Penile ultrasound is frequently used in the diagnostic evaluation of a patient with erectile dysfunction (ED). However, it also plays an important role in penile assessment by providing an anatomic and functional vascular assessment in a multitude of other conditions, including Peyronie’s disease, high-flow priapism, penile fracture, penile urethral strictures, urethral stones, urethral diverticula, or masses involving deep tissues of the penis. This imaging modality, which incorporates real-time imaging of the vasculature, vessel wall compliance, and blood flow dynamics in an end-organ small-vessel arterial system, also plays a central role in the early detection and diagnosis of small-vessel disease. Penile ultrasound, thus, provides a readily available, minimally invasive diagnostic modality that evaluates both the structural anatomy and functional hemodynamics at a reasonable cost.
