The use of baseline clinical measures to predict those at risk for progression of benign prostatic hyperplasia.

Although histologic changes of benign prostatic hyperplasia (BPH) begin in men when they are in their thirties, symptomatic BPH characterized by lower urinary tract symptoms (LUTS) typically do not develop for several decades. Progression of BPH may lead to significant voiding symptoms, acute urinary retention, and the need for prostate surgery. However, developing LUTS is not inevitable for men with histologic evidence of BPH. The ability to predict those men who are at risk for BPH progression is increasingly important because of recent evidence provided by the Medical Therapy of Prostate Symptoms study. This landmark study demonstrated that 5alpha-reductase inhibitors, alone or in combination with selective alpha-blockers, can delay or prevent the progression of BPH. In addition, the most important and consistent predictive factors for BPH progression are baseline prostate-specific antigen and prostate volume. Integration of these clinical parameters into clinical practice is influencing the decision regarding which men should observe or initiate treatment. This article highlights recent studies regarding the use of baseline clinical parameters on predicting BPH progression.
