摘 要:目的观察和分析低温机械灌注(HMP)在标准供者与扩大标准供者供肾保存中的临床效果研究,总结并探讨低温机器灌注应用的适应证。方法回顾性分析2007年06月至2014年12月169例公民逝世后器官捐献(DCD)供者共255例供肾移植的临床资料。根据供肾类型不同分为标准供者组(SCD组,134例)与扩大标准供者组(ECD组,121例),ECD组根据供肾损伤原因及程度包含ECD1组(74例)和ECD2组(47例);SCD组和ECD组中又根据供肾保存方式的不同分为4组,即SCD-静态冷保存组(SCD-CS组,112例)、SCD-HMP组(22例)、ECD-CS组(63例)及ECD-HMP组(58例)。分析HMP保存对移植术后受者肾功能恢复及并发症等影响。结果SCD组及ECD1组供肾通过HMP保存后能促进早期移植肾功能恢复,主要表现为多尿期峰值提前、肌酐下降速度快;但在AR发生率、DGF发生率、出院时肌酐、移植物及受者术后1年存活率等方面与CS保存无明显差异(P〉0.05),供肾冷缺血时间及保存成本有所增加。而ECD2组供肾通过HMP保存后DGF发生率明显降低,DGF持续时间缩短,出院时血肌酐值较CS保存低;通过HMP保存虽然成本增加,但因其促进肾功能恢复,缩短住院时间,反而住院费用显著降低;然而在移植物及受者术后1年存活率等方面与CS保存亦无明显差异(P〉0.05)。结论HMP虽能一定程度上促进DCD供者供肾移植术后早期肾功能恢复,但SCD及ECD1供肾应用HMP保存使保存成本增加,无明显保存优势;而ECD2供者供肾应用HMP保存将获得更大的临床及经济学效益,是应用HMP的适应证。Objective In order to discuss and summarize the indications of hypothermic machine perfusion (HMP), to observe and analyze the clinical effects of HMP in preservation of standard criteria donors (SCD) and extended criteria donors (ECD). Methods This study retrospectively analyzed 165 pairs of donated kidneys (255 kidney transplantation cases) in the 303rd Hospital of Chinese People's Liberation Army from June 2007 to December 2014. The kidneys were divided into two groups according to different types of donated kidneys: SCD (134 cases) and ECD (121 cases). The ECD group was divided into ECD1 subgroup (74 cases) and ECD2 subgroup (47 cases) according to the causes and degrees of kidney injury. We also divided SCD and ECD into 4 subgroups according to different types of preservation methods: SCD-cold storage (CS) ( 112 cases), SCD-HMP (22 cases), ECD-CS (63 cases) and ECD-HMP (58 cases). Then we analyzed the effects of HMP on the recovery of renal function and complications after renal transplantation. Results HMP promoted the recovery of early graft in SCD group and ECD1 subgroup, mainly reflected in advancing peak in dieresis stage and faster reduction of creatinine, but there were no significant differences in the AR and DGF rate, the creatinine at discharge, 1-year survival rate of grafts and recipients between HMP and CS (P〉0. 05). HMP increased the cold ischemia time and the cost of preservation. By HMP in ECD2 subgroup, we observed a lower DGF rate, shorter DGF lasting time and lower creatinine level at discharge than by CS. HMP increased the cost of preservation but decreased the expense in hospital by promoting the recovery of renal function and shortening the hospital stay. There was no significant difference in 1-year survival rate of grafts and recipients after renal transplantation between HMP and CS (P〉0. 05). Conclusion HMP promoted the recovery of grafts in the early days to some extent but increased the cost of preservation in SC
