Impact of drug therapy on benign prostatic hyperplasia-specific quality of life.

Quality of life (QOL) is an important issue when assessing medical treatment of benign prostatic hyperplasia (BPH). There are many QOL questionnaires available, and disease-specific questionnaires are being developed. Currently, most patients undergoing treatment for BPH receive alpha-blockers or finasteride. To determine which QOL measures are being used, we did a Medline search covering the past 10 years and found 11 studies in which BPH-QOL was investigated. The wide variety of questionnaires used made comparison between drug studies difficult. When comparing studies that used at least one similar questionnaire to that of another drug study, we found alpha-blocker treatment excelled over finasteride in improving BPH-QOL in the areas of earlier response, larger decreases in mean changes, and reduced sexual side effects. QOL assessment should be a routine part of BPH treatment, and more standardized and validated measures should be used to allow for comparative, meaningful analyses.
