To evaluate the performance of real time elastosonography (RTE) in the identification of different types of penile lesions in patients with Peyronie's disease.
Seventy four consecutive patients with complaints of Peyronie's disease underwent B-Mode ultrasonography (US) and RTE of the penis in the same sitting. 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.
B-Mode US detected penile plaques in 64 patients (86.41%) and elastosonography confirmed these data. In the remaining 10 patients elastosonography documented, in five of them, areas of reducing elasticity suggesting the presence of initialfibrosis. Cohen's K was used to evaluate 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 underestimated the positive cases. Instead the penile plaque and curvature > 30 degrees, and the penile plaque evaluations were completely concordant.
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.
评估实时弹性超声成像（RTE）在诊断佩罗尼氏病患者不同类型阴茎病变中的性能。
74例因佩罗尼氏病前来就诊的患者在同一次检查中接受了阴茎的B超（US）和RTE检查。记录每位患者弹性超声成像和B超的所有序列，并进行比较，以评估这种新成像技术的诊断性能。
B超在64例患者（86.41%）中检测到阴茎硬结，弹性超声成像证实了这些数据。在其余10例患者中，弹性超声成像记录显示，其中5例存在弹性降低区域，提示存在早期纤维化。采用科恩Kappa系数评估B超与弹性超声成像扫描结果之间的不一致性。p值<0.05（双侧）被认为具有统计学意义。阴茎弯曲度（K = 0.353；p = 0.125）和疼痛性勃起（K = 0.500；p = 0.248）的评估结果不一致：B超低估了阳性病例。相反，阴茎硬结和弯曲度>30度以及阴茎硬结的评估结果完全一致。
RTE是一种简单、无创、快速的辅助成像技术，可提高B超在检测佩罗尼氏病患者阴茎病变中的准确性。
