The incidence and risk factors of delayed graft function in 689 consecutive living unrelated donor renal transplantation.

Due to the severe shortage of deceased donor kidneys, the number of renal transplantation from living-related and living-unrelated donors has increased worldwide. The incidence and risk factors of delayed graft function after deceased donor renal transplantation have been extensively studied. In this analysis, the incidence and predictors of delayed graft function was investigated in 689 living-unrelated kidney recipients. In 53 recipients, dialysis was needed within the first week after renal transplantation (7.7%). The risk factors for delayed graft function upon univariate analysis models were: female gender of kidney donor (P=.027), renal allograft with multiple arteries (P=.005) and previous transplantation (P<.005). Upon multivariate analysis, the only risk factor for development of delayed graft function was retransplantation (P=.001).
