| 目的 探讨彩色多普勒超声在阴茎异常勃起诊断中的价值。方法 回顾性分析经超声检查的16例阴茎异常勃起患者声像图表现。结果 阴茎异常勃起分缺血性和非缺血性2种, 非缺血性阴茎异常勃起多由外伤所致,患者阴茎海绵体内可见血肿或假性动脉瘤及海绵体动脉-海绵体窦状隙漏,一侧海绵体动脉血流速度明显增快,峰值流速(PSV)>40 cm/s,阴茎背深静脉增宽,血流速增快,流速(V)>20 cm/s;缺血性阴茎异常勃起患者阴茎海绵体回声随时间延长,内回声逐渐不均匀,海绵体动脉血流速减低,PSV<18 cm/s,阴茎背静脉增宽,可有血栓形成,内无血流显示或呈星点状血流信号,V<10 cm/s。结论 阴茎异常勃起具有较特征性的声像图表现,彩色多普勒超声在该病的诊断中有重要价值。 |

| Objective To assess the value of color Doppler ultrasonography for priapism (PP). Methods Sixteen patients with priapism were examined by ultrasonography. The ultrasonic sign were analyzed retrospectively. Results There were two basic types of priapism: non-ischemic (high flow, NIPP) and ischemic (low flow, IPP). The cavernosal artery blood of NIPP increased quickly, the peak systolic velocity (PSV) >40 cm/s. Corpora cavernosal inside of the posttraumatic NIPP had haematoma or false aneurysm, combined with cavernosal arterial-sinusoids leaks. The breadth of the penis deep doral vein increased and the blood increased soon quickly, V>20 cm/s. The corpora cavernosal echo in IPP at any time an extension the inside echo was gradually the asymmetry. The cavernosal artery blood turned down soon, PSV<18 cm/s. The breadth of penis deep dorsal vein increased, the inside had no blood manifestation or reports to break continuously form blood signal, V<10 cm/s. Conclusion The priapism have special ultrasonographic manifestations, color Doppler ultrasound plays important role in the diagnosis of priapism. |
