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.
RESULTS/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.
背景
一名64岁男性在对局限性肾细胞癌（RCC）进行随访期间出现无症状肉眼血尿，该患者6年前接受了右肾根治性切除术。
方法
X线检查和输尿管镜检查发现多个乳头状肿瘤充满右输尿管残端。手术切除输尿管残端和膀胱袖口。肿瘤组织学检查为2-3级移行细胞癌，无肌肉浸润。
结果/结论：肾切除术后发生输尿管残端癌的患者仅有4例报道，包括本病例。鉴于该患者有多种癌症病史，遗传或环境因素可能是输尿管残端肿瘤病因的一部分。
