Abstract

A case of renal cell carcinoma in a L-shaped kidney was reported. The patient was a 60-yearold man who came with the chief complaint of gross hematuria and lower abdominal pain. Drip infusion intravenous urography demonstrated a L-shaped kidney with filling defect in the left renal pelvis. On admission he received several urological examinations. Abdominal aortography and CT-scanning revealed malignant tumor mainly in the left kidney of the fused L-shaped kidney. We diagnosed as above preoperatively and performed construction of subcutaneous blood access for hemodialysis and bilateral nephrectomies and ureterectomies. Histological diagnosis was renal cell carcinoma of clear cell type. And the additional therapy of Hysron (medroxyprogesteron acetate) (150 mg/day) was performed pre- and postoperatively. There was no reported case of the tumor in a L-shaped kidney in]apan, though 22 cases of tumor in horseshoe kidneys have been reported.
