我院１９８８年以来采用脑电ｔ检验地形图，对３５例尿毒症和２０例肾移植患者手术前后脑电地形图异常分布进行了统计学成象分析。结果发现尿毒症期脑电广泛异常分布是有意义的（Ｐ＜０．０１），慢波功率增加最显著的区域为右顶部，ａ波功率减少最明显为顶区偏右部，表明尿毒症期的脑损害既有广泛性损害的一般性，又有局限性损害的特殊性，且病变最重为某一区域，这种特征随着尿毒症病程延长而加重，一旦接受肾移植，随着移植肾功能恢复，血中代谢性产物清除，脑组织和脑脊液中内环境得以平衡稳定，脑电地形图很快恢复正常。
In our hospital since 1988 using EEG t test topographic maps of 35 cases of uremia and 20 cases of renal transplant patients with abnormal distribution of EEG before and after the statistical imaging analysis. The results showed that uremic encephalon widespread abnormal distribution is significant (P <0.01), slow wave power is the most significant increase in the area at the top of the top, a wave power reduction is most obvious top area to the right, indicating that uremia Period of brain damage both extensive general damage, there are limitations of the particularity of damage, and the lesions as the most important for a region, this feature with uremia longer duration of illness and aggravated, once accepted renal transplantation, with the Transplantation of renal function recovery, removal of blood metabolites, brain and cerebrospinal fluid in the balance of the internal environment, EEG topography quickly returned to normal.
