Is pulsatile perfusion necessary for renal transplantation engrafting kidneys from cardiac death donors?
BACKGROUND
There has been a considerable literature describing the use of pulsatile perfusion (PP) to evaluate the efficacy of organs from deceased donors. Since 1979, we recovered 469 kidneys from deceased donors after cardiac death (DCDs), using an in situ regional cooling technique and preservation by simple cold storage. In this study, the posttransplantation outcomes as well as long-term survivals of renal grafts from DCDs were compared with PP data in the recent literature.


METHODS
We compared our recent data with 176 kidneys recovered between 1993-2002 using an in situ regional cooling technique. Patient and graft survivals were compared with those from the Scientific Registry of Transplant Recipients (SRTR) database.


RESULTS
Following transplantation, 4.5% of the grafts never recovered; 10.3% of the grafts showed immediate renal function; 85.2% of the grafts had delayed graft function (DGF) with an average acute tubular necrosis (ATN) period of 13.1 days compared with 54.3% DGF from DCD using PP. Graft survival rates at 1, 3, 5, and 10 years were 90.8%, 86.5%, 77.8%, and 69.0%, respectively, compared with 89% at 1 year and 80% at 3 years reported for DCD by the SRTR in which almost 30% of the grafts underwent PP.


CONCLUSIONS
Although PP seemed to have some advantage to decrease the DGF ratio, an in situ regional cooling technique with simple cold storage may provide excellent graft function and long-term graft survival as well as having benefits in cost and transportation.
