncay Taş explains when to operate, which method suits you, and how recovery goes in Istanbul.

What is a hydrocele?
A hydrocele is a collection of clear fluid inside the thin sac that surrounds a testicle. As a result, one side of the scrotum swells, often like a soft water balloon.
Most hydroceles are harmless and do not affect the testicle itself. However, a large one can drag, ache, show through clothing and get in the way of sport or sex.
In baby boys, many hydroceles clear by the age of two. In adult men, by contrast, they usually stay or grow. So when the swelling bothers you, an operation called hydrocelectomy is the standard treatment.
Which question brought you here?
Most men ask one of five things after they notice a swollen scrotum. So pick the closest one and jump straight to the answer.
Types and causes of hydrocele in adults
Doctors sort hydroceles by cause, because the cause changes the plan. In fact, the type also decides where the surgeon makes the cut.
Simple (idiopathic) hydrocele: the most common type in men. The sac makes a little more fluid than it absorbs, with no clear cause.
Communicating hydrocele: a small channel to the abdomen stays open, so the swelling changes size during the day. This type often comes with a hernia.
Secondary hydrocele: fluid forms after infection, injury or surgery, or around a testicular tumour.
Hydrocele after varicocele surgery: lymph drainage can change after a varicocele operation. Microsurgical technique lowers this risk.
Also, in some tropical regions, a parasite infection can cause very large hydroceles. Men who have lived in those areas should mention it at the first visit.
How doctors diagnose a hydrocele
A hydrocele often looks obvious. Still, a scrotal swelling can have several causes, so a proper check comes before any treatment.
Symptoms men notice
Swelling on one side: smooth, soft and usually painless.
Heaviness: a dragging feeling that gets worse by evening.
Size changes: a swelling that shrinks overnight points to a communicating hydrocele or hernia.
Discomfort: rubbing, trouble with tight clothing, or pain during exercise or sex.
Tests before treatment
Examination: the urologist feels the swelling, the testicle and the groin, and checks for a hernia.
Light test: a torch shines through clear fluid, which helps tell fluid from a solid lump.
Scrotal ultrasound: the key test. It shows the testicle behind the fluid and rules out a tumour, infection or varicocele.
Blood tests: only if the ultrasound shows something solid or suspicious.
Above all, a hydrocele can hide a testicular tumour, especially in younger men. That is why Assoc. Prof. Taş never operates on a hydrocele without a clear ultrasound of the testicle. If a tumour is found, the plan follows the testicular cancer surgery pathway instead.
Hydrocele or something else?
Several conditions cause a swollen scrotum, and some feel alike. Therefore, the table shows how a urologist tells them apart.
Hydrocele
How it usually feels: Smooth, soft, painless swelling around the whole testicle
Key test: Ultrasound shows clear fluid
Usual treatment: Watch, or hydrocelectomy
Inguinal hernia
How it usually feels: Bulge that runs up into the groin and grows on coughing
Key test: Examination, sometimes ultrasound
Usual treatment: Hernia repair
Varicocele
How it usually feels: Soft veins above the testicle, often on the left
Key test: Doppler ultrasound
Usual treatment: Watch, or varicocelectomy
Epididymal cyst
How it usually feels: Small, separate lump above or behind the testicle
Key test: Ultrasound
Usual treatment: Watch, or removal if large
Epididymitis
How it usually feels: Painful, warm swelling, sometimes with fever
Key test: Urine test and ultrasound
Usual treatment: Antibiotics
Testicular tumour
How it usually feels: Firm lump within the testicle itself
Key test: Ultrasound and blood markers
Usual treatment: Orchiectomy through the groin
In practice, two of these can occur together, for example a hydrocele with a hernia. That is why the examination and ultrasound always come first.
Varicoceles often sit above a hydrocele and can affect sperm quality. For more detail, see the microscopic varicocelectomy page.
When does a hydrocele need surgery?
If a small hydrocele causes no trouble, you can simply keep an eye on it. Surgery makes sense once the swelling affects daily life.
Small, painless, not growing
Usual advice: Watch and recheck
Why: No harm to the testicle, so no need to operate
Large, heavy or uncomfortable
Usual advice: Hydrocelectomy
Why: Adult hydroceles rarely shrink by themselves
Swelling that changes size
Usual advice: Surgery through the groin
Why: An open channel or hernia needs closing
Hydrocele with a testicular lump
Usual advice: Cancer pathway first
Why: The tumour decides the operation
Hydrocele after varicocele surgery
Usual advice: Watch, then surgery if it persists
Why: Some settle within months
Fit for surgery is in doubt
Usual advice: Drainage with sclerotherapy
Why: Less invasive, but fluid often returns
In short, the size and your symptoms decide, not a number on the scan. So he discusses your own goals, such as sport, work or planning a family, before he recommends surgery.
Living with a hydrocele if you decide to wait
Many men with a small hydrocele choose not to have surgery straight away. That is a reasonable choice, as long as an ultrasound has ruled out other causes.
Support helps: snug briefs reduce the dragging feeling during the day.
Watch the size: note whether it grows over months, since steady growth favours surgery.
Check the testicle: a monthly self-exam still matters, even with fluid around it.
Avoid repeated drainage: each needle drainage brings back the fluid and adds a small infection risk.
Also, see a doctor soon if the swelling turns red, hot or painful, or if you feel a hard lump. These signs point to a different problem that needs prompt care.
Hydrocele treatment options compared
There are three main ways to treat an adult hydrocele. Each one trades a little more surgery for a lower chance of the fluid coming back.
Needle drainage alone
How it works: Fluid drawn off with a needle
Fluid returns: Almost always, within weeks
Best suited to: Short-term relief only
Drainage with sclerotherapy
How it works: Fluid drained, then a medicine makes the sac stick together
Fluid returns: Fairly often, may need repeats
Best suited to: Men who cannot have an anaesthetic
Hydrocelectomy (surgery)
How it works: The sac is opened, emptied and folded or partly removed
Fluid returns: Uncommon
Best suited to: Most adult men who want a lasting fix
Needle drainage also carries a small risk of infection and bleeding into the scrotum. Therefore, for most healthy men, a single well-planned operation is the better choice.
How hydrocelectomy is done
Assoc. Prof. Taş chooses the technique to fit the size and wall of your hydrocele. The aim is a lasting result with as little handling of tissue as possible.
Plication (Lord's technique)
For small and medium hydroceles with a thin wall, he empties the sac and gathers its wall with fine stitches. Because this needs little dissection, bruising and swelling tend to be lower.
Eversion or partial excision
For large or thick-walled hydroceles, he turns the sac inside out behind the testicle (Jaboulay technique) or trims away the excess wall. As a result, the lining can no longer collect fluid.
Groin approach
If the hydrocele communicates with the abdomen, or if a hernia is present, the cut goes in the groin instead. That way, he can close the open channel at its source.
Protecting fertility
The tube that carries sperm (epididymis) lies right against the sac. So he takes particular care around it, which matters most for men who still plan to have children.
Your hydrocele surgery in Istanbul
The whole trip usually fits into four to six days. Furthermore, you agree every step with Assoc. Prof. Taş before you book a flight.
01
Consultation and ultrasound
First, he examines you and repeats the scrotal ultrasound in Istanbul. Then he confirms the type of hydrocele and the method.
02
Pre-operative checks
Next, routine blood tests and an anaesthesia review take place, usually on the same day. He also reviews any blood thinners you take.
03
The operation
Then, under general or spinal anaesthesia, the operation takes about 30 to 60 minutes. He places a small drain only for very large hydroceles.
04
Check and discharge
Finally, most men go home the same day or after one night. Before you fly, he checks the wound and the swelling.
How long to stay in Istanbul
Plan about four to six days in total. In addition, add a day or two if he also repairs a hernia.
Recovery after hydrocele surgery
Recovery is quick for most men, but the scrotum stays swollen for a while. In fact, it often looks bigger in the first days than before surgery, and this is normal.
Walking around
The same day
Desk work
After about 3 to 7 days
Driving
After about 1 week, once you can brake without pain
Flying home
After about 3 to 5 days
Sex
After about 2 to 3 weeks
Gym, cycling and heavy lifting
After about 4 weeks
Final shape of the scrotum
Usually 6 to 12 weeks
Simple steps that help
Snug support: wear supportive briefs or a scrotal support day and night for the first two weeks.
Cold packs: wrapped in a cloth, for short periods in the first 48 hours.
Pain relief: regular simple painkillers are usually enough.
Wound care: keep the cut dry for 48 hours, then shower as advised.
Risks of hydrocele surgery
Hydrocelectomy is a common and generally safe operation. Even so, every surgery carries some risk.
Bruising or a blood collection: the most common problem. Most settle with rest and support; a few need draining.
Long-lasting swelling: firm swelling can take a few months to go down fully.
Infection: uncommon, and treated with antibiotics.
Return of the fluid: uncommon after surgery, but more likely after drainage.
Ongoing ache: rare, and usually improves over time.
Injury to the epididymis or testicle: rare, but important for fertility, so careful technique matters.
Moreover, he explains your personal risks in detail before you consent to surgery.
How much does hydrocele surgery cost in Turkey?
Assoc. Prof. Taş gives each patient a personal written quote after the examination and ultrasound. That is because the size, the technique and any hernia repair change the price.

