Prune belly syndrome is characterized by three findings:

• lack of abdominal musculature leading to "prune belly" appearance
• bilateral cryptorchidism
• urinary tract abnormalities

This patient was diagnosed with prune belly syndrome in the antenatal period with all of the above findings.

The patient did not have any urinary tract symptoms until this presentation when he presented with large hematuria. An MAG-3 scan was performed later which demonstrated a dysplastic right kidney providing 14% of overall renal function (left kidney - 86%).

The patient had previously been operated on for bilateral cryptorchidism.
