Abstract:
Objective To investigate the risk factors of ureteral stricture after ureteroscopic lithotripsy in patients with ureteral calculi.
Methods The risk factors of ureteral stricture after ureteroscopic lithotripsy based on the clinical data of 708 patients from January 2014 to December 2015 in our hospital were analyzed retrospectively.
Results A total of 36 patients (5.1%) with ureteral stricture were found. The risk factors for the ureteral stricture were: impacted calculi (OR=3.61, 95%CI=2.12~6.08, P<0.001), multiple calculi(OR=3.22, 95%CI=1.01~5.77, P<0.001), big stone(OR=2.41, 95%CI=1.14~4.18, P<0.001), holmium laser lithotripsy (OR=1.36, 95%CI=1.02~3.93, P=0.031), long course of disease (OR=1.12,95%CI=1.02~3.42, P=0.038).
Conclusion For patients with impacted calculi, multiple stones, large stones and patients who were treated with holmium laser lithotripsy, we should be careful not to injury the ureter, and actively prevent and control the occurrence of ureteral stenosis
