Blind-ending branch of bifid ureter: report of seven cases

Seven cases of bifid ureter with a blind-ending branch are presented: diagnosis was primarily made by excretory urogram. In 1 case the diagnosis was confirmed by retrograde pyelogram. The pelvicalyceal system showed ureteroureteral reflux into the blind-ending branch on photofluoroscopy and cineroentgenography. One rare case of blind-ending branch originating in the upper third of the ureter are described. The clinical aspects, roentgenographic findings, and treatment of these findings are reviewed.
