Frequently Asked Questions About Hydrocele

What is a hydrocele?

A hydrocele is a fluid-filled sac around a testicle.

How does a hydrocele manifest?

A hydrocele typically appears as a unilateral swelling in the scrotum. The diagnosis is made either through a doctor's examination and/or with the help of an ultrasound. The swelling consists of fluid accumulation between the various tissue layers around the testicles and epididymis. In children, a hydrocele occurs because the peritoneum has not closed in the groin, allowing fluid from the abdomen to accumulate in the scrotum.

When should you seek immediate medical attention?

If swelling in the scrotum reappears, it is important to rule out testicular cancer, particularly in younger men (under 35 years of age). If you notice a new lump or swelling, make an appointment with your doctor as soon as possible.

When should you consider treatment?

A hydrocele is completely harmless and may not always require treatment. Reasons to treat a hydrocele include discomfort, skin irritation, or if the swelling interferes with sexual activity.

How is a hydrocele treated?

A hydrocele can either be treated with surgery under local anesthesia or general anesthesia or by puncturing it. In surgery, the scrotum is opened, and all fluid is drained. If it is a spermatocele, the majority of the fluid-containing membranes are removed. Bleeding is carefully controlled to prevent bleeding in the scrotum after the operation. The skin of the scrotum is closed with dissolvable stitches. In puncturing, the fluid is drained with a needle, and tissue adhesive is injected into the space where the fluid was. The risk of recurrence is higher with puncturing than with surgery.

What should be considered after the surgery?

You may often feel pressure-induced pain in the first few days after the surgery. Pain is usually relieved with over-the-counter pain medication. If you notice fever, increased swelling, or pain, contact us. Avoid sexual intercourse and swimming for the first week. It is fine to shower the day after the surgery. It is common for the scrotum to remain swollen for several weeks after the surgery.

What complications can occur after surgery?

Complications from the surgery can include infection in the area and bleeding. If you notice signs of complications, contact us or your nearest emergency department.
