Donor pretreatment and machine perfusion: current views

PURPOSE OF REVIEW: To summarise recently published studies of donor pretreatment and machine perfusion strategies in kidney transplantation.

RECENT FINDINGS: The sparsity of donor pretreatment trials has resulted in the re-analysis of already existing data, and RCTs are urgently needed to reinvigorate this aspect of donor research. Uncontrolled donation after circulatory death kidney transplantation has the highest risk of delayed graft function and graft failure, and recent studies have reported that normothermic regional perfusion improves graft function and survival in this setting. Hypothermic machine perfusion reduces delayed graft function following deceased donor kidney transplantation across donor types but unanswered questions still remain regarding its use. The use of oxygenated hypothermic machine perfusion appears to improve graft function in controlled donation after circulatory death mediated by a reduction in acute rejection. Ex-situ normothermic perfusion is emerging and while technically challenging it may facilitate the delivery of pretreatments.

SUMMARY: RCTs are urgently needed to reinvigorate research into donor pretreatment and to establish the place of specific preservation techniques in deceased donor kidney transplantation.
