超声检查在阴茎折断诊断中的应用

The application of color Doppler ultrasound in fracture of penis

目的分析阴茎折断的声像图特征,探讨超声对其诊断价值。方法分析12例阴茎折断的二维声像图和血流信号特点,其中3例陈旧性阴茎折断患者经阴茎根部注入酚妥拉明,观察阴茎海绵体动脉血流频谱的特征。结果所有患者患侧阴茎海绵体白膜连续性中断。急性阴茎折断患者的中断部位为不均质低回声或混合回声,该处白膜外可见混合团状回声,内无血流信号;阴茎浅筋膜层软组织肿胀;陈旧性阴茎折断患者中断部位呈强回声伴回声衰减,内无血流信号,注药后见阴茎向患侧弯曲。结论超声能显示中断部位、血肿大小及血流情况等,可为临床治疗提供依据。

Objective To retrospectively analyze the sonographic characteristics of fracture of penis and to evaluate the diagnostic value of ultrasound in this disease. Methods Sonographie imagos of 12 eases with fracture of penis were reviewed. Phentolamine was injected via the root of penis in three cases with obsolete fracture, then the spectral characteristics of arterial blood flow of corpus cavemosum penis were observed. Results Abscise of the corpus cavemosum penis albuginea was detected in all cases. For the acute cases, there was nonhomogeneous low level echo or mixed echo in the broken position, outside the albuginea there was mixed echo clumping with no flow signal inside and anadosma soft tissue swelling. In the obsolete cases, there was high- level echo in the broken position, accompanied with echo attenuation, no flow signal inside. After injection, the penis bent to the broken side. Conclusion Ultrasound can display the position and range of the fracture, size of the haematoma and blood flow. It is an effective method in the diagnosis of fracture of penis.
