[Blind-ending bifid ureter: a case report]

This is a report on a case of blind-ending ureter. The patient was a 56-year-old female who had complained of a pain in the left flank. There was no urinary tract infection. Excretory urography revealed a left blind-ending bifid ureter. It was resected and the removed specimen was about 8 cm in length. Histologically, it had all layers of the ureteral structure, but no renal tissue was found. The post-operative course was uneventful. We collected 55 cases of blind-ending bifid ureters reported in Japan including our own and discussed the difference between blind-ending bifid ureter and ureteral diverticulum.
