Exams and Tests

Congenital hydroceles are diagnosed through a physical exam and a medical history. Because the swelling often is obvious, it is not difficult to diagnose. But care should be taken to ensure it is a hydrocele and not an inguinal hernia. The doctor will examine the scrotum and groin area to:

• Check for pain. Pain may indicate a hernia or an injury to the testicles.
• See if the swelling can be pushed back into the abdomen. If it can be, it may be a hernia.
• Try to feel above the swelling. If this is not possible, it may be a hernia.
• Shine a light at the scrotum. If the light does not shine through the swelling, it may be a hernia.

If your child has a hydrocele that varies in size (a communicating hydrocele), it may not be apparent during the visit. The doctor may ask if the swelling is less in the morning and then increases as the day goes on.

If an inguinal hernia or an abdominal-scrotal hydrocele (a rare hydrocele that extends from the scrotum into the belly area) is suspected, the doctor may order more tests, including an ultrasound.
