Abstract:Maintaining the vitality of the donor kidney during organ preservation is the prerequisite and the fundamental guarantee for successful organ transplantation. At present, cold storage (CS) is still the preferred and the most commonly used preservation method in the majority of organ transplant centers. With the increasing demand for donors, more and more elderly and marginal donors have been used in clinical practice, which puts higher demands on traditional organ preservation approaches. This review focuses on the latest progress in organ preservation solutions and machine perfusion for kidney transplantation.
