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

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.
