Primary tumor of the ureteral stump following a nephrectomy for renal cellcarcinoma

Background: A 64-year-old man presented with asymptomatic macroscopic hemat uria during a follow up for a localized renal cell carcinoma (RCC), which w as treated by a right radical nephrectomy 6 years earlier. Methods: X-rays and a ureteroscopic examination revealed multiple papillary tumors filling the right ureteral stump. Surgery was performed to excise t he ureteral stump and bladder cuff. The turner was histologically a grade 2 -3 transitional cell carcinoma without muscle invasion. Results/Conclusions: Only four patients with a ureteral stump carcinoma, in cluding the present case, have been reported after a nephrectomy for RCC. C onsidering that this patient had a past history of multiple cancers, geneti c or environmental factors may have contributed to the etiology of the uret eral stump tumor.
