  • Primary Outcome; International Prostate Symptom Score Changes Between 4 Groups Compared to Baseline After 12 mo Treatment [ Time Frame: 12months ]

    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

  • Treatment Efficacy Was Analyzed by Validated Symptom Scores. [ Time Frame: 12 month ]
    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.
Primary outcome; IPSS changes between 4 groups compared to baseline after 12 mo treatment [ Time Frame: 12months ]

The Long Term Effects of Alfuzosin(Xatral XL) in Lower Urinary Tract Symptoms(LUTS)/BPH Patients
The Long Term Effects of Alfuzosin(Xatral XL) in LUTS/BPH Patients: Evaluation of Voiding and Storage Function According to Bladder Outlet Obstruction Grade and Bladder Contractility

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.

  1. Primary objective To evaluate efficacy on voiding and storage symptoms in LUTS/BPH patients after 12 months of treatment with Xatral XL® by the grade of bladder outlet obstruction and/or bladder contractility
  2. Secondary objectives To evaluate efficacy on voiding and storage symptoms in LUTS/BPH patients after 3 months and 6 months of treatment with Xatral XL® by the grade of bladder outlet obstruction and/or bladder contractility To evaluate efficacy on maximal flow rate (MFR) and post-voided residual urine (PVR) To evaluate on voiding frequency, urgency severity & frequency, and nocturia To evaluate patient tolerability to the medication To evaluate global impression of improvement (GII)
