title: Primary tumor of the ureteral stump following a nephrectomy for renal cell carcinoma.
abstract: BACKGROUND
  A 64-year-old man presented with asymptomatic macroscopic hematuria during a follow up for a localized renal cell carcinoma (RCC), which was 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 the ureteral stump and bladder cuff. The tumor was histologically a grade 2-3 transitional cell carcinoma without muscle invasion.
  
  
  CONCLUSIONS
  Only four patients with a ureteral stump carcinoma, including the present case, have been reported after a nephrectomy for RCC. Considering that this patient had a past history of multiple cancers, genetic or environmental factors may have contributed to the etiology of the ureteral stump tumor.
