检测26例勃起功能障碍（ED）病人的阴茎微循环，与17例健康志愿者进行比较，器质性ED病人阴茎头微血管密度为271±5．2，健康者为47．8±6．2（P＜0．01）；异常微血管百分率则分别为32．1±3．4与12．8±1．3（P＜0．01）；心理性ED病人该两项指标与对照组相比没有统计学差异（血管密度47．2±6.8vs47．8±6．2．P＞0．05；异常血管百分率13．1±1．1vs12．8±1．3．P＞0．05）。以上结果揭示，阴茎头微循环障碍与ED病人的器质性改变有关，可用于器质性ED的辅助诊断。
The penile microcirculation of 26 erectile dysfunction (ED) patients was detected and compared with 17 healthy volunteers. The microvessel density of penile head in organic ED patients was 271 ± 5.2, and that of healthy controls was 47.8 ± 6.2 (P <0.01). The percentage of abnormal microvessels were 32.1 ± 3.4 and 12.8 ± 1.3, respectively (P <0.01). Compared with the control group, the two indicators of psychological ED There was no statistical difference (vessel density 47.2 ± 6.8 vs 47.8 ± 6.2; P> 0.05; abnormal vessel percentage 13.1 ± 1.1 vs 12.8 ± 1.3. P> 0.05). The above results revealed that the microcirculation of the penis head and the ED patients with organic changes related to the diagnosis of organic ED can be used.
