title: Application of ultrasonography and the resistive index for evaluating bladder outlet obstruction in patients with benign prostatic hyperplasia.
abstract: Benign prostatic hyperplasia (BPH) is an extremely common and chronic condition that can lead to bladder outlet obstruction (BOO) in elderly men. Although pressure-flow studies are considered the most reliable method for evaluating BOO, they are invasive and complicated. Transrectal ultrasonography (TRUS) is a promising alternative because of its minimal invasiveness. Recently, TRUS imaging has been shown capable of measuring the resistive index, a useful parameter for evaluating BOO and for determining proper medical intervention in patients suffering from BPH.
