Most kidney grafts are marginal and from deceased donors, which yield worse clinical outcomes. Hypothermic machine perfusion has created a paradigm shift in kidney preservation. This mini-review summarizes the main points of hypothermic machine perfusion of kidney transplants that should be known by any physician and surgeon involved with kidney transplantation. Specifically, this review explains a proposed mechanism of action of hypothermic machine perfusion of kidney transplants. This review also describes the clinical effectiveness of hypothermic machine perfusion and explains how to evaluate and predict graft functionality according to machine parameters and perfusate biomarkers. Finally, treatment options and the most recent studies on oxygenated hypothermic machine perfusion are mentioned.
