The responsiveness of the ICSmale questionnaire to outcome: evidence from the ICS-'BPH' study.

Objective: To evaluate the responsiveness of the ICSmale questionnaire to the outcome of treatments for lower urinary tract symptoms (LUTS).

Patients And Methods: Consecutive men aged >45 years attending 23 urology centres in 12 countries, with symptoms suggestive of bladder outlet obstruction secondary to benign prostatic hyperplasia (BPH), were recruited to Phase I of the International Continence Society (ICS)-'BPH' study. In Phase II of the ICS-'BPH' study, 355 men in 15 centres in nine countries were followed up, having proceeded to treatment according to clinical practice. All men completed the ICS-'BPH' study questionnaire at baseline and follow-up, including the ICSmale which concerns LUTS and related problems.

Results: Patients included in Phase II were similar to those in Phase I according to age and levels of baseline symptoms. Patients received a range of treatments: 32% TURP, 29% drug therapies, 20% watchful waiting, 9% minimally invasive therapies and 10% 'others' (including open prostatectomy). For patients who underwent TURP, most LUTS, including voiding and filling symptoms, were highly statistically significantly better at follow-up than at baseline (P<0.0001). For drug, minimally invasive and 'other' treatments, fewer LUTS were highly statistically significantly better. For those undergoing watchful waiting, no symptoms were significantly different between baseline and follow-up.

Conclusion: The ICSmale questionnaire, in addition to being psychometrically valid and reliable, is responsive to change in outcome.
