Aims: The aim of this study was to evaluate the effects of alpha blockers in women with lower urinary tract symptoms. Methods: We conducted systematic review and meta-analysis on published a priori protocols. We searched multiple data sources for published and unpublished randomized controlled trials in any language. Primary outcomes included urologic symptom scores, quality of life, and overall adverse events. We performed meta-analysis using RevMan 5.3 and rated the certainty of evidence using Grading of Recommendations, Assessment, Development, and Evaluation. Results: Alpha blockers likely reduced urological symptom score (mean difference: −1.50, 95% confidence interval: −2.91 to −0.09; moderate certainty of evidence). Alpha blockers may improve quality of life (standardized mean difference: −0.35, 95% confidence interval: −0.85 to 0.15; low certainty of evidence) and have little to no difference in overall adverse events (risk ratio: 1.09, 95% confidence interval: 0.55 to 2.15; low certainty of evidence). Based on five studies comparing combination therapy with alpha blockers and anticholinergics to anticholinergic monotherapy, combination therapy likely results in little to no difference in urological symptom score (mean difference: −0.35, 95% confidence interval: −1.98 to 1.27; moderate certainty of evidence) and quality of life (mean difference: −0.11, 95% confidence interval: −0.48 to 0.27; moderate certainty of evidence). We are very uncertain about the effect of combination therapy on overall adverse events (risk ratio: 1.07, 95% confidence interval: 0.40 to 2.84; very low certainty of evidence). Conclusion: Alpha blocker monotherapy for the women with lower urinary tract symptoms regardless of the underlying cause likely has satisfactory efficacy compared with placebo. However, combination therapy with anticholinergics likely has no additional effect on urologic symptom score and quality of life compared with anticholinergic monotherapy.
