title: Assessing treatment results in benign prostatic hyperplasia.
abstract: This article discusses general and specific principles for the evaluation of BPH. General principles include bias elimination; sample size; appropriate and sensitive parameters of evaluation; blind, double-blind, controlled, and placebo-controlled studies; and statistical versus clinical significance. Specific considerations include prostate volume and size; flowmetry; residual urine volume; cystometry and pressure flow studies; and symptomatic versus urodynamic improvement.
