药物性阴茎双功能超声检测在外伤性勃起功能障碍中的应用

目的 探讨阴茎双功能超声诊断尿道外伤患者勃起功能障碍的价值.方法 尿道外伤后经IIEF-5评分诊断为勃起功能障碍的患者35例分别于注射罂粟碱及酚妥拉明前后应用多普勒超声测量阴茎背动脉和背深动脉的动脉血流收缩期峰速(peak systolic velocity ,PSV),舒张末期流速(end diastolic velocity,EDV),阻力指数(resistance index,RI);背深静脉流速(V),并进行组间分析.依据骨盆耻骨联合有无分离分为两组,分离组13例,未分离组22例.结果 35例勃起功能障碍的患者中,经超声诊断为血管性勃起功能障碍(erectile dysfunction,ED)的有11例,耻骨联合分离组与未分离组在注射血管活性药物后背深动脉收缩期流速有统计学意义(P《0.05).结论 阴茎血流超声检测在诊断尿道外伤患者勃起功能障碍时可对血管性ED作出诊断,后尿道损伤患者尤其是合并骨盆耻骨联合分离者可能存在较大的血管性ED的风险.

Pharmacopenile Doppler ultrasonograpgy in the diagnosis of urethral trauma associated with erectile dysfunction

Objective To study the value of pharmacopenile Doppler ultrasonograpgy in the diagnosis of urethral trauma associated with erectile dysfunction.Methods Method 35 patients who suffered from the urethral trauma associated with erectile dysfunction were tested with international index of erectile function-5(IIEF-5).Pharmaco penile Doppler ultrasonograpgy(PPUD) was performed before and after intracavernosal injection of Papaverine.Peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI) of the cavernosal artery and deep cavernosal artery were measured;and vein velocity(VV) were determined for deep dorsal vein.According to with or without pubic symphysis diastasis the patients were divided into two separate groups and compared with each other.Results Eleven patients had obviously evidences of erectile dysfunction proved by PPUD in 35 patients.Peak systolic velocity of deep cavernosal artery measured after intracavernosal injection of Papaverine were significantly different between patients with pubic symphysis diastasis and those without symphysis diastasis(P<0.05).Conclusion PPUD was an efficient method for the diagnosis of vascular ED.And traumatic sites especially in pubic symphysis diastasis may be an important correlated factor in those patients who suffered from the urethral trauma with erectile dysfunction.
