Introduction: Delayed graft function (DGF) is a frequent complication after deceased donor kidney transplantation with an impact on the prognosis of the transplant. Despite this, long-term impact of DGF on graft function after deceased donor kidney transplantation has not been properly evaluated. Objective: The main objective of this study was to evaluate risk factors for DGF and the impact of its occurrence and length on graft survival and function. Methods: A retrospective cohort study was performed in 517 kidney transplant recipients who received a deceased donor organ between January 2008 and December 2013. Results: The incidence of DGF was 69.3% and it was independently associated with donor's final serum creatinine and age, cold ischemia time, use of antibody induction therapy and recipient's diabetes mellitus. The occurrence of DGF was also associated with a higher incidence of Banff ≥ 1A grade acute rejection (P = 0.017), lower graft function up to six years after transplantation and lower death-censored graft survival at 1 and 5 years (P < 0.05). DGF period longer than 14 days was associated with higher incidence of death-censored graft loss (P = 0.038) and poorer graft function (P < 0.001). No differences were found in patient survival. Conclusions: The occurrence of DGF has a long-lasting detrimental impact on graft function and survival and this impact is even more pronounced when DGF lasts longer than two weeks. Resumo Introdução: A função tardia do enxerto (FTE) é uma complicação frequente após transplantes renais com doadores falecidos com repercussões sobre o prognóstico do transplante. Contudo, o impacto a longo prazo da FTE sobre a função do enxerto após transplante renal com doador falecido não foi avaliado adequadamente. Objetivo: O principal objetivo do presente estudo foi avaliar os fatores de risco para FTE e o impacto de sua ocorrência e duração na sobrevida e função do enxerto. Métodos: O presente estudo observacional retrospectivo incluiu 517 receptores de transplante renal que receberam órgãos de doadores falecidos entre janeiro de 2008 e dezembro de 2013. Resultados: A incidência de FTE foi de 69,3%. Foi identificada associação independente entre FTE e creatinina sérica final e idade do doador, tempo de isquemia fria, uso de terapia de indução com anticorpos e diabetes mellitus do receptor. A ocorrência de FTE também foi associada a incidência mais elevada de rejeição aguda com classificação de Banff ≥ 1 A (P = 0,017), função reduzida do enxerto até seis anos após o transplante e menor sobrevida do enxerto censurada para óbito em 1 e 5 anos (P
