The Korean Network for Organ Sharing (KONOS), which was established in December 31st, 1999, is a nationwide system of deceased donor detection and distribution. From its inception, KONOS has defined marginal donors and used this definition for over 15 years. However, this definition should be reevaluated to determine if it requires revision. This study was conducted to confirm the feasibility of the main study for revision of the marginal donor definition in deceased donor kidney transplantation.
This study is a retrospective meta-analysis of 786 patients who had deceased donor kidney transplant from six centers. After the data validation process, multivariable analysis was conducted to evaluate whether the marginal donor criteria of KONOS or UNOS expected adequately in terms of graft survival and delayed graft function (DGF).
Neither the KONOS or UNOS criteria affected graft survival. Expanded criteria for donors of UNOS was a risk factor for DGF. However, KONOS criteria did not affect DGF.
Based on this preliminary study, there is a need to conduct a study to revise the marginal donor criteria of KONOS in deceased donor kidney transplantation. Such a study should have large scale and long-term follow-up data.
