彩色多普勒超声检查在血管性勃起功能障碍诊断中的应用

目的:评估彩色多普勒超声在诊断血管性勃起功能障碍中的临床价值。方法:应用彩色多普勒超声技术,检测527例疑似血管性勃起功能障碍患者,海绵体注射血管活性药物前、后阴茎海绵体动脉血流动力学。结果:动脉性勃起功能障碍207例(49.88%),静脉性勃起功能障碍144例(34.70%),动静脉性勃起功能障碍64例(15.42%),非血管性勃起功障碍112例(26.99%)。结论:彩色多普勒超声技术是目前诊断血管性勃起功能障碍的一种微创而可靠的检查方法,其能够定量反映阴茎的血流动力学状态,为合理的治疗勃起功能障碍提供有价值的依据。

The Value of Dynamic Color Duplex Scanning in the Diagnosis of Vascular Erectile Dysfunction

OBJECTIVE: To evaluate deep penile arterial flow after an intracavernosal injection with prostaglandin E1 in patients with erectile dysfunction (ED). METHODS: 527 patients with ED were evaluated using Color Doppler Ultrasonography. Diagnostic tests were undertaken after an intracavernosal injection with 20 microg prostaglandin El. The peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) were analysed. RESULTS: There were 112 patients (26.99%) with nonvasculogenic ED, 207 patients (49.88%) with arteriogenic ED, 144 patients (34.70%)with venogenic ED, 64 patients (15.42%)with mixed ED. CONCLUSION: The Color Doppler Ultrasonography technique allows accurate location and evaluation of deep penile arteries. Vascular pathology may be differentiated after an intracavernosal injection with a vasomotor agent. Recognising the pathological pattern assists in choosing the best method of treatment.
