Efficacy of pre-operative silodosin on flexible ureteroscopy procedure: A randomized controlled study

Abstract

ABSTRACT Objectives To evaluate the impact of silodosin on stages of flexible ureteroscopy (F-URS) procedures, complications, and stone-free rate (SFR). Patients and Methods A prospective, randomized, controlled comparison research was conducted on 106 patients who were randomly allocated into two groups: the study group (52 patients) received F-URS with preoperative daily uptake of 8 mg silodosin for 10 days, and the control group (54 patients) received F- URS without silodosin uptake. Two patients were lost during the follow up in the study group and four patients were also lost in the controls. Results Operative time, application access sheath time (AAST), entrance to ureteric orifice time (ETUOT), and entrance to bladder time (ETBT) were significantly lower in the study group compared to controls. Meanwhile, F-URS time & laser time was higher in the study group compared to controls but without statistically significant difference. Complications were insignificalty different between both studied goups with no impact on SFR. Conclusion Before ureteroscopy, silodosin, an adjunctive alpha-blocker therapy, was successful in treating stones resulting in shortening the procedural time, with no impact on SFR or complication rate.
