To evaluate the 5-item version of the international index of erectile function (IIEF-5) as a method to differentiate the causes of vasculogenic erectile dysfunction (ED).
In all, 103 ED patients (mean age 46.8 +/- 18.7) were reviewed by IIEF-5. Penile blood flow was also assessed in each patient after an intracavernosal injection (ICI) and audio-visual sex stimulation by duplex Doppler ultrasonography. The 99mTc-(113m)In dual radioisotope test was performed to confirm specific vascular causes in the vasculogenic ED cases. Kruskal-Wallis TEST was employed to compare the scores of IIEF-5 with the results of ICI, duplex Doppler ultrasonography and the 99mTC-(113m)In dual radioisotope test.
Of the total number of ED cases, 37 (37/103, 35.9%) were nonvasculogenic, 18 (18/103, 17.5%) arteriogenic, 35 (35/103, 34.0%) venogenic and 13 (13/103, 12.6%) combined vasculogenic. There was no significant difference in the IIEF-5 scores either between the vasculogenic group and the non-vasculogenic one (P = 0.253) or among different groups of the vasculogenic ED patients.
IIEF-5 cannot be used as a tool for differential diagnosis of vasculogenic ED, or to compare its specific vascular causes, nor can the scores of IIEF-5 reflect penile vascular conditions.
评估国际勃起功能指数5项问卷（IIEF-5）作为区分血管性勃起功能障碍（ED）病因的一种方法。
采用IIEF-5对103例ED患者（平均年龄46.8±18.7岁）进行评估。在海绵体内注射（ICI）及视听性刺激后，通过双功多普勒超声对每位患者的阴茎血流进行评估。对血管性ED病例进行99mTc-(113m)In双放射性核素检查以确定具体血管病因。采用Kruskal-Wallis检验比较IIEF-5评分与ICI、双功多普勒超声及99mTC-(113m)In双放射性核素检查结果。
在所有ED病例中，37例（37/103，35.9%）为非血管性，18例（18/103，17.5%）为动脉性，35例（35/103，34.0%）为静脉性，13例（13/103，12.6%）为混合性血管性。血管性组与非血管性组之间（P = 0.253）以及血管性ED患者不同组之间的IIEF-5评分均无显著差异。
IIEF-5不能用作血管性ED鉴别诊断的工具，也不能用于比较其具体血管病因，IIEF-5评分也不能反映阴茎血管状况。
