Background
A hydrocele is a collection of serous fluid that results from a defect or irritation in the tunica vaginalis of the scrotum. Hydroceles also may arise in the spermatic cord or the canal of Nuck. A communicating hydrocele is similar to a hernia except that the sac connecting the abdomen to the scrotum or labia majora contains only fluid rather than abdominal contents. A noncommunicating hydrocele is a collection of scrotal fluid that is isolated from the abdomen. Noncommunicating hydroceles are the most common type of hydrocele globally, affecting more than 30 million men and boys
