Hydrocele repair
HydrocelectomyHydrocele repair is surgery to correct the swelling of the scrotum that occurs when you have a hydrocele. A hydrocele is a collection of fluid around a testicle.
Scrotum
The scrotum is a part of a male's body that is located below the penis. The scrotum is the sac (pouch) that contains the testes, epididymis, and the...

Baby boys sometimes have a hydrocele at birth. Hydroceles also occur in older boys and men. Sometimes they form when there is also a hernia (an abnormal bulging of tissue) present. Hydroceles are fairly common.
Description
Surgery to repair a hydrocele is often done at an outpatient clinic. General anesthesia is used so you will be asleep and pain-free during the procedure.
In a baby or child:
- The surgeon makes a small surgical cut in the fold of the groin, and then drains the fluid. The sac (hydrocele) holding the fluid may be removed. If needed, the surgeon strengthens the muscle wall with stitches. This is called a hernia repair.
Hernia repair
Inguinal hernia repair is surgery to repair a hernia in your groin. A hernia is tissue that bulges out of a weak spot in the abdominal wall. Your i...

A laparoscope is a tiny camera that the surgeon inserts into the area through a small surgical cut. The camera is attached to a video monitor. The surgeon makes the repair with small instruments that are inserted through other small surgical cuts.
In adults:
- The cut is most often made on the scrotum. The surgeon then drains the fluid after removing part of the hydrocele sac.
Needle drainage of the fluid is not done very often because the problem will always come back.
Why the Procedure Is Performed
Hydroceles often go away on their own in children, but not in adults. Most hydroceles in infants will go away by the time they are 2 years old.
Your surgeon may recommend hydrocele repair if the hydrocele:
- Becomes too large
- Causes problems with blood flow
- Is infected
- Is painful or uncomfortable
The repair may also be done if there is a hernia associated with the problem.

During the week before your surgery:
- You may be asked to temporarily stop taking medicines that keep your blood from clotting. These medicines are called blood thinners. This includes over-the-counter medicines and supplements such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), and vitamin E. Many prescription medicines are also blood thinners.
- Ask your surgeon which medicines you should still take on the day of surgery.
- Let your surgeon know about any illness you may have before your surgery. This includes COVID-19, a cold, flu, fever, herpes breakout, or other illness. If you do get sick, your surgery may need to be postponed.

After the Procedure
Recovery is quick in most cases. Most people can go home a few hours after surgery. Children should limit activity and get extra rest in the first few days after surgery. In most cases, normal activity can start again in about 4 to 7 days.
Outlook (Prognosis)
The success rate for hydrocele repair is very high. The long-term outlook is excellent. However, another hydrocele may form over time, especially if a hernia was present.

Hydrocele - illustration
A hydrocele is a collection of fluid inside the area of the scrotum, surrounding the testicle. Hydroceles are common in newborn infants and normally resolve after a few months after birth. The main symptom is a painless, swollen testicle, on one or both sides, which feels like a water-filled balloon. Hydroceles are usually not dangerous, and they are usually only treated when they cause discomfort or embarrassment, or they get so large that they threaten the blood supply of the testicle.
