A Critical Analysis of Methodology Pitfalls in Duplex Doppler Ultrasound in the Evaluation of Patients With Erectile Dysfunction: Technical and Interpretation Deficiencies.

ABSTRACT:

Background

Penile duplex Doppler ultrasound (PDDU) is a minimally invasive tool to evaluate erectile hemodynamics in patients with erectile dysfunction (ED). Despite decades of use, there is still a large variability in PDDU protocols, and a high rate of false diagnosis is reported.

Aim

Review of PDDU methodology in the published literature addressing protocol heterogeneity, technical and interpretation challenges.

Methods

A PubMed literature search was performed using the search terms "penile doppler ultrasound", "penile duplex ultrasound" or "penile ultrasound", and "Erectile dysfunction". Studies were analyzed for the presence of the following elements in reporting of the PDDU protocol: (i) intracavernosal vasoactive agents used, (ii) use of a redosing protocol, (i
