Pelvioureteric junction obstruction of the lower collecting system associated with incomplete ureteral duplication: A case report

In cases with incomplete ureteric duplication, lower pole ureteropelvic junction obstruction (UPJO) may occur as an unusual entity. Surgical reconstruction of UPJO can be with different techniques such as pyeloplasty, pyeloureterostomy or ureteroureterostomy. In our case, the connecting segment distal to the pelvioureteric junction was found short and we performed direct pyeloureteral side-to-side anastomosis, with a double j catheter. It is helpful to determine prior to reconstruction of a short lower pole ureteral length.
