[Ureteral stump metastasis from renal cell carcinoma: a case report].
A case of ureteral metastasis from renal cell carcinoma is reported. A 71-year-old man who had received radical nephrectomy for left renal cell carcinoma, G1 and about two years earlier presented with asymptomatic macrohematuria. He had received interferon therapy and surgical treatments for bone metastasis two times after the operation. Cystoscopic examination revealed bleeding from the left residual ureter but CT scan showed no abnormal findings. Left ureterectomy and partial cystectomy was performed and a small finger tip-sized tumor was found at 13.5 cm above the ureteral orifice. Pathological examination showed metastatic renal cell carcinoma, G1 > G2. Histologically and clinically, this tumor seemed to have metastasized by a hematological pathway. Seventeen cases of ureteral metastasis of renal cell carcinoma have been reported previously in the Japanese literature.
