What is a Hydrocele?
A hydrocele is a fluid-filled sac in the scrotum that causes swelling, affecting one or both sides. It’s more common in infants but can also occur in adults.
Types of Hydroceles
- Communicating Hydrocele: Fluid flows from the abdominal cavity into the scrotum due to an open connection (processus vaginalis). Swelling may change size throughout the day.
- Noncommunicating Hydrocele: No connection to the abdominal cavity, but fluid remains around the testicle. It may develop at birth or later in life.
Symptoms
- Scrotal swelling (feels like a water balloon)
- Discomfort or pain
- Heaviness in the scrotum
- Swelling size may vary during the day
Causes
Hydroceles often result from incomplete closure of the processus vaginalis during fetal development.
Who Is Affected?
Hydroceles are common in 10% of newborns and usually resolve within a year. Only 1% of adults develop hydroceles, which often disappear without treatment.
