肾移植后肾功能测值与肾血流灌注相关性分析

目的探讨移植肾功能测值与肾血流灌注相关性及临床意义.方法采用彩色能量图(CDE)对1 100例移植肾患者进行术后监测和追踪.根据肾内血流灌注情况将CDE分为4级,同时取患者当天的尿和血进行实验室检查.结果肾功能测值与CDE肾内血流灌注级别密切相关,而移植肾的排异反应与CDE肾内血流灌注级别及肾功能测值变化也密切相关.结论CDE提供了更为丰富的肾血流灌注信号,较彩色多普勒血流显像(CDFI)更为敏感,其反应的肾灌注情况与肾功能测值成正相关并能适时反应移植肾排异反应.

Relationship between renal function and renal blood perfusion after kidney transplantation

Objective: To evaluate the relationship between renal function and renal blood perfusion, and to evaluate its clinical significance. Methods: The renal blood perfusion of one thousand and one hundred patients were assessed by CDE after kidney transplantation. CDE was graded into 4 grades according to the perfusion, and the samples of urine and blood were also tested on the same day. Results: The indexes of renal function were significantly correlated with the grade of CDE, rejections after transplantation were also significantly correlated with the grade of CDE and correlated with the change of renal function. Conclusion: CDE provides more abundant signals of renal blood perfusion, and it is more sensitive than CDFI. The perfusion of renal was positively correlated with the renal function, and CDE can also reflect the rejection early.
