Brief Summary

Benign prostatic hyperplasia (BPH) is a common condition among older men. The efficacy of α1-blockers for treating BPH has been well documented and they are recommended for the treatment of BPH by clinical guidelines. It is not well known if a stratification based on the grade of BOO and bladder contractility has any predictive value for patients who are treated with an α1-selective blocking agent. In our study, we investigated possible differences in treatment outcome between patients with and without BOO, and with or without proper contractility who are treated with alfuzosin. So we will compare the quantified improvements 12 months after alfuzosin medication in LUTS/BPH patients by the grade of BOO and/or bladder contractility.

Outcome Measures

Primary Outcomes (2)

  • Primary Outcome; International Prostate Symptom Score Changes Between 4 Groups Compared to Baseline After 12 mo Treatment

    international prostate symptom score was measured at baseline and 12 months. total scores on a scale range (from 0 to 35) higher values represent a worse outcome Baseline score minus 12-month score

    12months

  • Treatment Efficacy Was Analyzed by Validated Symptom Scores.

    Alfuzosin was administered daily (10 mg). After 12 months of treatment, efficacy and safety were analyzed. Efficacy was measured by validated symptom scores (using IPSS ). IPSS score change was measured pre- and post- treatment.

    12 month

Secondary Outcomes (3)

  • Changes of International Continence Society (ICS)-Male Questionnaire (Voiding Sum)

    12months

  • Changes of Peak Flow Rates on Uroflowmetry

    12 months

  • Changes in Residual Urine Volumes

    12 months
