Abstract:
OBJECTIVETo study the diagnostic value of color Doppler ultrasonography(CDUS) and nocturnal electrobioimpedance volumetric assessment (NEVA) in the assessment of erectile dysfunction (ED) and in differentiating the causes of ED.
METHODSCDUS and NEVA were performed in the 45 patients with ED. The patients were classified into 3 groups according to their results of CDUS, and compared all parameters of NEVA between each two groups, and then studied the correlation between CDUS and NEVA in the assessment of ED.
RESULTSIn the non-vasculogenic ED group, 17 (94.4%) patients had normal nocturnal penile tumescence (NPT); and in contrast, there were 9(75.0%) and 8(72.7%) patients with abnormal NPT in the arteriogenic and venogenic ED groups, respectively. Except that the blood volume change of penis in the venogenic ED group was significantly lower than that in the non-vasculogenic ED group (P = 0.033), there were no significant difference in the other parameters of NEVA between each two groups.
CONCLUSIONThe results of NEVA are well correlated with the functions of artery and venous which were indicated by CDUS. NEVA can indicate the causes of ED to some extent.
