Ureteral stenosis following iliac artery stenting

Ureteral complications after open aortoiliac reconstruction for aneurysmal and occlusive disease have been reported previously. However, ureteral complications from endovascular interventions for iliac artery disease are relatively rare. We describe a case of left ureteral stenosis resulting in hydroureteronephrosis after multiple endovascular interventions involving the left common and external iliac arteries. The intraoperative findings during robotic ureterolysis revealed significant peri-iliac fibrosis and scarring in the area of the iliac stents. This case illustrates that, although uncommon, ureteral stenosis may occur after iliac stenting owing to peristent fibrosis.
