title: [A case of left pelvic kidney with non-functioning hydronephrosis].
abstract: A 19-year-old male was admitted with left lower abdominal pain and dysuria. Excretory urograms showed only a right kidney. V.C.G. showed a cystic mass lesion over the bladder. Computerized tomography revealed a huge retroperitoneal cystic mass located near the bladder. It seemed to be a huge bladder diverticulum, but the diagnosis was not clearly confirmed before operation. Through a lower abdominal midline incision, the cystic mass structure was removed. The specimen was a left ectopic pelvic kidney with non-functioning hydronephrosis. The removed mass was 91 X 85 X 78 mm in size, and 120 g in weight. The intrarenal fluid was 350 ml. A brief discussion and review are made. To our knowledge, only 3 such case have been described in the Japanese literature.
