Abstract

Purpose: In patients with erectile dysfunction, it is important to differentiate psychogenic from organic causes. Penile Doppler ultrasonography is a relatively inexpensive and minimally invasive tool for this purpose. This study was conducted to evaluate the causes of erectile dysfunction in an adult male population, using penile Doppler ultrasonography.

Materials and methods: A retrospective study was conducted in a single center. All patients who presented with complaints of erectile dysfunction and underwent penile Doppler ultrasonography between July 2014 and June 2016 were included in this study. All examinations were performed using GE Voluson S6 and GE Logiq P5 devices. Following baseline scans, an intracavernosal injection of 20 μg of prostaglandin E1 was given. Peak systolic and end diastolic velocities were measured in each cavernosal artery. Patients with a peak systolic velocity of <25 cm/s were considered to have arterial insufficiency, while an end diastolic velocity of >5 cm/s was considered to indicate venous incompetence.

Results: Out of 97 patients (mean age, 37.09±11.59 years; range, 19~69 years), 50 patients (51.5%) had normal findings, 24 patients (24.7%) had arterial insufficiency, 15 patients (15.5%) had a venous leak, and 8 patients (8.2%) patients had arterial insufficiency with a venous leak. Psychogenic erectile dysfunction was significantly higher among patients aged ≤40 years, while arterial insufficiency with or without a venous leak was significantly higher among patients aged >40 years (p=0.022).

Conclusions: A majority of the studied individuals demonstrated no organic cause of erectile dysfunction, thus confirming a high prevalence of the psychogenic etiology, particularly in relatively young individuals.
