Long-term results of 1047 cadaveric kidney transplantations with special emphasis on initial graft function and rejection.
We studied the effect of initial graft function and acute rejection on graft survival in 1047 cadaveric renal transplantations during 1991-1997 with a constant policy of donor selection, graft allocation, and immunosuppression. The overall 1- and 5-year patient survival rates were 96 % and 88 %, and the 1- and 5-year graft survival (GS) rates were 92 % and 78 %. Delayed graft function (DGF) occurred in 31 % and there were 1.2 % never-functioning grafts. One-year GS in transplantations with early graft function (EGF) was 95 % compared to 87 % in DGF (P < 0.001). Donor age and cause of death, type of graft perfusion and cold ischemia time, and type and length of dialysis treatment were significant factors in determining the onset of graft function. These factors did not have a significant direct effect on GS. Early ( < 100 days) acute rejection occurred in 25 %. In transplantations without rejection, the 1 and 5-year GS was 93.3 % and 80.8 %. In acute rejection responding to steroids, the GS was equal to that up to 3 years, but after that a significantly worse survival rate was observed (1- and 5-year GS: 93.6 % and 73.4 %). DGF was detrimental to GS both in transplantations without rejection and in all rejection types.
