Objectives: To establish a relationship between Doppler-Duplex colour ultrasound after prostaglandin intracorporeal injection and psychological features in patients suffering from erectile dysfunction. Methods: Forty two patients with erectile dysfunction were prospectively evaluated with Doppler-Duplex colour ultrasonography after intracavernosal injection of 20 micrograms of E1 prostaglandin. Dynamic vascular pattern were analyzed and penile tumescence were graded in poor, moderate or good (I, II, III). All of them completed the International Index of Erectile Dysfunction, International Exam of Personality Traits (IPDE) and the Symptom Checklist (SCL-90). Results: 29 patients (69.05%) showed a normal ultrasonography response (Peak Systolic Velocity >30 cm/s; Telediastolic velocity negative or less than 5cm/s and penile tumescence grade III) and were classified as good responders with probably psychogenic erectile dysfunction. Patients who did not show these values were classified in the group of erectile dysfunction of vascular origin. We found significative differences between the two groups in sex desire, tumescence and paranoid personality. The more frequent personality features were paranoid and squizoid (excentric) and ananchastic and anxious (fearful ones). Somatization and obsessive-compulsive symptoms have been outlined over the rest. We have found that paranoid personality is sixteen times more frequent in patients with normal ultrasonography. Conclusions: Psychological features and dysfunctional personality traits accompany psychogenic and organic erectile dysfunction, thus it is thought that mixed aetiology coexist in this patients. Doppler-Dupplex Colour ultrasound is an useful method to exclude organic vascular factors. On de basis of our article, is more common to find psychological discomfort and dysfunctional personality traits in patients with normal ultrasound, which may help in their diagnosis and treatment.
