Background : Erectile dysfunction is a condition in men that often has a negative impact on quality of life. Penile grayscale ultrasonography in the flaccid phase is a non-invasive imaging modality to evaluate anatomy of the right and left corpora cavernosa, cavernosa artery, and corpora spongiosa of the penis. Objective : To determine the profile of penile structure in patients with erectile dysfunction evaluated using a gray scale ultrasonography in the flaccid phase. Methods: This was a retrospective descriptive study in male patients (aged 30-65 years) with erectile dysfunction who underwent an ultrasonography examination at the Radiology Department of Dr. Soetomo Hospital, Surabaya in December 2019 to June 2020. The degree of erectile dysfunction is based on the value of International Index of Erectile Function-5 (IIEF-5). Penile ultrasonography was performed during the flaccid phase, cavernous artery diameter was measured, diameter of the right and left corpora cavernosa and corpora spongiosa were measured at the base of the penis. Results: 30 patients with erectile dysfunction, 11 (36%) mild patients, 8 (27%) mild-moderate patients, 8 (27%) moderate grade patients, and 3 (10%) severe patients. Mean diameter of cavernous artery, corpora cavernosa, corpora spongiosa of erectile dysfunction patients measured in the flaccid phase was 0.062 cm, 1.0 cm, and 0.9 cm, respectively. Conclusion: Penile grayscale ultrasonography in the flaccid phase can be used to measure the diameter, where the more severe degree of erectile dysfunction, diameter of corpora cavernosa, corpora spongiosa, and cavernosa artery became smaller.
