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。
To investigate the characteristics of penile microcirculation in men with erectile dysfunction (ED). Penile microcirculation was detected in 26 erectile dysfunction patients and compared with 17 healthy volunteers. The results showed that the microvessel density (27.1 ± 5.2, 47.8 ± 6.2) and the percentage of abnormal microvessels (32.1 ± 3.4) in control group were significantly higher than those in control group. 8 ± 1.3) were significantly different from the control group, P <0.01; these two indicators of psychological ED patients compared with the control group was no significant difference (blood density 47.2 ± 6.8, control group 47.8 ± 6.2; the percentage of abnormal blood vessels was 13.1 ± 1.1, and the control group was 12.8 ± 1.3, all P> 0.05). CONCLUSION: Erectile dysfunction in patients with organic ED is related to the change of penis microcirculation. The clinical significance needs further study. The penis microcirculation test can be used to diagnose organic ED.
