Randomization and blinding

Computer-generated randomized lists will be drawn up before the onset of the study using a permuted block design, under the responsibility of the Clinical Research Unit (Unité Aide Méthodologique à la Recherche Clinique, AP-HM, France). Randomization (1:1 allocation ratio) will be stratified by center (n = 16) and the number of kidneys per donor (two modalities, one or two). Randomization is centralized, web-based and accessible 24 h a day according to the allocation list. A randomization number will be allocated to each patient. The intensivist and the nurse in charge of the donor with a beating heart will be blinded regarding the allocation of treatment (preparation by an intensive care unit (ICU) nurse or a clinician not in charge of the donor). The statistician, the transplanted patients and the clinicians in charge of the transplanted patient will all be blinded concerning the treatment allocation.
