RESUMO
BACKGROUND: In kidney transplantation (KT), delayed graft function (DGF) is a significant early complication observed in the first week. The study aimed to investigate the impact of DGF on the outcome, allograft, and patient survival after KT with organs from deceased donors. METHODS: This retrospective study was conducted using 304 KT patients who received an organ from deceased donors from 2008 to 2018. The patients were divided into 2 groups, DGF positive (DGF+) and DGF negative (DGF-). The database containing the clinical, laboratory, and immunologic information of donors and recipients was statistically analyzed using the SSPS program. RESULTS: In this study, 189 (62.17%) were DGF+ and 115 (37.83%) were DGF-. Until 6 months after KT, the estimate glomerular filtration rate was better in group DGF-, but it was similar between the groups during 10-year follow-up. Graft losses were higher in DGF+ group than in the DGF- (P = .046). The serum creatinine level was persistently higher in DGF+ group until the sixth month (P ≤ .05). Allograft survival rates were better in patients who were DGF- (P = .033). Those who had DGF for more than 15 days had a worse graft survival (P = .003), but in 10 year follow-up, patient survival rates were similar (P = .705). CONCLUSION: DGF+ patients were associated with dialysis time before KT, ischemia time, and the donors' clinical status, such as age, organ quality, and serum creatinine. All these factors had a great impact on graft survival but not on patient survival.
