Hydronephrosis secondary to a seminoma in abdominal cryptorchid testis.

The incidence of testicular cancer in cryptorchidism is 30 to 50 times higher than in general population. We present a case of hydronephrosis caused by a seminoma in an abdominal cryptorchid testis. A 22 years old male presented abdominal and right flank pain, and haematuria.
