    Abstract:
    BACKGROUND: Benign prostatic hyperplasia (BPH), also referred to as enlarged prostate, is a highly prevalent condition in men aged 50 years or older. It is a progressive disease with significant morbidity from complications. OBJECTIVE: The purpose of this study was to assess the likelihood of having acute urinary retention (AUR) and prostate surgery after initiating therapy with an alpha blocker or 5-alpha reductase inhibitor in a real-world setting. STUDY DESIGN: This was a retrospective study of patients who were treated for BPH between January 1, 2003, and November 30, 2003, in a large, national managed care claims database. Outcomes measures of interest included rate of AUR, prostate surgery, and surgical complications. RESULTS: There were 2959 patient records with a diagnosis of BPH who were taking prostate medications in the database. Eighty-nine percent of patients were receiving alpha blocker therapy, whereas 11% of patients were receiving 5-alpha reductase inhibitors. Overall, the 1-year AUR rate was 12.1%, and the prostate surgery rate was 5.8%. Patients who initiated 5-alpha reductase inhibitor therapy only were less likely to have AUR or surgery compared with patients taking alpha blockers, although surgical differences did not reach statistical significance (P = .0576). Overall, the surgical complication rate was 49.4%, and the rate of AUR within 180 days of prostate surgery was 30.6%. Rates of prostate surgery, AUR, and surgical complications all increased with age. CONCLUSION: Patients receiving 5-alpha reductase inhibitor therapy alone were less likely to have AUR compared with patients receiving alpha blockers and tended to be less likely to have surgery (P = .054).
