Doppler Ultrasonographic Evaluation of Erectile Dysfunction in a Northern Nigerian Tertiary Hospital

Colour duplex Doppler is a noninvasive tool for the evaluation of the vascular mechanism of erectile dysfunction (ED). It can be used to determine the integrity of the vascular mechanism and to differentiate between arterial and venous insufficiency.

To identify the vasculogenic causes of ED and subclassify them into arteriogenic, venogenic, or mixed to assist in predicting the clinical outcome.

A retrospective study was conducted at the Department of Radiology, ABUTH Zaria, from records of patients who had presented to the Doppler suite with symptoms of ED available between July 2020 and August 2022.

A total of 23 patients were involved in this study. The age range was 25-66 years. The majority of the patients were seen in age groups 51-60 years and 41-50 years with 48% (11) and 22% (5), respectively. Only 3 (13%) of the patients were found to have normal penile Doppler study, 12 (52%) patients were found to have arteriogenic, and another 4 (17.4%) patients were found to have venogenic cause. In four (17.4%) patients, there was mixed/inconclusive picture. Among the nine (39%) patients with Peyronie's disease, only one showed normal Doppler study. The incidence of vasculogenic cause of ED was found to increase with age.

The colour Doppler study is an important noninvasive nonionizing radiation tool for swift evaluation of penile erectile function and, thus, helps in classifying ED causes into structural, vascular, or possibly psychogenic, hence guiding the clinicians on the therapeutic options.
