Hydrocele surgical procedure

What is hydrocele?

Secondary hydrocele consists of a collection of fluid in the scrotal sac, between the impermeable sheets of the tunica vaginalis, which lines the testis and epididymis, and the serosa lining the scrotal sac.  Due to inflammatory, degenerative, or traumatic events, serous fluid is produced in the cavity, distending it to a size that restricts movement of the thighs or wearing of clothing. As inflammation persists, the conspicuous amount of endo-scrotal fluid is maintained.

Diagnosis of Hydrocele

The diagnosis of hydrocele is made by palpation and transillumination of the scrotum. However, a scrotal ultrasound is recommended to visualize the testis, which may be affected by degenerative phenomena and thus be the cause of the hydrocele.

Surgery for eversion of the tunica vaginalis of the testis

The surgery consists of a unilateral hemiscrotal transverse incision or median incision in the case of bilateral hydrocele and the subsequent removal (eversion) of the parietal leaflet. In this way, the fluid produced by the remaining leaflet is then reabsorbed by the tissues, as there is no longer an impermeable membrane. The procedure can be performed under local anesthesia and its duration is approximately 30 minutes.


The sutures will not have to be removed, but that they too will be made of resorbable material and will fall out on their own. After the surgery, it is recommended not to do any physical exertion for about 7 days. Sports activities can be resumed about 1 month after surgery.

Benefits from the surgery

The benefits resulting from the surgery are:

  • resolution of the hydrocele;
  • less discomfort during physical activity.

However, there is a possibility, although rare, that the hydrocele will reform.

Complications and/or risks related to the surgery

Possible complications and/or risks related to the surgery are:

  • endo-scrotal bleeding and hematomas;
  • infection of the surgical wound and testicle (orchi-epididymitis). If the hematoma enlarges, surgical reoperation is necessary.
  • Traction pain of the hips months later.
