Intermittent Versus Continuous Surface O2 During HMP of DCD Kidneys

Kidneys originating from deceased donors after circulatory death (DCD), category 3 and 5 (controlled) will be preserved from procurement until transplantation on hypothermic machine perfusion conditions and prospectively randomized into 2 study groups: 1) intermittent surface oxygenation during HMP (surface oxygenation interrupted during organ transport (2-4h)(I-HMPO2 group), and 2) continuous surface oxygenation during HMP (surface oxygenation during the whole machine preservation period included organ transport)(C-HMPO2 group).
