This retrospective study aims to assess the impact of early vs delayed 5-alpha-reductase inhibitor (5ARI) therapy in patients with BPH on alpha-blocker (AB) therapy and the risk of acute urinary retention (AUR), prostate-related surgery, and emergency surgery (defined as prostate surgery occurring within 30 days of AUR). The MarketScan database will be utilized for this study (2000-2008).
