[Recent advances in the comprehension of the effects of cold ischemia in kidney graft].
Cold ischemia is the best known method to preserve kidneys for transplant. However, it produces several detrimental effects. First, cellular necrosis. Secondarily, during the hypothermic period a mitochondrial injury process develops which makes the cell entering a pre-apoptotic state. This apoptosis occurs definitively in the reperfusion. Preservation solutions currently available are not perfect and are not able to avoid cold-related cell injuries. The addition of certain substances to UW solution (desferrioxamine) has shown experimentally a reduction in mitochondrial cold-related lesions. Isolated hypothermic kidney perfusion reduces initial graft dysfunction about 20% in comparison to hypothermic storage. This fact relates to important either economical as functional consequences.
