The negative influence of delayed renal allograft function on longer-term graft survival in a pediatric population

The influence of delayed graft function on renal allograft survival has been studied in a review of 322 renal transplants performed at one pediatric institution. The appearance of the first radionuclide renal scan was used to indicate early function in patients receiving their first cadaveric allograft. Patients whose first radionuclide renal scan showed both good renal perfusion and good function (n = 52) were compared with those whose scans demonstrated good perfusion but no function (n = 32). the actuarial graft survival of those with no function was significantly worse (P < .05). The difference in graft survival was not solely due to grafts lost in the early posttransplant period. Analysis of serial serum creatinine estimations suggests a process of continued inexorable nephron loss in some patients whose grafts showed a delay in achieving function.
