A case of renal cell carcinoma associated with synchronous contralateral renal pelvic cancer and bladder tumor.

We report a case of renal cell carcinoma associated with synchronous contralateral renal pelvic cancer and bladder tumor. The patient underwent total nephroureterectomy for the left renal pelvic cancer with transurethral resection of the bladder tumor. After 2 courses of combination chemotherapy, we performed surgical enucleation of the right renal cell carcinoma. Although transurethral resection of the recurrent bladder tumors was undergone 17 months after the last operation, the patient retains normal renal function.
