Outcome Measures

Primary Outcomes (4)

  • Reliability of BPH 3-item questionnaire

    Reliability was assessed by internal consistency and test-retest correlation. (ρ) correlation, with the IPSS (total score / voiding domain (ie Q.1, 3, 5, 6) and prostate volume measured by TRUS.

    up to 24 weeks

  • Internal consistency of BPH 3-item questionnaire

    Internal consistency was assessed by Cronbach's alpha coefficients, with \>0.7 being considered acceptable

    up to 24 weeks

  • Test-retest reliability of BPH 3-item questionnaire

    Test-retest reliability was assessed by intra-class correlation coefficient. Values between 0.6 and 0.8 indicate substantial agreement, and values over 0.8 indicate near-perfect agreement

    up to 24 weeks

  • The convergent validity of the BPH 3-item questionnaire

    was estimated by Spearman rho (ρ) correlation, with the IPSS (total score / voiding domain (ie Q.1, 3, 5, 6) and prostate volume measured by TRUS.

    up to 24 weeks

Study Arms (2)

Subject with male LUTS

Male subjects who have been bothered by male LUTS for at least 4 weeks and are still able to pass urine on their own without the need of assistance or urethral catheterization.

Other: BPH 3-item questionnaire

Subject who is waiting for their transurethral ablative prostate surgery

Male subjects who are waiting for BPH surgery and are still able to pass urine on their own without the need of assistance or urethral catheterization.

Other: BPH 3-item questionnaire

Interventions

BPH 3-item questionnaire. The questionnaire consists of only three items. A raw score ranging from 0 to 5 is assigned to each of the items, giving a final total score varying from 0 (no symptom) to 15 (very symptomatic).
