Abstract
280 patients (aged 28 to 74 years, mean 57) with erectile failure (EF) underwent colour Doppler and duplex ultrasound imaging (CDI) following intracorporeal papaverine. After achieving a full, or nearly full, erection visual inspection and palpation revealed plaques and/or constriction or deformity of the penis in 55 (20%) cases. 10 (4%) were known to have Peyronie's plaques prior to referral. Of these 55 patients ultrasound showed focal echogenic plaques in 14 (25%) and diffuse thickening of the tunica albuginea in 41 (75%). CDI diagnosed arteriogenic EF in 20 (36%) of these patients, venous leak in 10 (18%), arterial and venous in two (4%) and a normal response in 23 (42%). In 11 (20%) patients (seven with arteriogenic EF and four with venous leak) the plaque was seen to be affecting vessels. These results indicate that abnormalities of the tunica albuginea are far more common in patients presenting with erectile failure than previously thought. We believe that the diffuse thickening is a form of Peyronie's which is only recognized after pharmacological induction of penile erection.
