夜间阴茎勃起监测对阳萎的诊断价值

Diagnosis value of nocturnal penile tumescence analysis in impotence

目的和方法:为探讨夜间阴茎勃起(nocturnal penile tumescence,NPT)监测对阳萎的诊断价值,应用性功能微机监测系统对65例阳萎患者及15名健康志愿者进行NPT监测。结论:器质性阳萎组的阴茎相对膨胀程度和勃起维持时间两项指标均明显低于正常对照组和心理性阳萎组(P<0.01);心理性阳萎组的上述指标与对照组间无统计学差异(P>0.05)。NPT分析与病因诊断符合率为87.7％(57/65)。结论:NPT分析可作为无创伤性客观检查手段用于阳萎的诊断。

NPT analysis was evaluated in 65 cacs of impotence and 15 normal volunteers. The results showed that the penile amplification index and duration of each erection in the organic impo-tence group were much lower than that of the psychogenic and volunteer group( P <0.01)yet there has been no signicant difference between psychogenic and volunteer groups( P >0.05), The diagno-sis corresponding rate of NPT analysis was 87.7 % (57/65 ) .
