【摘要】目的:評估彩色多普勒超聲聯合陰莖海綿體注射和聽覺視覺性刺激在勃起功能障礙診斷中的臨床應用價值。方法:對120例臨床診斷為勃起功能障礙的患者進行陰莖海綿體內注射血管活性藥物和輔助眼鏡式影像儀給予聽覺視覺性刺激,采用彩色多普勒超聲測量陰莖海綿體動脈直徑(CAD)、收縮期峰值流速(PSV) 、舒張末期流速(EDV) 、阻力指數(RI) 、背深靜脈(DDV) 流速。結果:非血管性、動脈性和靜脈性ED患者左右深動脈血流參數和注射前后陰莖海綿體動脈直徑增大率差異無統計學意義(P>0.05);彩色多普勒超聲聯合陰莖海綿體注射和聽覺視覺性刺激在診斷動脈性血勃起功能障礙敏感度與特異度均為100%,診斷靜脈性血勃起功能障礙敏感度為100%,特異度為96%。結論:彩色多普勒超聲聯合陰莖海綿體注射和聽覺視覺性刺激在診斷各類型血管性ED及區別非血管性ED中具有較高的臨床價值,值得推廣應用。

【Abstract】Objectives: To investigate the value of color doppler ultrasound joint intracavernous injection and visual -auditory sexual stimulation in diagnosis of patients with erectile dysfunction (ED). Methods: 120 ED patients were injected with vasoactive drugs through the corpus cavernosum and given visual -auditory sexual stimulation. The cavernosum artery diameters (CAD), peaks of the systolic velocity (PSV), the end-diastolic veloeity (EDV), resistant index (Rl) and flow rate of deep dorsal vein (DDV) were measured and compared before and after with color doppler ultrasounds. Results: Difference in left and right arterial blood flow parameters between all kinds of ED groups was not statistically significant, so as the increase in CAD after the treatment (P>0.05). Both the sensitivity and specificity of color doppler ultrasound joint intracavernous injection and visual-auditory sexual stimulation in diagnosis of arterial ED patients was 100%, and the specificity decreased to 96% in the diagnosis of venous ED patients while the sensitivity remained 100%. Conclusion: Color doppler ultrasound after intracavernous injection and visual -auditory sexual stimulation has a great value for the diagnosis of various types of vaseular ED and discrimination of non-vaseular ED, which is worthy of clinical application.

勃起功能障礙(erectile dysfunction,ED)是指陰莖受到刺激后勃起硬度不足以插入陰道或勃起維持的時間不足以滿意地完成性生活,是最常見的男性性功能障礙之一,嚴重影響患者的家庭穩定性,給患者造成具體的心理壓力[1-3]。勃起功能障礙的病因十分復雜,因此臨床治療首先要明確患者的病因,才能夠取得良好的臨床療效[4]。動脈供血不足及靜脈關閉不全以及靜脈瘺是導致器質性勃起功能障礙的較為常見的因素,彩色多普勒超聲在對血管性勃起功能障礙的診斷中具有無創、重復性好的優點,己成為臨床鑒別血管性ED的重要手段。目前……
