title: Hydronephrosis secondary to a seminoma in abdominal cryptorchid testis.
abstract: 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. Despite the fact that he could not feel right testis since he was 7 years old, he had never looked for treatment. A huge mass was palpable in hypogastric, and IVP and CT Scan demonstrated functional exclusion of the right kidney, and a solid tumor localized at the right iliac fossa, near the bladder wall. The patient was submitted to laparotomy with resection of the mass, and the histopathologic study showed classic seminoma. Abdominal testes have higher incidence of malignancy than those in the inguinal position. The orchiopexy is recommended for abdominal testis after 2 years old to facilitate the investigation and identification of testicular cancer.
