Cold ischemia time (from flush to out-of-ice) and warm ischemia time (from out-of-ice to
reperfusion) are known to impact delayed graft function (DGF) rates and long-term allograft
survival following deceased donor kidney transplantation. We propose an additional
ischemia time, extraction time, beginning with aortic cross-clamp and perfusion/cooling of
the kidneys, and ending with removal of the kidneys and placement on ice on the backtable.
During this time the kidneys rewarm, suffering an additional ischemic insult, which may …
