Higher Renal Allograft Function in Deceased-Donor Kidney Transplantation Rather Than in Living-Related Kidney Transplantation.

Objectives: To compare the clinical outcome of kidney transplantation from living-related and deceased donors.
Patients and Methods: Consecutive adult kidney transplants from living-related or deceased donors from February 2004 to December 2015 in a single center were enrolled for retrospective analysis. Estimated glomerular filtration rate (eGFR) was compared with linear mixed models controlling the effect of repeated measurement at different time points.
Results: There were 536 living-related and 524 deceased donor kidney transplants enrolled. The 1-year, 3-year, and 5-year graft survival rates were 98.8%, 98.5% and 97.2% in living-related kidney transplantation (KTx), and 94.9%, 91.3% and 91.3% in deceased donor KTx (log-rank, P < .001). A significantly higher incidence of delayed graft function (DGF) was observed in deceased donor KTx (20.6% vs 2.6%, P < .001). eGFR in deceased donor KTx was significantly higher than that in living-related KTx (68.0 ± 23.7 vs 64.7 ± 17.9 mL/min/1.73 m ² at 1 year postoperation, 70.1 ± 23.3 vs 64.3 ± 19.3 mL/min/1.73 m ² at 2 years postoperation, and 72.5 ± 26.2 vs 65.2 ± 20.4 mL/min/1.73 m ² at 3 years postoperation; P < .001). The donor age was significantly higher in living-related KTx group (47.5 ± 11.0 vs 31.1 ± 14.4 years, P < .001).
Conclusion: Living-related graft survival is superior to deceased graft survival at this center, while better 5-year renal allograft function is obtained in deceased donor KTx patients, which may be attributable to the higher age of living-related donors.
