Blind-ending duplications of ureter

Blind-Ending Bifid Ureter with an Intravesical Ectopic Orifice

“…In the case of two ureteral orifices, multiple bud ding of the Wolffian duct leads to duplex ureters [9,12,14], For unclear reasons, there seems to be no union of one ureteral bud with the metanephric blastema in utero, resulting in a blind bifid ureter or a blind duplex ureter. In the past some short blind-end ing duplications have been classified as ureteral diverticula causing considerable confusion in terminology [4], but most of these cases could be defined as blind-ending ureters rather than diverticula [3,9,12], [15] distinguished four types of blind ending ureteral duplications ( fig. 6).…”

“…Complete or incomplete ureteral duplications as the most com mon congenital anomaly of the ureter may be familial [7,12,15] and the position of the ureteral orifices within the trigone is suggestive of possible dysplasia in an upper segment [11] (fig. 5).…”

“…In small children, like our case, this can be done through a single suprainguinal incision and, once again the psoashitch technique proved to be a reliable method of ureteroneocystostomy [6]. [15].…”