Travelling from the US, Canada or the UK
A hydrocele is not an emergency, so you can plan the trip calmly. Still, a few steps keep care joined up with your doctor at home.
Before you fly
Bring any scrotal ultrasound report you already have, with the date.
Bring a list of your medicines, especially blood thinners.
Pack snug, supportive underwear for the flight home.
Seek help urgently instead
Sudden, severe pain or a hard, painful swelling is not a hydrocele symptom. In that case, go to an emergency department near you straight away, because the testicle may be twisted.
Back home
You leave with an operation note and a recovery plan in English. Then your family doctor can check the wound and the swelling if needed.

Frequently asked questions
Will a hydrocele go away on its own?
In babies it often does. In adult men, however, a hydrocele usually stays or slowly grows.
Is a hydrocele dangerous?
Usually not. Still, you need an ultrasound to rule out a tumour or infection behind the fluid.
Can a hydrocele be treated without surgery?
Drainage with sclerotherapy is an option, but the fluid comes back more often than after surgery.
How long does hydrocele surgery take?
The operation takes about 30 to 60 minutes, and most men go home the same day.
Is hydrocele surgery painful?
Most men feel soreness for a few days, which simple painkillers and snug support control well.
How long is the swelling after hydrocelectomy?
Swelling peaks in the first days and usually settles over 6 to 12 weeks.
Does hydrocele surgery affect fertility?
Rarely. Careful technique protects the epididymis, which matters most for men planning children.
Can the hydrocele come back after surgery?
It is uncommon after surgery, and more likely after needle drainage.
How much does hydrocele surgery cost in Turkey?
Assoc. Prof. Taş gives a personal written quote after the examination and ultrasound.
How long should I stay in Istanbul?
Plan about four to six days, plus a day or two if he also repairs a hernia.
