Bifid blind-ending ureter

Six patients with bifid blind-ending ureter diagnosed at excretory urography are presented. In four of six patients the blind ureter was an incidental discovery. All had a characteristic appearance on urography consisting of an elongated contrast-filled tubular structure which usually terminated in a bulbous proximal tip. Demonstration of the rounded tip at excretory urography is important as it indicates the entire blind ureter has been opacified, obviating the need for retrograde pyelography.
