The efficacy of adjunctive alpha-blockers on ureteroscopy procedure for ureteral stones: a systematic review and meta-analysis
Abstract
Background: Urolithiasis cases are a common condition, and the number is still growing today. The prevalence of urinary tract stones globally currently ranges from 2-20% with a recurrence rate of around 50%. The present study aims to investigate the efficacy of adjunctive alpha-blockers in improving the success rate of ureteroscopy (URS) procedure for urolithiasis. Methods: We reviewed articles obtained from MEDLINE, CENTRAL, CINAHL, and Elsevier from 14 August to 9 September 2020, comparing alpha-blockers as adjunctive therapy, versus either a placebo or no drug at all, in post-URS urolithiasis patients. There were no restrictions on the type of URS and alpha-blockers given to patients. The quality of studies included was assessed using Cochrane’s Risk of Bias Assessment for Randomized-Controlled Trials. Results: Forest plot analysis emphasizes the statistically significant difference among the group, where the adjunctive alpha-blocker group had pooled relative risk (RR) of being stone-free, readmitted due to initial URS failure, having an overall complication, having haematuria, getting their ureteral mucous injured, and suffering a colic episode was 1.71 (95% CI, 1.11–1.24), 0.50 (95% CI, 0.25–1.01), 0.41 (95% CI, 0.27–0.61), 0.42 (95% CI, 0.22–0.79), 0.31 (95% CI, 0.13–0.73), and 0.21 (95% CI, 0.06–0.69), respectively. Conclusions: Alpha blockers minimize the frequency and duration of ureteral contractions, allowing smooth stone expulsion. With this knowledge, it is…
