Objective   To compare the early clinical efficacy of renal transplantation between extended criteria donor (ECD) and standard criteria donor (SCD).

  Methods   Clinical data of 85 recipients undergoing renal transplantation from donation after cardiac death (DCD) were retrospectively analyzed. According to the types of donors, all recipients were divided into the ECD group (n=31) and SCD group (n=54). The level of serum creatinine (Scr), incidence of early complications and clinical prognosis within 3 months after renal transplantation were compared between 2 groups.

  Results   No statistical significance was observed in the levels of Scr within 1 month after renal transplantation between the ECD group and SCD group (all P > 0.05). At postoperative 60 and 90 d, the level of Scr in the ECD group was (189±97) and (175±69) μmol/L respectively, significantly higher than (142±49) and (135±41) μmol/L in the SCD group (P=0.005 and 0.002). In the ECD group and SCD group, the incidence of acute rejection (AR) was 6% and 15%, the incidence of delayed graft function (DGF) was 23% and 19%, the incidence of pulmonary infection was 10% and 6%, the incidence of other early complications was 32% and 15%, respectively, no statistical significance was identified (all P > 0.05). In the ECD group and SCD group, the survival rate of the recipient was 97% and 94%, the survival rate of the renal was 84% and 91%, no statistical significance was identified (all P > 0.05).

  Conclusions   Compared with the SCD, renal transplantation from ECD can achieve equivalent early clinical efficacy. In the present condition of serious deficiency of donor kidney, the application of ECD can enlarge the supply of the donor kidney.
