Sudden severe scrotal pain is not a routine hydrocele symptom
Seek Urgent Medical Care If
- Scrotal or testicular pain begins suddenly, is severe, or is accompanied by nausea or vomiting.
- A groin or scrotal swelling becomes hard, very tender, irreducible or rapidly larger.
- You develop fever, chills, confusion, rapidly spreading redness or dark or blistered scrotal skin.
- After surgery, swelling expands rapidly, the dressing becomes repeatedly soaked with blood or you feel faint.
- You cannot pass urine, the wound opens widely, or postoperative pain and swelling worsen markedly rather than settling.
Testicular torsion, a trapped inguinal hernia, severe infection or postoperative bleeding needs urgent medical assessment. Do not assume that every painful scrotal swelling is caused by the known hydrocele.
What Is Hydrocelectomy?
A hydrocele is fluid around a testicle, collected within the tunica vaginalis sac. During hydrocelectomy, the surgeon drains this fluid and alters the lining of the sac so that it is less able to fill again.
The testicle is not intentionally removed. The operation is different from aspiration, which only withdraws fluid through a needle and leaves the fluid-producing space present.
A hydrocele is a finding—not always the whole diagnosis
Before surgery, the clinician must be satisfied that the swelling is fluid and that the testicle, epididymis and groin have been assessed for testicular tumour, infection, hernia or another cause.
When May Hydrocelectomy Be Recommended?
Increasing size
The hydrocele continues to enlarge or becomes tense and difficult to examine.
Heaviness or discomfort
Dragging, pressure, skin irritation or discomfort interferes with walking, sitting, work or exercise.
Daily-life difficulty
Clothing, hygiene, sleep, sexual activity or mobility becomes troublesome.
Diagnostic uncertainty
The testicle cannot be examined adequately or another scrotal condition must be excluded.
Persistent childhood hydrocele
A communicating or longstanding hydrocele does not resolve within the age-appropriate observation period.
Associated hernia
A patent passage permits abdominal contents as well as fluid to enter the groin or scrotum.
A small, stable, painless adult hydrocele does not automatically require surgery. The decision should reflect symptoms, examination, ultrasound findings, health, anaesthetic risk and patient preference.
What Must Be Confirmed Before Surgery?
Adult and Childhood Hydrocele Repair Are Different
Timing for children varies with age, whether the swelling communicates, the presence of a hernia, prematurity and local paediatric-surgery practice. A child should follow an individual surgical plan rather than an adult hydrocelectomy pathway.
Are There Alternatives to Hydrocelectomy?
Repeated drainage without reassessment can delay diagnosis of another scrotal condition. Aspiration should not be treated as routine do-it-yourself or cosmetic fluid removal.
What Happens Before the Operation?
- The diagnosis, side, size, symptoms and examination or ultrasound findings are reviewed.
- Any suspected tumour, infection, hernia or acute scrotal condition is evaluated before elective repair.
- The surgical team reviews regular treatment, allergies, bleeding history and previous groin or scrotal operations.
- Fasting and admission instructions depend on the planned anaesthetic and must follow the hospital’s individualized directions.
- Consent includes the incision, expected swelling, lasting bulkiness, recurrence, fertility-related structures and possible drain placement.
What Happens During Adult Hydrocelectomy?
What Do Lord, Jaboulay and Excision Techniques Mean?
Plication
The sac is folded or bunched with stitches around the testicle. This is often called a Lord-type repair.
Eversion
The sac is opened and turned behind the testicle so the fluid-producing surfaces no longer face each other. This is often called a Jaboulay-type repair.
Partial excision
Part of a large or thick sac is removed and the remaining edges are controlled carefully.
No single technique is best for every hydrocele. Size, wall thickness, inflammation, previous surgery, bleeding risk and surgeon experience guide the choice.
What Happens During Childhood Communicating Hydrocele Repair?
The operation is generally performed under general anaesthesia. Through a small groin incision—or a selected laparoscopic approach—the surgeon identifies the patent processus vaginalis, separates it carefully from the vas deferens and testicular blood vessels, and closes it near the abdomen. Scrotal fluid is released.
If an inguinal hernia is present, abdominal contents are returned safely and the hernia sac is repaired. The opposite side may be assessed in selected laparoscopic cases, but management is individualized rather than automatic.
Will a Drain Be Needed?
Many straightforward hydrocelectomies do not require a drain. A surgeon may place one when the hydrocele is very large, the sac is thick or inflamed, bleeding risk is increased or there is concern about postoperative fluid accumulation.
A drain does not mean that the operation failed. Its purpose, expected output and removal plan should be explained before discharge. A drain that stops working while swelling or pain increases requires assessment.
What Should I Expect During Recovery?
- Scrotal swelling, bruising and discomfort are expected and may remain noticeable for several weeks.
