Ureteral triplication.

A case of ureteral triplication is presented. There was reflux of the middle ureter, which did not end in the kidney, but rather ended blindly. There was atrophic pyelonephritis of the upper pole because of an obstructed ureter, and a normal lower caleceal system and ureter. There were three ureters but only two originated in the kidney and two entered the bladder, with only one ureter originating from the kidney entering the bladder normally. The refluxing ureter and the obstructed upper pole and ureter were removed.
