A case of squamous cell carcinoma of the ureter was reported. A 62-year-old woman, who underwent left nephrectomy and right ureterocutaneostomy at the age of thirty-one because of tuberculosis of the urinary tract, visits our hospital periodically for an ureteral catheter change. An urgent nephrostomy was performed because of ureteral stricture on March 8, 1994. Three months later tenderness and induration appeared at the former ureteral stoma. The resected specimen was histologically diagnosed as squamous cell carcinoma. Right palliative ureterectomy did not produce the desired effects due to the invasion of the tumor into the surrounding organs. In this rare case, it is suggested that chronic infection and irritation of the indwelling catheter might be causative of squamous cell carcinoma of the ureter.
报告了一例输尿管鳞状细胞癌病例。一名62岁女性，31岁时因泌尿系统结核接受了左肾切除术和右输尿管皮肤造口术，定期来我院更换输尿管导管。1994年3月8日因输尿管狭窄进行了紧急肾造口术。三个月后，原输尿管造口处出现压痛和硬结。切除标本经组织学诊断为鳞状细胞癌。由于肿瘤侵犯周围器官，右侧姑息性输尿管切除术未达到预期效果。在这个罕见病例中，提示留置导管的慢性感染和刺激可能是输尿管鳞状细胞癌的病因。
