A hydrocele is an accumulation of fluid around the testicles causing the scrotum to swell. This is caused due to non-closure of the tube through which the testicles descend into scrotum. Non-closure of the tube leads to accumulation of fluid in the scrotum. Inflammation or injury of the testicles, or blockage within the spermatic cord by fluid or blood may also cause hydrocele. This condition usually disappears after few months following birth. If the condition does not disappear, the child may develop hernia, where a section of the intestines runs through the still-opened pathway. If the child develops hernia minor surgery may be needed.
Hydrocele is most common in the new born infants. Individuals suffering from hydrocele may present with painless, swollen testicles feels like water balloon, occurring on one or both sides of testes.


Hydrocele is diagnosed by transillumination. This technique involves placing a small light source through the enlarged portion of the scrotum. If a hydrocele is present, the scrotum will light up. Also, an ultrasound can be done to detect presence of hydrocele in scrotum.


There are two types of hydroceles:

  • Communicating: They are present at birth. The hydroceles connect with the scrotum and abdomen.
  • Non-communicating: This condition may be present at birth or develop year’s later. There is no form of connection with the scrotum or abdomen.


Aspiration is alternate treatment option to drain out the fluid in scrotum. In this process, the fluid is removed using a needle. Risks associated with aspiration include infection, fibrosis, mild to moderate pain in the scrotum, and recurrence of hydrocele.

Surgery is done if hydrocele is large causing discomfort and cuts the blood supply to testicles.


Hydrocelectomy is a surgical procedure to treat a hydrocele and prevent its recurrence. The procedure is performed under general anesthesia. In infants, a small incision is made in the groin (area where the upper thigh meets the trunk), and in adults the incision is made on the scortum. The fluid is drained after removing the part of the sac. Incision is closed with dissolvable stitches.

Sometimes a laparoscope is used for this procedure. A Laparoscope is a tube-like instrument having a tiny camera at the end of the tube. A camera is attached to the monitor to display larger images of the procedure. Small surgical instruments are inserted through the other incisions and repair or removal is done.