- The operated side often feels bulkier than the unaffected side because tissue and the repaired sac remain around the testicle.
- Absorbable stitches commonly loosen and disappear as the wound heals.
- A supportive garment may be provided or recommended as part of the individual discharge plan.
- Work, driving, lifting, exercise and sexual activity should resume according to comfort, wound healing, anaesthesia recovery and the surgeon’s instructions.
- The final size and feel should not be judged during the first postoperative days.
Early Swelling Is Not the Same as Recurrence
Bruising, tissue oedema, a small blood collection and the folded sac can make the scrotum look enlarged soon after surgery. True recurrent hydrocele is assessed after healing and, when uncertain, with examination or ultrasound.
Postoperative symptoms that need direct review
Contact the Treating Team Urgently If
- The scrotum enlarges rapidly, becomes very tense or pain escalates suddenly.
- Bleeding continues or repeatedly soaks the dressing.
- Fever, chills, spreading redness, foul discharge or increasing wound heat develops.
- The testicle or scrotal skin becomes unusually pale, dark, cold or progressively numb.
- You cannot pass urine, feel faint or unwell, or develop persistent vomiting or breathlessness.
- A drain comes out unexpectedly, stops draining with increasing swelling or produces an unexpected amount of fresh blood.
Possible Risks and Limitations
Can Hydrocelectomy Affect Fertility or Sexual Function?
A hydrocele itself usually surrounds rather than destroys the testicle, and hydrocelectomy does not intentionally involve the erectile organs. Erections, ejaculation and sexual function are generally preserved after recovery.
The epididymis, vas deferens and testicular blood vessels lie close to the operative field. Injury is uncommon but can affect fertility or testicular function, particularly with bilateral surgery, previous infection or surgery, a solitary functioning testicle or pre-existing fertility concerns. These factors should be discussed before consent.
What Does Successful Hydrocele Repair Mean?
Success means the troublesome fluid collection has been treated, the testicle and surrounding structures are protected, healing is acceptable and symptoms improve. It does not mean that both sides will feel perfectly identical or that every postoperative lump disappears immediately.
A stable residual bulk from the repaired sac is different from a recurrent fluid collection. Persistent enlargement, new firmness, increasing pain or a change after initial recovery requires reassessment rather than assumption.

Common Myths
Frequently Asked Questions
Is hydrocelectomy always necessary?
No. Observation is often appropriate when an adult hydrocele is small, stable and not troublesome or when an infant hydrocele is likely to resolve.
Why is ultrasound sometimes performed before surgery?
Ultrasound can confirm fluid, assess the testicle and epididymis, and look for tumour, inflammation, hernia or another cause when examination is limited or uncertain.
Is the testicle removed?
No. Hydrocelectomy repairs the sac around the testicle. Testicle removal is a different operation and is not part of routine hydrocele repair.
What anaesthesia is used?
Adult surgery commonly uses general or spinal anaesthesia. Childhood repair is usually performed under general anaesthesia. The plan is individualized.
Where is the incision?
Adult non-communicating hydroceles are usually approached through the scrotum. Communicating childhood hydroceles are generally repaired through the groin or selected laparoscopic access.
What is done to the hydrocele sac?
After draining the fluid, the surgeon may plicate, evert or partly excise the sac depending on its size, wall thickness and surrounding tissues.
Will I need a drain?
Not always. A drain may be used for a very large, thick-walled or inflamed hydrocele or when bleeding or fluid accumulation is a concern.
How long will swelling last?
Bruising and swelling may remain for several weeks. Large hydroceles and haematomas can take longer to settle.
Why does the testicle still feel bulky?
The repaired sac and postoperative tissue swelling remain around the testicle. The operated side may never feel identical to the unaffected side.
Can the hydrocele return?
Yes. Recurrence is uncommon after definitive repair but remains possible, especially when anatomy or underlying disease is complex.
Does aspiration cure a hydrocele?
Usually not. It removes fluid temporarily but leaves the sac intact, so re-accumulation is common and infection or bleeding can occur.
Can hydrocelectomy affect fertility?
Fertility is usually preserved, but uncommon injury to the epididymis, vas deferens or testicular blood supply can matter, especially with bilateral or pre-existing disease.
Can a baby’s hydrocele disappear without surgery?
Many infant hydroceles resolve as the developmental connection closes. Persistence, communication, symptoms or an associated hernia changes the timing of repair.
When is a hydrocele an emergency?
A painless uncomplicated hydrocele is not usually an emergency. Sudden severe pain, vomiting, a hard irreducible swelling, fever or dark skin could indicate torsion, trapped hernia or infection.
When is higher-centre referral appropriate?
Complex childhood anatomy, recurrent or giant hydrocele, suspicious tumour, severe filarial disease, previous extensive groin surgery, a solitary functioning testicle or major anaesthetic risk may need specialist care.
