Congenital or primary communicating hydrocele arise in the peritoneum-vaginal canal. Through this canal and over time, the peritoneal cavity is in contact with the vaginal membrane of the testis. Under normal conditions, the peritoneum-vaginal canal closes before birth but when it does not close and the opening is small, only peritoneal fluid may pass, resulting in a hydrocele. Congenital hydrocele is more common in children. Secondary hydrocele arises from an imbalance between the lubricating fluid oozing from the testis and re-absorption by the vaginal membrane. In some circumstances, such as trauma or infection, but often without any apparent cause, the serous bag has difficulty reabsorbing the fluid. As a result, there is progressive accumulation of fluid inside the bag, resulting in a hydrocele. Secondary hydrocele is more common in adolescents and adults, although it may also occur in children.

This procedure is indicated for persistent hydrocele in the first six to twelve months of life.

The hydrocelectomy is a surgical procedure often performed to correct cases of hydrocele. The patient should wear a scrotal support for some time after surgery.

The doctor will indicate requirements, specific to each patient.

As with any surgery, it is always possible there are complications. In this type of surgery complications are possible but rare, there may occur infection or recurrence of the hydrocele.

After recovery from anaesthesia, the patient begins to drink fluids in small quantities and, if tolerated, may take a light meal. After an assessment of normal vital signs, the patient may be discharged and return home.

The patient should rest for one or two days at home before returning gradually to normal activities and avoiding the risk of accidents. The resumption of daily activities can take place four to seven days after discharge.
