The patient was evaluated by abdominal computed tomography (CT) and intravenous pyelography (IVP), which revealed incomplete duplication of the left urinary system with lower pole moiety hydronephrosis (Figures 1 and 2).
CT shows hydronephrosis of the left lower-pole.

The patient was evaluated by abdominal computed tomography (CT) and intravenous pyelography (IVP), which revealed incomplete duplication of the left urinary system with lower pole moiety hydronephrosis (Figures 1 and 2).
RP reveals UPJO of the left lower-pole in the incomplete duplicated system.

Retrograde pyelography (RP) showed ureteral stenosis close to UPJ with severe hydronephrosis of the lower pole moiety (Figure 3).
Contrast leakage from the upper-pole of the incomplete duplicated collecting system after the inflation of the UPJO, and stents were placed to the upper-pole and lower-pole.

However, there was urinary leakage with contrast from the upper-pole at the dilated ureteral stenosis lesion, and another ureteral stent (same size and same company) was inserted to the upper-pole of the collecting system (Figures 4 and 5) just after the balloon dilatation.
CT shows contrast leakage in the retroperitoneal space.

However, there was urinary leakage with contrast from the upper-pole at the dilated ureteral stenosis lesion, and another ureteral stent (same size and same company) was inserted to the upper-pole of the collecting system (Figures 4 and 5) just after the balloon dilatation.
IVP shows the improvement of the hydronephrosis of the left lower-pole 3 months postoperatively.
