Hydrocele Treatment (Hydrocelectomy)
A hydrocele is fluid collecting around the testicle — painless at first, but it keeps growing, and draining it with a needle only refills it. Our urologists treat it definitively with hydrocelectomy: a 30 to 45 minute daycare procedure through a small scrotal incision, with the sac dealt with so it cannot recur. Same-day discharge, back to desk work in 3–5 days, with cashless insurance.

What is Hydrocele?
A hydrocele is a collection of clear fluid in the space around the testicle. The testicle sits inside a two-layered sac called the tunica vaginalis, which normally contains just a few drops of fluid to let the testicle move smoothly. A hydrocele forms when that balance breaks down — either because too much fluid is produced or because too little is reabsorbed — and the sac fills up.
The result is a smooth, painless swelling of one side of the scrotum that grows slowly over months or years. Because it starts small and does not hurt, most men initially ignore it. It becomes a problem through sheer size: a large hydrocele can reach the volume of a grapefruit or larger, making walking awkward, sitting uncomfortable, clothing difficult and intercourse impractical. It also hides the testicle from examination, which matters, because a lump within the testicle cannot be felt through a tense fluid collection.
Hydroceles come in two forms. A communicating hydrocele occurs when the passage between the abdomen and the scrotum — the processus vaginalis — fails to close after birth. Abdominal fluid tracks down into the scrotum, which is why these characteristically change size through the day, being smaller in the morning and larger by evening. This type is seen in infants and children, is closely related to an inguinal hernia, and often resolves on its own in the first year or two of life. A non-communicating hydrocele has no such connection; it stays a constant size and is the usual adult form.
Most adult hydroceles are primary, with no identifiable cause beyond an imbalance between fluid production and absorption that becomes commoner with age. But a secondary hydrocele develops as a reaction to something else — infection such as epididymo-orchitis, injury, previous surgery, filariasis (still a significant cause in parts of India, and typically producing very large hydroceles), and, importantly, testicular tumours. This is precisely why a new hydrocele in a young man deserves an ultrasound rather than reassurance: a small proportion are the first sign of a testicular tumour hiding behind the fluid.
The classic clinical test is transillumination — a torch held against the scrotum in a darkened room lights the whole swelling up, because clear fluid transmits light while solid tissue and blood do not. It is a genuinely useful bedside test, but it does not replace an ultrasound, which is what actually confirms the testicle underneath is normal.
One thing worth stating plainly: aspiration alone does not work. Draining a hydrocele with a needle empties it temporarily and feels like a solution, but the sac remains, and it refills within weeks to months in nearly every case. Repeated aspiration also risks infection and bleeding, and can cause scarring that makes the eventual surgery harder. The only definitive treatment is surgery that deals with the sac itself — either everting it, plicating it or excising it — so there is no longer a cavity for fluid to collect in.

Signs you may need Hydrocele treatment
- Painless, smooth swelling of one side of the scrotum
- A swelling that has grown gradually over months or years
- A heavy, dragging sensation, worse by the end of the day
- Discomfort when walking, sitting for long periods or during intercourse
- Difficulty finding comfortable clothing as the swelling enlarges
- A swelling that lights up when a torch is held against it in a dark room
- Inability to feel the testicle separately from the swelling
- In children, a swelling that is smaller in the morning and larger by evening
- Sudden pain, redness or fever, suggesting infection or an underlying problem
- Rapid enlargement after an injury, which may indicate blood rather than clear fluid
What causes it?
