The occurrence of primary carcinoma of the ureteral stump following radical nephrectomy for renal cell carcinoma is extremely rare; 7 patients with the disease have been reported previously. All these patients were males with transitional cell carcinoma.
The current study reports the case of a 61-year-old woman, who presented with gross hematuria following a radical nephrectomy for local clear cell renal carcinoma. A computed tomography scan revealed the presence of a mass on the ureteral stump. The patient underwent a left ureteral stump and bladder cuff excision. The histological diagnosis was high-grade transitional cell carcinoma of the ureteral stump, with focal interstitial cancer cell infiltrates. There was no evidence of recurrence during a follow-up period of 35 months. In addition, the present study reviewed the literature for previous patients with ureteral stump carcinoma following a radical nephrectomy for renal cell carcinoma; 7 previous patients with the disease were identified. The present study suggests that, if patients who have previously undergone a radical nephrectomy for renal cell carcinoma present with hematuria, the possibility of ureteral stump carcinoma should be considered, particularly in East Asian countries. The existence or a history of bladder carcinoma should be considered as a high-risk factor for developing ureteral stump carcinoma. A ureteral stump and bladder cuff excision should be performed once ureteral stump carcinoma is diagnosed.
