Synchronous tumors in both ureters and left renal pelvis.

A case of bilateral, synchronous ureteral tumors and a tumor in the left renal pelvis is presented. Conservative surgical treatment involved local resection of both ureteral tumors and partial nephrectomy of the left kidney. Multiple urothelial tumors subsequently developed in the bladder which were resected. The patient has had good kidney function and no evidence of disease.