- Imbalance between fluid production and reabsorption in the tunica vaginalis — the commonest adult cause
- Failure of the processus vaginalis to close after birth, producing a communicating hydrocele in infants
- Infection of the testicle or epididymis (epididymo-orchitis)
- Injury to the scrotum
- Filariasis, still an important cause in endemic parts of India and typically producing very large hydroceles
- Previous surgery in the groin or scrotum, including varicocele repair and hernia surgery
- Testicular tumour presenting with a reactive hydrocele
- Tuberculosis of the epididymis
Who is more likely to be affected
- Increasing age, particularly beyond 40
- Living in or having lived in a filariasis-endemic region
- Previous scrotal or groin surgery
- Previous episode of epididymo-orchitis or a sexually transmitted infection
- Prematurity in infants
- A history of inguinal hernia
- Injury or repeated trauma to the scrotum
When to see a doctor immediately
- Any new scrotal swelling, however painless
- A swelling that is enlarging, or one large enough to interfere with daily activity
- Sudden severe scrotal pain — this is an emergency and needs same-day assessment
- Pain, redness, warmth or fever alongside the swelling
- A hard lump felt within or alongside the testicle
- A hydrocele appearing in a young man, which needs an ultrasound to exclude a tumour
- Rapid swelling after an injury
- In a child, a swelling that persists beyond two years of age or is enlarging
How it is diagnosed
Clinical examination
The surgeon confirms the swelling is confined to the scrotum, that it is possible to get above it — which distinguishes a hydrocele from an inguinal hernia extending down — and assesses whether the testicle can be felt separately. Size, consistency and tenderness are recorded.
Transillumination
A torch held against the scrotum in a darkened room causes a hydrocele to glow, because clear fluid transmits light. A swelling that does not transilluminate suggests solid tissue, blood or a very thick-walled sac, and raises the priority of imaging.
Scrotal ultrasound
The definitive test, and one that should not be skipped. It confirms the fluid collection, measures its volume, and — most importantly — shows the testicle underneath clearly enough to exclude a tumour. Where the fluid is loculated or contains debris, it also points towards infection or an old bleed.
Tumour markers
Alpha-fetoprotein, beta-hCG and LDH are checked where ultrasound raises any suspicion of a testicular mass, particularly in a young man with a new hydrocele.
Urine and infection screen
Urine analysis and culture, and where relevant a screen for sexually transmitted infection, are done when the hydrocele is painful or has followed an episode of epididymo-orchitis.
Pre-operative assessment
Routine blood tests, coagulation profile, blood sugar and ECG for anaesthetic fitness before the procedure is scheduled.
How the options compare
| Feature | Needle Aspiration | Hydrocelectomy (Surgery) |
|---|---|---|
| What is done | Fluid drained with a needle | The sac itself is everted, plicated or excised |
| Anaesthesia | Local only | Spinal, general or local with sedation |
| Duration | 10–15 minutes | 30–60 minutes |
| Recurrence | Very high — refills in weeks to months | Under 5% |
| Definitive? | No, temporary relief only | Yes |
| Infection risk | Increases with repeated aspirations | Low, with a single procedure |
| Effect on future surgery | Repeated aspiration causes scarring that complicates it | Not applicable |
| Suitability | Patients medically unfit for any surgery | Almost all patients |
Types of treatment
Conservative management
Observation in infants
A communicating hydrocele in a baby usually resolves on its own as the processus vaginalis closes, typically within the first one to two years. Watchful waiting with periodic review is the correct approach, provided there is no hernia alongside it.
Observation in adults
Entirely reasonable for a small, painless hydrocele that is not enlarging, is not interfering with daily life, and where ultrasound has confirmed a normal testicle underneath. Not every hydrocele needs an operation.
Scrotal support
Supportive underwear or a scrotal suspensory relieves the dragging sensation in men with moderate hydroceles who are not yet opting for surgery.
Treating the underlying cause
Where the hydrocele is secondary to epididymo-orchitis or filariasis, treating that infection first may reduce the fluid — and in any case must precede surgery.
Definitive treatment
Jaboulay's procedure (eversion of the sac)
The commonest technique for a large hydrocele. Through a small scrotal incision the fluid is drained and the sac is turned inside out and stitched behind the testicle, so its secreting surface now faces outwards into tissue that absorbs the fluid. Effective, durable and the standard choice for thick-walled sacs.
Lord's plication
The sac is not excised or everted but gathered with a series of stitches so it bunches up close to the testicle, obliterating the cavity. Because there is minimal dissection, bleeding and haematoma risk are lower. Best suited to thin-walled, moderately sized hydroceles.
