夜间阴茎勃起测定系统筛选勃起功能障碍病人的临床应用

Nocturnal Electrobioimpedance Volumetric Assessment of Patients with Erectile Dysfunction

目的 :探讨应用尼娃牌 (NEVA)夜间阴茎勃起测定系统筛选勃起功能障碍 (ED)的可行性及意义。 方法 :2 0例门诊ED病人 ,睡前正确粘贴NEVA测定仪电极 ,带机过夜 ,次日数据回放输入主机分析。 结果 :全部病人均可耐受测定 ,依从性好 ,15例病人资料提示阴茎无器质性疾病 ,4例提示阴茎动脉供血不足 ,1例可疑阴茎静脉漏 ,3种病例勃起事件分别为 ( 4 .0± 0 .4 )、( 3 .2± 0 .3 )、( 2 .0± 0 )次 ,阴茎截面积最大改变量分别为( 0 .178± 0 .0 18)、( 0 .0 80± 0 .0 0 4 )、( 0 .13 5± 0 )cm2 ,平均勃起状态阴茎血容量分别为基准水平的 ( 2 2 5 .5± 12 .0 ) %、( 14 5 .2± 10 .6) %、( 12 8.0± 0 ) %。 结论 :尼娃牌夜间阴茎勃起测定系统操作简便、易行、无创伤 ,可区分心理性、血管性ED。

s: Objectives: To evaluate the clinical effect of nocturnal electrbioimpedance volumetric assessment on erectile dysfunction patients. Methods: Twenty out patients of primary diagnosis of erectile dysfunction were examined. The three electrodes were placed correctly before sleep. The recorder was comfortably warmed on the upper thigh. The results were retrieved and analyzed in the next morning. Results: All the patients had the examination safely. Fifteen cases showed no quality diseases in the penis. Four cases were considered as artery insufficient.One cases was considered as veno occlusive. The erectile events were (4.0± 0.4) ,(3.2± 0.3 ),(2.0 ±0),cross area change (0.178± 0.018),(0.080 ±0.004),(0.135 ±0)cm 2 , and the volume change over baseline (225.5 ±12)%, (145.2 ±10.6)%,(128.0 ±0)%,respectively. Conclusions: The present study demonstrates that the electrobioimpedance volumetric assessment is feasible, non invasive, and easy to operate. It can discriminate the psychic ED and the blood vessel ED of different reasons.
