Abstract/OtherAbstract:
This study aimed to investigate the predictive accuracy of carotid and cavernosal Doppler ultrasound findings for discriminating patients with vasculogenic erectile dysfunction (ED). Fifty patients with complaints of ED were included. B-mode ultrasound of bilateral carotid arteries were performed and peak systolic velocity (PSV), end-diastolic velocity (EDV) and intima-media thickness (IMT) values were measured. Afterwards, corresponding values of cavernosal arteries were obtained by penile color duplex ultrasonography (P-CDU). Of total 50 patients, 29 (58%) were included in vasculogenic ED group and 21 (42%) in non-vasculogenic ED group according to P-CDU findings. There was a significant difference between groups for cavernosal IMT (P=0.012) but not for carotid IMT (P=0.601). When patients were reclassified according to carotid IMT values (IMT of the first group <0.9 mm and the second 0.9 mm), carotid PSV and EDV values were different (P=0.033 and 0.018, respectively). Cavernosal PSV and EDV displayed no difference (P=0.816 and 0.123) while cavernosal IMT and percent change of cavernosal caliper were significantly different (P=0.014 and 0.018). Carotid PSV and EDV successfully mirrored respective measurements in cavernosal artery. However, carotid IMT failed to demonstrate such a correlation. Cavernosal IMT seems promising as an additional tool in the evaluation of cavernosal function.International Journal of Impotence Research advance online publication, 22 September 2011; doi:10.1038/ijir.2011.46.
