VJPU - 6.A. Diagnostic Workup

This video covers how to perform a penile duplex Doppler ultrasound (PDDU). A PDDU is performed as part of the normal work-up for erectile dysfunction (ED). It helps determine if a patient’s ED is due to arterial insufficiency, venous leakage, or a combination of the two. Additionally, PDDU can be used to assess Peyronie’s disease and provides in-depth information on plaque size and location, as well as the structural abnormalities in the corpora.

In this video, we demonstrate a step-by-step protocol and highlight take-home tips and tricks for PDU. This video serves as a resource for clinicians who are seeking to familiarize themselves with the methodology of performing a PDDU.

Thread 'Penile Doppler Explained: Normal Study vs Arterial Insufficiency and Venous Leak'

Aug 23, 2025

Penile Doppler ultrasound is a vital tool for evaluating vascular causes of erectile dysfunction. In a normal study, adequate arterial inflow is demonstrated by a peak systolic velocity (PSV) greater than 30–35 cm/s, and proper venous occlusion is confirmed by a low end diastolic velocity (EDV) approaching zero. This pattern supports the achievement and maintenance of a firm erection. In contrast, the abnormal case shows a PSV less than 25 cm/s, indicating arterial insufficiency, and a persistently elevated EDV of 5–9 cm/s with continuous diastolic flow...
