AUA 2016: Ureteral strictures after ureteroscopy for nephrolithiasis: Multi-Institutional Outcomes - Poster Session Highlights

San Diego, CA USA ( Ureteroscopy is commonly performed on patients with renal and/or ureteral calculi. Although uncommon, there is small risk for ureteral stricture in patients after an ureteroscopy is performed and treatment outcomes may vary.

To evaluate these risks, Dr. May and colleagues performed a retrospective review of patients with ureteral strictures related to ureteroscopy and presented their findings in this moderated poster.

From 2006 to 2015, the authors reported a total of 38 patients at 4 centers with ureteral strictures. Only patients that were determined and verified to have ureteral stricture occur after ureteroscopy were included in this study. Clinical variables such as stricture location, treatment modality used, and clinical outcomes were examined.

Their results of this review revealed that 73% of ureteral strictures occurred on the left side and of these, the majority were at the proximal (50%) or distal (42.5%) ureteral. About 30% of patients were successfully treated with endoscopic techniques alone. However, the majority of patients required complex reconstructive surgeries and even nephrectomy to treat their ureteral strictures. From these results the authors conclude that more emphasis ureteral stricture treatment strategies must be implemented.