Excision of the sac
The sac is removed entirely. Used for very thick, calcified or chronically infected sacs where eversion or plication would not work. More dissection means a slightly higher risk of bleeding, so a drain is sometimes left for a day.
Aspiration with sclerotherapy
Fluid is drained and a sclerosant injected to obliterate the cavity. Reserved almost entirely for patients who are medically unfit for anaesthesia, because recurrence rates are higher and repeat sessions are often needed. It is not a first-line alternative to surgery.
Paediatric hydrocele repair
In children the approach is through the groin rather than the scrotum, because the problem is the open processus vaginalis rather than the sac itself. The connection is tied off, which is the same principle as a hernia repair.
What happens, step by step
- 1
Consultation and examination
20–30 minutes- The swelling is examined, transilluminated and distinguished from a hernia
- The surgeon checks whether the testicle can be felt separately
- Your symptoms, the rate of growth and how much it limits you are discussed
- You are told honestly whether observation is reasonable or surgery is the better course
- 2
Ultrasound and investigations
1–3 days- A scrotal ultrasound confirms the diagnosis and, crucially, shows the testicle is normal
- Tumour markers are checked if the scan raises any suspicion
- Routine blood tests, coagulation profile and ECG for anaesthetic fitness
- Any active infection is treated before surgery is scheduled
- 3
Admission and preparation
30–60 minutes- Admission on the morning of the procedure
- The surgeon confirms the side and marks it
- Consent is taken, the area is prepared and an IV line is started
- Prophylactic antibiotics are given
- 4
The procedure
30–60 minutes- Anaesthesia is given — spinal, general or local with sedation
- A small incision is made in the scrotum, or in the groin for a child
- The hydrocele sac is delivered and the fluid drained
- The testicle is inspected directly to confirm it is normal
- The sac is everted, plicated or excised so no cavity remains for fluid to collect in
- Bleeding points are secured carefully — this is what prevents a haematoma
- The wound is closed with absorbable sutures and a supportive dressing applied
- 5
Recovery room observation
2–4 hours- Vitals and the operative site are monitored as the anaesthesia wears off
- An ice pack and scrotal support are applied to limit swelling
- You are asked to pass urine and to walk before discharge
- 6
Discharge and follow-up
Same day- Most patients go home the same evening
- Painkillers, an anti-inflammatory and antibiotics are prescribed
- Ice, scrotal support and activity instructions are explained in writing
- Your free cab drops you home and a wound review is scheduled for the first week
How to prepare
- Complete the scrotal ultrasound before the surgery date is fixed — this is not optional
- Any active scrotal or urinary infection must be fully treated first
- Tell your surgeon about blood thinners, diabetes or heart medication
- Buy a scrotal support or snug supportive underwear to wear from the day of surgery
- Trim rather than shave the area, on the day before if instructed
- Fast for 6–8 hours before the procedure as instructed
- Arrange for an adult attendant to accompany you home
- Plan 3 to 7 days away from work and around three weeks away from the gym
Why patients choose this procedure
A permanent solution
Dealing with the sac itself removes the cavity in which fluid collects, so recurrence falls below 5% — against near-certain refilling after aspiration alone.
Relief from heaviness and dragging
The weight and dragging sensation that worsen through the day resolve, and walking, sitting and clothing all become comfortable again.
The testicle becomes examinable again
A large hydrocele hides the testicle from examination. Once the fluid is gone, the testicle can be felt and self-examined properly — which matters for detecting anything else early.
Direct inspection during surgery
The testicle is examined directly during the operation, providing certainty that no underlying abnormality has been missed behind the fluid.
Daycare procedure
Admission and discharge on the same day, through a small scrotal incision closed with absorbable sutures that need no removal.
Comfortable intercourse and activity
The practical limitations a large hydrocele imposes on exercise, intimacy and even choice of clothing resolve completely.
