Unilateral Blind Ending Ureter with Vesicoureteral Reflux and Associated Renal Agenesis -Multidetector Computed Tomography Imaging Findings.

A 50-year old woman was admitted to emergency room due to an episode of recurrent renal colic. Double-J ureteral stent has been placed several weeks earlier due to mild hydronephrosis of the left kidney. She had a history of urinary tract infections and poorly defined abdominal pain. Abdominal computed tomography (CT) scan revealed normal left kidney and normal left urinary tract without calculi, presence of double-J ureteral stent and absent right kidney (Figure 1 Coronal multiplanar reformatted image). Excretory phase of CT scan showed retrograde opacification of distal, blind-ending, nondilatated, nonobstructed right ureteral stump. Visualized structures suggested remnant of the incompletely developed right ureteral bud, with normal position of the right ureteral orifice (Figure 2A, Coronal curved-planar reformatted and
