Response to Daily 10 Mg Alfuzosin Predicts Acute Urinary Retention and Benign Prostatic Hyperplasia Related Surgery in Men With Lower Urinary Tract Symptoms

Purpose: We analyzed the influence of treatment response on the risk of acute urinary retention and benign prostatic hyperplasia related surgery in 5,792 men complaining of lower urinary tract symptoms who were treated for 6 months with the selective α1-blocker alfuzosin at 10 mg once daily.Materials and Methods: The influence of dynamic variables (International Prostate Symptom Score change and bother during treatment) and baseline variables (patient age, prior acute urinary retention managed conservatively, prostate specific antigen, International Prostate Symptom Score and bother severity) on the risk of acute urinary retention and benign prostatic hyperplasia related surgery was estimated using the Kaplan-Meier method and log rank test. The associated HR and 95% CI were calculated using Cox proportional hazard models.Results: During alfuzosin treatment International Prostate Symptom Score improved by 3 or greater and greater than 6 points in 74.8% and 50.3% of men, respectively. In this unselected pop...
