[Intravesical prostatic protrusion in diagnosing infravesical obstruction in men with benign prostatic hyperplasia].

Infravesical obstruction (IVO) is an important characteristic of the functional state of male lower urinary tract. It is believed that IVO confirmed by pressure-flow study findings warrants switching from a medical to surgical management of lower urinary tract symptoms (LUTS). Intravesical prostatic protrusion (IPP) is a new indicator for detecting IVO secondary to benign prostatic hyperplasia (BPH). This indicator has several advantages over other non-invasive methods for evaluating IVO. The initial findings on the relationship between IPP and IVO suggest the feasibility of its clinical use as a screening tool in men with obstructive voiding symptoms.
