title: [Carcinosarcoma of the renal pelvis and ureter: a case report].
abstract: We report a case of carcinosarcoma of the renal pelvis and ureter arising in an 89-year-old man who presented at our hospital with gross hematuria. Abdominal computed tomography, excretory pyelography, and retrograde pyelography demonstrated that left hydronephrosis was caused by an ureteral tumor. Left urine cytology indicated transitional cell carcinoma. The patient underwent chemotherapy and radiation therapy. However, gross hematuria recurred, and the patient underwent left nephroureterectomy. The surgical specimen showed carcinosarcoma in the renal pelvis and ureter histologically. He has been free of cancer for 1.5 years.
