ABSTRACT Treatment with _α_1-adrenergic receptor blockers improves lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia. This study was conducted to test the


hypothesis that induction of apoptosis in prostate tissue could be a mechanism underlying the observed clinical benefit. This placebo-controlled, double-blind, randomized trial enrolled 536


men with LUTS who were treated with alfuzosin (10 or 15 mg) once daily or placebo for 3 months. Total prostate and transition zone volume was measured by standardized transrectal ultrasound


measurements at baseline and 3 months. Total prostate volume increased by 0.4 ml from baseline in placebo patients but decreased by −0.25 ml in the combined alfuzosin groups. Percentage


change was not statistically significantly different between the placebo and alfuzosin groups. Changes in transition zone volumes from baseline were similar in both treatment arms;


percentage change was not statistically significantly different between the placebo and alfuzosin groups. Volume changes did not correlate with prostate volumes at baseline. Overall, neither


total prostate nor transition zone volume increased or decreased systematically within the 3-month treatment period. If alfuzosin-induced apoptosis in prostate tissue, it was not evident by


a measurable change in prostate volume after 3 months’ treatment. Further analysis at 1 and 2 years will determine the effect of longer-term treatment. Access through your institution Buy
