男子勃起功能障碍患者阴茎微循环检测

Microcirculation of penile erectile dysfunction

为了探讨男子勃起功能障碍（ＥＤ）患者阴茎微循环特点。检测２６例勃起功能障碍患者的阴茎微循环，与１７例健康志愿者进行比较。结果表明：器质性ＥＤ患者阴茎头微血管密度（２７．１±５．２，对照组为４７．８±６．２）和异常微血管百分率（３２．１±３．４，对照组为１２．８±１．３）均明显异于对照组，Ｐ＜０．０１；心理性ＥＤ患者的这两项指标与对照组相比没有统计学差别（血管密度４７．２±６．８，对照组为４７．８±６．２；异常血管百分率１３．１±１．１，对照组为１２．８±１．３，Ｐ均＞０．０５）。结论：器质性ＥＤ患者的勃起功能障碍与阴茎头微循环改变有关，其临床意义有待深入研究，阴茎头微循环检测可用于器质性ＥＤ的辅助诊断。

Objectives:The characteristics of penile microcirculation were investegated in patients with erectile dysfunction (ED).Methods:Penile microcirculation of 26 cases of patients with ED were observed and compared with 17 cases of healthy donors.Results:Both microvessel density (27.1±5.2 vs.47.8±6.2 P<0.01 ) and microvessel deformity rate (32.1±3.4 vs.12.8±1.3 P<0.01 ) were significantly different in patients with organic ED and control subjects, and there were no significantly different in patients with psychological ED and control subjects.Conclusion:The changes of penile microcirculation are related to the changes of organic in patients with ED,but this changes of organic of clinical utility need future study.Penile microcirculation may be used as an index for organic ED.
