title: [Squamous cell carcinoma of the ureter as a late complication of ureterocutaneostomy--a case report].
abstract: 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.
