Abstract:

Background:Urolithiasis is a globally prevalent disease with an increasing worldwide prevalence of 4 to 5%. A ureteral stricture is a common and serious complication of ureteroscopic lithotripsy (URSL) and was reported in the literature in the range of 0.2 to 24%. The incidence of laser lithotripsy has increased substantially in the past few years with their own advantages and complications.
Methods:This retrospective observational (case-control) study was conducted from January 2021 to December 2022, including patients undergoing URSL for ureteral stone disease. Post-operative follow up was done for 12 months using ultrasound. Patients developing hydronephrosis on ultrasound and/or pain during the follow up period were subjected to Computed Tomography Urography to confirm the diagnosis. Multiple logistic regression analysis was done to measure the risk factors, Odd’s ratio was calculated, and p-value of <0.05 was considered statistically significant.
Results: The mean stone burden was 10.2 mm with mean hardness of 970 HU. 189 patients had impacted stones with various degrees of impaction; smooth stone surface was present in 134 patients. The mean duration of lithotripsy was 30 minutes. The overall post operative complication rate was 17% with stricture formation in 5.9% of patients.
Conclusions:Stone burden, stone surface characteristic, energy source used (Holmium Laser vs Pneumatic), and impacted nature of calculi with degree of impaction were found to be associated with development of ureteric strictures post URSL
Keywords: hydronephrosis, laser, stricture, ureteral stone disease, ureteroscopic lithotripsy.
