Discordant erectile function assessment between validated questionnaire scores and penile Doppler ultrasound in Peyronie's disease.

Peyronie's disease results in curvature of the penis which may cause difficulty with penetrative intercourse. The diagnosis of Peyronie's disease is easily obtained through history and physical examination alone, but the severity of erectile dysfunction relies on patient history and use of validated questionnaires. However, erectile dysfunction questionnaires were not validated in the Peyronie's disease population and may not be a reliable assessment. Penile Doppler ultrasound is a noninvasive tool that assesses vascular function. We hypothesized that penile Doppler ultrasound will be discordant with International Index of Erectile Function (IIEF) results in men with Peyronie's disease and erectile dysfunction. In this cross-sectional study, we reviewed a prospectively collected database of men with Peyronie's disease. In total, 108 men had questionnaire and ultrasound data. Of them, 87 had erectile dysfunction based on IIEF-EF or IIEF-5 (SHIM). However, 48 (55%) of those men had normal vascular parameters. Interestingly, among a subgroup of 33 men with severe erectile dysfunction on IIEF-EF or IIEF-5, 20 (61%) had normal vascular parameters. Our study demonstrates significant discordance between questionnaires and penile Doppler ultrasound. Therefore, ultrasound may be a useful tool in the workup of men with Peyronie's disease and erectile dysfunction.
