A hydrocele occurs when fluid collects in the scrotum and causes it to swell. This may or may not be accompanied by a hernia. A hernia is present when bowel or membranes, known as omentum, push through the abdominal wall either into or above the scrotum. A hydrocele or a hernia may be on one or both sides. These conditions can occur when the opening between the abdomen and the scrotum do not close after birth.
How often do these conditions occur?
- Hernia or hydrocele occurs in 3-5 percent of
full-term infants
- Hernias usually occur in newborns but may appear weeks, months or years after birth
- Prematurity and low birth weight can increase the chance for a hernia or hydrocele

Hydroceles appear as swelling in the scrotum. A hydrocele may appear larger at the end of the day or with increased activity. Hernias appear as a bulge in the groin.
Our approach to treating a hydrocele or hernia
A hydrocele that persists beyond 12 months of age usually requires a surgical correction. A hernia at any age should be corrected. The surgery involves making a small incision in the groin or inguinal area and then draining the fluid and closing off the opening between the scrotum and the abdominal area.
