Color Doppler Sonographic Evaluation of Men with Peyronie's Disease

Color Doppler sonographic evaluations of penile vascularity of 50 impotent patients, 24 of them were known to have the Peyronie's disease, were done. Eight (33.2%) of the patients with Peyronie's disease had abnormal blood flow parameters consistent with the arterial insufficiency. One patient (3.8%) had normal results but prolonged erection. The remaining 15 (62.5%) had venous leakage. Whereas, 14 (53%) of the 26 impotent patients without Peyronie's disease had arterial pathology, 7 (26.9%) with venous insufficiency and 5 (19.6%) with psychogenic or neurogenic impotence. Our results indicate that veno-occlusive dysfunction is the principal cause of impotence.
