肾移植术后导致肾功能恢复延迟的危险因素分析

目的探讨肾移植术后发生肾功能恢复延迟(DGF)的危险因素。方法对肾移植术后发生DGF的111例患者(DGF组)及同期未发生DGF的141例患者(对照组)的临床资料进行回顾性分析,用χ2检验进行单因素分析,用Logistic进行多因素回归分析,计算其相对危险度。结果单因素及多因素分析表明,冷缺血时间,热缺血时间,术中、术后早期低血压,群体反应性抗体阳性,急性肾小管坏死,加速性排斥反应,神经钙调素抑制剂肾毒性,术后早期尿漏、输尿管梗阻等8种因素是发生DGF的危险因素。结论术前、术中及术后早期的多种因素均能导致DGF,其发生基础为缺血-再灌注损伤,应针对多种危险因素采取综合预防措施。

Analysis on the risk factors for delayed graft function in cadaveic kidney transplantation

Objective To investigate the risk factors for delayed graft function (DGF) under-(going) cadaver renal transplantation.Methods Twenty-four relative variables were analyzed by SPSS11.0 statistical software. Using chi-square analysis method, the influence of these variables on DGF was retrospectively studied. Logistic regression analysis was done to assess and rank the relative risk of potential variables.Results The overall incidence of DGF was 5.01 %. Chi-square analysis (revealed) that the risk factors for DGF were identified as: cold ischaemia time, warm ischaemia time, recipient hypovolaemia, number of previous transplants, allosensitisation of the recipient, ATN, (accelerated) rejection, cyclosporine nephrotoxicity, ureteral leakage obstruction. Logistic multivariate analysis showed that there were 8 risk factors contributing to DGF.Conclusion DGF is a common (allograft) complication in the immediate posttransplant. There are many risk factors contributing to this condition. The basic change is ischemia-reperfusion injury. It is very important to comprehend the risk (factors) thoroughly in order to prevent them effectively.
