RESUMEN
To increase the utilization rate of expanded criteria donor (ECD) kidney, the kidney preservation methods have been ever advancing in recent years. The application of normothermic machine perfusion (NMP) promotes the preservation, evaluation and repair of ex vivo donor kidneys and accelerates the innovation of surgical approaches of kidney transplantation. Ischemia-free kidney transplantation (IFKT), which initiated by Organ Transplantation Center of the First Affiliated Hospital of Sun Yat-sen University, keeps the blood flow and oxygen supply of the donor kidney with NMP machine during the entire process of acquisition, preservation and transplantation, thereby fundamentally avoiding ischemia-reperfusion injury (IRI) of the donor kidney and reducing the risk of delayed graft function (DGF) and acute rejection after surgery. In this article, recent progresses upon the kidney NMP, surgical procedures and short-term outcomes of IFKT were reviewed, aiming to provide reference for enhancing the utilization rate of ECD donor kidney and resolving the issue of organ shortage.
RESUMEN
Full application of marginal donor organs is a critical method to expand donor pool and alleviate organ shortage. After accurate donor evaluation, allocation and recipient selection, adult donor dual kidney transplantation (DKT) can not only achieve equivalent clinical efficacy to single kidney transplantation (SKT), but also effectively reduce the discard rate of marginal donor kidney. In this article, the clinical application and progress on adult donor DKT were reviewed from the perspectives of the development situation, allocation standard, recipient selection, surgical methods and complications as well as clinical efficacy of DKT, aiming to provide reference and guidance for subsequent development of marginal donor DKT.
