Hydrocele refers to fluid that builds up between the layers (tunics) surrounding the testicle.
It may be caused by:
- testicular or epididymal tumor
- following a surgical varicocele repair
Hydrocele may be of unknown etiology (idiopathic)
Typically, the patient’s medical history and a clinical examination by the urologist are sufficient.
However, additional tests may be required, such as an ultrasound, to confirm the diagnosis and rule out other conditions resulting in the enlarged scrotum.
When hydrocele is enlarged and causes discomfort, it is surgically treated via a scrotal incision.
