目的 探讨不同硬度状态阴茎血管血流参数的差异,为阳萎分度诊断提供客观依据。方法应用多普勒超声检测74例阳萎患者,海绵体注药前后,连续测定海绵体动脉及背动脉收缩期峰值流速(PSV)、舒张期末血流速度(EDV)、阻力指数(RI)和背深静脉血流速度,对比分析不同硬度诸参数的差异及与硬度的关系。结果 多普勒超声根据海绵体动脉PSV减小及EDV升高,并同硬度结合可以推断海绵体动脉和静脉异常;海绵体动脉PSV、EDV、RI在不同硬度有显著性差异(P<0.05),RI与硬度密切相关(r′s=0.7948,P<0.01),可作为阳萎分度诊断的客观指标。
Objective To study the difference of penile vascular parameters under different penis stiffness state in order to provide objective information for diagnosis of impotence grading.Methods Seventy four cases of impotence patients were examined by color Doppler flow imaging(CDFI).Before and after drug injection of cavernosum,the PSV,EDV,RI of cavernosal artery and velocity of dorsal vein were measured continously at the time interval of 5 min,and were compared with penis stiffness state.The difference of the vascular parameters and the correlation between the vascular parameters and penis stiffness were analysed under different penis stiffness.Results By combinating the PSV decrease and EDV increase of cavernosal artery with penis stiffness,the abnormalities of cavernosal artery and dorsal vein may be found.Under different penis stiffness state the PSV,EDV,RI of cavernosal artery have significant difference (P< 0.05 ).The RI correlated closely with the penis stiffness state (r′ s= 0.7948 ).RI may provide objective data for the diagnosis of impotence grading.Conclusions CDFI is regarded as the valuable method in the diagnosis of impotence grading.
