Detailed Description
A new BPH 3-item questionnaire has recently been developed and published, and it may serve as a screening tool for male-LUTS due to symptomatic BPE. 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). This questionnaire has been translated and validated into five different European languages and was harmonized cross-culturally for linguistic validation, followed by psychometric accuracy testing.
This new questionnaire may help rationalize more early commencement of therapy aimed at reducing the prostate size for the treatment of male LUTS due to BPE.

Outcome Measures
Primary Outcome Measures
- Reliability of BPH 3-item questionnaire [up to 24 weeks]
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.
- Internal consistency of BPH 3-item questionnaire [up to 24 weeks]
Internal consistency was assessed by Cronbach's alpha coefficients, with >0.7 being considered acceptable
- Test-retest reliability of BPH 3-item questionnaire [up to 24 weeks]
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
- The convergent validity of the BPH 3-item questionnaire [up to 24 weeks]
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.
