Hydrocele

A hydrocele (HI-droe-seel) is a type of swelling in the scrotum, the pouch of skin that holds the testicles.

A fluid-filled sac around a testicle, often first noticed as swelling of the scrotum.

Hydrocele is common in newborns and usually disappears without treatment within the first year. Older men can develop hydroceles, sometimes due to inflammation or injury.

Hydroceles are usually painless, but may become large and inconvenient. An ultrasound may be required to diagnose the condition.

Treatment usually involves watchful waiting. In rare circumstances, surgery is required.