Possible risks and side effects
Scrotal swelling and bruising
Expected for two to four weeks, and often more than patients anticipate — the scrotum swells readily. Ice, scrotal support and avoiding prolonged standing all shorten it.
Haematoma
A collection of blood in the scrotum is the commonest complication of hydrocelectomy, which is why bleeding points are secured carefully and a drain is sometimes left overnight. Rapidly increasing, firm swelling should be reported at once.
Wound infection
Uncommon with prophylactic antibiotics and good hygiene. Increasing redness, discharge, spreading pain or fever should be reported without delay.
Recurrence
Under 5% after a properly performed hydrocelectomy, and much higher after aspiration or sclerotherapy. Recurrence is more likely with very large or chronically infected sacs.
Chronic scrotal pain
A small number of patients develop persistent discomfort in the scrotum after surgery. It usually settles over months, and is managed with analgesia and support.
Injury to the epididymis or vas deferens
Rare, but relevant for men who still wish to father children, since damage to the vas can affect fertility on that side. Careful dissection and identification of the structures is what prevents it.
What recovery looks like
Recovery after hydrocelectomy is straightforward, though the swelling lasts longer than most patients expect — and knowing that in advance prevents a lot of unnecessary worry.
First 48 hours: the scrotum will be swollen and bruised, sometimes markedly so. Use ice packs for 15–20 minutes several times a day, wear the scrotal support continuously including at night, and keep the legs elevated when resting. Take the prescribed painkillers on schedule rather than waiting for the pain to build.
Days 3 to 7: pain settles substantially and most patients with desk jobs return to work. Short walks are encouraged; prolonged standing is not. Keep the wound dry until your surgeon clears showering, and continue the scrotal support through the day.
Weeks 2 to 4: bruising fades and the incision heals, with absorbable sutures dissolving on their own. Some residual swelling is entirely normal at this stage and does not mean the hydrocele has recurred — this is the single most common source of alarm after this operation. Avoid heavy lifting, gym work and cycling.
Weeks 4 to 8: swelling resolves progressively and the final result becomes apparent. Gym, cycling and sport can restart at around three to four weeks, and sexual activity after two to three weeks on your surgeon's advice.
Contact your care coordinator immediately if you develop fever, rapidly increasing or firm scrotal swelling, severe pain, spreading redness, or discharge from the wound.
What to eat and what to avoid
Recommended
- Lean protein — eggs, fish, chicken, paneer, dal — to support wound healing
- Vitamin C rich fruit such as orange, guava, amla and lemon
- Zinc sources including pumpkin seeds, nuts and whole grains
- High-fibre foods to keep bowel movements easy and avoid straining
- Green leafy vegetables
- 2.5 to 3 litres of water a day
Best avoided
- Smoking and tobacco, which measurably slow wound healing
- Alcohol for the first week, particularly while on antibiotics
- Deep-fried and heavily processed food
- Excess salt, which worsens swelling
- Straining at stool, heavy lifting and gym work for the first three to four weeks
- Soaking in bathtubs or swimming pools until the wound is fully healed
- Prolonged standing in the first two weeks
Post-operative care, at no extra cost
- Diet and lifestyle consultation with a nutritionist
- Scheduled follow-up calls until you are fully recovered
- Free cab for the follow-up visit
- 24×7 access to your care coordinator for any concern
Hydrocele treatment cost
₹30,000 – ₹60,000
The range depends on whether one side or both are affected, the size of the hydrocele, whether an associated hernia or cyst needs dealing with in the same sitting, your city, the hospital and your room category. Hydrocele surgery is covered by almost all health insurance policies — our insurance desk checks your eligibility and files the cashless request before admission, at no charge.
Inside the care journey
Hydrocele — your questions answered
Not definitively. Draining the fluid with a needle empties the swelling temporarily and feels like a solution, but the sac remains and it refills within weeks to months in nearly every case. Repeated aspiration also raises the risk of infection and bleeding, and causes scarring that makes the eventual surgery harder. Sclerotherapy is reserved for patients medically unfit for any anaesthesia. Surgery that deals with the sac is the only reliable treatment.
