Relationship between Penile Fracture and Peyronie's Disease: A Prospective Study

Abstract

Peyronie's disease is postulated to be initiated by repetitive minor traumas to the fully or partially erect penis. We investigated Peyronie's disease prospectively in cases treated for penile fracture (PF) within the last 20 years. Medical records of 63 cases treated for PFs were reviewed. Subjects were required to self-assess their current penile morphologies and sexual functions. Penile nodules and Peyronie's plaques were also evaluated with physical examination, ultrasonography and magnetic resonance imaging (MRI), and penile curvatures with auto-photography, and sexual function with international erectile function index (IIEF). Of the 63 cases (mean age 37 years), 46 who had mean follow-up of 63 months were re-evaluated. The mean IIEF-5 score was 23.23.1. Painful erections (n5), penile nodules (n5) and also penile curvatures 20° (n2) were investigated. No Peyronie's plaque was palpated in any of the cases. Ultrasound and MRI showed fibrotic nodules of 5 mm in diameter, which extended into the subtunical area in the rupture site in 54% of the cases, although any thickening and Peyronie's plaque were not found in the tunica albuginea and intracavernosal septum of the cases examined. In PF patients treated surgically, the erectile function and penile morphology were preserved. In our cases PFs did not induce the development of Peyronie's disease. © 2011 Macmillan Publishers Limited All rights reserved.
