Blind-ending ureteral duplication: Cause of asymptomatic abdominal mass

Gastric, pancreatic, and ureteric duplication

“…[9] Blind-ending inverted Y duplications may arise as a result of abnormal canalization of the ureteral bud, absorption of the common stem of the mesonephric duct into the bladder, or fusion of two ureteral buds before joining the metanephric blastema. [10] Such duplications may be connected to the urinary tract only by fibrous cords,[10] or their communication with the urinary tract may be totally lost. [8] In these cases, the diagnosis of the ureteric duplication is not possible by intravenous pyelography or retrograde studies and a nonenhancing mass is seen on CECT scan.…”

Resection of Blind Ending Bifid Ureter in a Patient with Grade V Vesicoureteric Reflux

“…The most common symptoms include recurrent urinary tract infection, flank pain and haematuria. It has been reported with a female predominance of three to one and occurring twice as often on the right side (2,3). In this case report we present a male patient with a previous diagnosis of right duplicated ureter who had undergone a bilateral ureteroneocystostomy for vesicoureteral reflux (VUR) in another clinic.…”

“…HUN, renal colicky pains, or even an acute abdomen (2,3,4). KAWAMURa and SASAKI reported a case with transitional cell carcinoma in the blind-ending branch of the bifid ureter (5).…”

“…The diagnosis is most commonly made by IVP with oblique views showing the blind-ending segment filled by retrograde uretero-ureteral reflux. Retrograde pyelography enables one to visualize the blind-ending ureter (2,3,4). During the revision of the present patient, the diagnosis of BEBU could be established only by catheterization of each of the ureteric orifices and by obtaining retrograde pyeolograms.…”

“…It appears to be more common in females (1,2,3,4). There are approximately 200 case reports published in the related literature (4).…”
