Background: The shortage of donor organs has been a major challenge in transplantation. In an effort to reduce the donor shortage, kidney transplantation (KT) using expanded criteria donors (ECD) was encouraged. In Korea, transplantation centers used the Korea Network for Organ Sharing (KONOS) ECD criteria, which is different from the United Network for Organ Sharing (UNOS) criteria. The aim of this study is to evaluate the predictive power of KONOS criteria on delayed graft function (DGF) in comparison to UNOS criteria. Methods: A total of 376 recipients who underwent deceased donor kidney transplantation between January 2005 and December 2014 at Severance Hospital were retrospectively reviewed. Of these, 130 cases satisfied KONOS ECD, while the others followed KONOS standard criteria donor (SCD). Results: Donor age and history of hypertension was significantly higher with KONOS ECD than with KONOS SCD. In KONOS subgroup analysis, donor characteristics were different than with UNOS criteria. The incidence of DGF was higher in the KONOS ECD group than in the KONOS SCD group. However, UNOS ECD showed a high incidence of DGF compared to UNOS SCD with the same KONOS criteria. UNOS ECD was an independent risk factor for DGF in multivariate analysis. However, KONOS ECD was not a risk factor for DGF. Although glomerular filtration rate was inferior in the KONOS ECD group compared to the KONOS SCD group, the UNOS SCD group within the KONOS ECD group showed similar graft function compared to the KONOS SCD group. Conclusion: KONOS criteria have a lower predictive power for DGF than UNOS criteria.
