[QUOTE="madman, post: 199228, member: 13851"] [B]Background: [/B]The method used in the first assessment of patients with veno-occlusive erectile dysfunction (ED) is penile color Doppler ultrasonography (PCDU). However, cavernosography performed following intracavernosal pharmacostimulation is accepted as a more precise method for showing venous leakage. [B]Aims:[/B] The objectives of this study were to compare results obtained from patients undergoing PCDU, and those undergoing cavernosography, and to investigate the diagnostic value of PCDU in the diagnosis. [B]Methods:[/B] A total of 133 patients who presented at the urology clinic due to ED have veno-occlusive dysfunction (VOD) detected as a result of PCDU and underwent cavernosography for further assessment when scheduled for penile embolization.
