Abstract
High-resolution ultrasonography was performed on 58 patients with Peyronie’s disease and on 6 healthy men; in 3 patients the examination was repeated during medical treatment for a follow-up period of 4 months. Peyronie’s plaques always corresponded to abnormal echographic findings. In 54/58 cases (93%) they appeared as hyperechoic lesions. In 4 cases (7%) the plaques were hypoechoic and corresponded to a localized widening of the pericavernous tissues: this condition was observed more frequently in the earliest stages of the disease. There was good agreement between the palpable size of the plaques and their size measured by ultrasonography, with some degree of clinical overestimation of the smallest lesions. Calcified mature plaques corresponded to dense hyperechoic lesions with acoustical shadowing. High-resolution ultrasonography is proposed as a first-line diagnostic approach and as a reliable follow-up examination for Peyronie’s disease. The possibility of differentiating calcified plaques from the more recent ones is helpful to allow a correct choice of medical or surgical treatment.
