[Intestinal obstruction caused by transitional carcinoma].
OBJECTIVES: To draw attention to the possibility that distant intestinal metastasis can arise from transitional urothelial carcinoma located in the bladder. METHODS: Two female patients developed distant metastasis during treatment of the tumor by transurethral resection of the bladder. RESULTS: Following complicated transurethral resection with perforation of the peritoneal cavity, the patients developed intestinal obstruction from metastatic transitional cell carcinoma. CONCLUSIONS: Direct or distant seeding of tumor cells on previously undamaged peritoneal serosa produced with the resectoscope may not be exceedingly unlikely.
