Penile vascular assessment using color duplex sonography in men with Peyronie's disease.

Abstract

Duplex ultrasound provides a dynamic noninvasive functional assessment of penile vasculature in Peyronie's disease. Although corporeal veno-occlusive dysfunction has been considered the primary vascular etiology of erectile dysfunction associated with Peyronie's disease, arterial insufficiency is a major contributor, which is best detected before definitive therapy.
