阴茎勃起功能障碍(简称ED)的病因非常复杂,其基本病机是由于阴茎海绵体平滑肌不能松弛,不足以使阴茎海绵窦血流增加,致海绵窦间隙增大而阴茎疲软,不能胀大。我院于2001年11月至2003年2月采用前列腺素E1乳膏经尿道内用药法,使用美国彩色多普勒超声显像仪观察了89例ED患者用药前后阴茎背动脉,左右海绵体动脉收缩期峰值血流速度(PSV)和海绵体周径变化。现报告如下。 The etiology of penile erectile dysfunction (ED) is very complex, the basic pathogenesis is due to the cavernous smooth muscle can not be loosened, not enough to make penile cavernous sinus blood flow increases, resulting in increased cavernous sinus gap and penile weakness, can not swell. In our hospital from November 2001 to February 2003 using prostaglandin E1 cream through the urethral medication, the use of color Doppler ultrasound imaging showed 89 cases of ED patients before and after treatment of penile dorsal artery, left and right cavernous artery Systolic peak blood flow velocity (PSV) and changes in corpus cavernosum. The report is as follows.
