Early echographical assessment of minimal lesions of cavernosum corpora and tunica albuginea in subjects with erectile dysfunction, suggestive of La Peyronie's disease

The aim of the study is to evaluate the incidence and the echographic characteristics of minimal lesions of cavernosum corpora and tunica albuginea (TA) in subjects reporting erectile dysfunction (ED), which could suggest the suspicious of La Peyronie's disease (LPD). In total, 185 patients (pts) underwent dynamic penile Ultrasound Color Doppler (USCD) for ED. None of the pts presented any clinical symptoms or any clinical findings for LPD. In this study we evaluated, using USCD, thickness, echogenicity, regularity of the surface profile of the dorsal TA, the intercavernous and the intercaverno-spongeous septa, and the extension of the eventual pathologic lesions. In all, 16 pts (8.7%) presented minimal lesions at the ultrasound examinations. In nine of these pts (56%) the lesion was localized at the dorsal position, in six (38%) on the intercavernous septum and in one patient (6%) in both positions. The dorsal lesions were represented in nodular form in four pts (4%), and in diffuse form in five pts (55%). The nodular form was present in all the intercavernous septal lesions observed. As reported in the literature, USCD represents the investigative technique of choice in the study of LPD and in ED. Furthermore, the results of this study suggest that this technique could allow the localization of minimal lesions attributable to LPD during a preclinical phase of this disease. The localization of these lesions could permit to start a therapeutic approach during an early phase of the disease.
