• Between July 1972 and November 1975, a total of 74 cadaver kidneys were preserved by hypothermic pulsatile perfusion using the Belzer L1-400. The initial 45 kidneys were perfused with cryoprecipitated plasma (CPP) and the subsequent 29 kidneys with plasma protein fraction (PPF). In the CPP group, 24 kidneys (53.3%) achieved immediate function, and graft survival at one and six months was 68.8% and 42.2%, respectively. In the PPF group, 14 kidneys (48.2%) achieved immediate function, with graft survival at one and six months 65.5% and 48.2%, respectively. The theoretical advantages of PPF include freedom from risk of hepatitis, absence of gamma globulin with its potential for immunologic damage to the kidney, and time saved in preparation. Our clinical experience shows that PPF is as effective as CPP as a perfusate in preservation of kidneys for transplantation.
