Objective: To evaluate the performance of real time elastosonography (RTE) in the iden- tification of different types of penile lesions in patients with Peyronie’s disease. Materials and methods: Seventy four consecutive patients with complaints of Peyronie’s disease underwent B-Mode ultrasonography (US) and RTE of the penis in the same sit- ting. In each patient all sequences of elastosonography and B-Mode US were recorded and compared to evaluate the diagnostic performance of the new imaging technique. Results: B-Mode US detected penile plaques in 64 patients (86.41%) and elastosonography con- firmed these data. In the remaining 10 patients elastosonography documented, in five of them, areas of reducing elasticity suggesting the presence of initial fibrosis. Cohen’s K was used to eval- uate the discordances between B-Mode US and Elastosonography scan. A p value < 0.05 (two tailed) was considered statistically significant. The penile curvature (K = 0.353; p = 0.125) and the painful erection (K = 0.500; p = 0.248) evaluations were discordant: the B-mode US underestimat- ed the positive cases. Instead the penile plaque and curvature > 30°, and the penile plaque evalua- tions were completely concordant. Conclusions: RTE is a simple, non invasive, rapid complementary imaging technique that may improve the accuracy of B-Mode US in detecting penile lesions in patients with Peyronie’s disease.

Abstract
Objective: To evaluate the performance of real time elastosonography (RTE) in the iden- tification of different types of penile lesions in patients with Peyronie’s disease. Materials and methods: Seventy four consecutive patients with complaints of Peyronie’s disease underwent B-Mode ultrasonography (US) and RTE of the penis in the same sit- ting. In each patient all sequences of elastosonography and B-Mode US were recorded and compared to evaluate the diagnostic performance of the new imaging technique. Results: B-Mode US detected penile plaques in 64 patients (86.41%) and elastosonography con- firmed these data. In the remaining 10 patients elastosonography documented, in five of them, areas of reducing elasticity suggesting the presence of initial fibrosis. Cohen’s K was used to eval- uate the discordances between B-Mode US and Elastosonography scan. A p value < 0.05 (two tailed) was considered statistically significant. The penile curvature (K = 0.353; p = 0.125) and the painful erection (K = 0.500; p = 0.248) evaluations were discordant: the B-mode US underestimat- ed the positive cases. Instead the penile plaque and curvature > 30°, and the penile plaque evalua- tions were completely concordant. Conclusions: RTE is a simple, non invasive, rapid complementary imaging technique that may improve the accuracy of B-Mode US in detecting penile lesions in patients with Peyronie’s disease.File | Dimensione | Formato | |
