Objective. The objective of this study was to evaluate the risk factors for delayed graft function (DGF) and their influence on renal graft outcome. Patients and Methods. We reviewed 1462 consecutive renal transplantation and identified 245 patients (17.1%) with delayed graft function and 1120 patients with immediate graft function. Forty-one cases were excluded because of a nonfunctioning graft as well as 26 other cases because of insufficient data. We compared the incidence, donor and recipient risk factors, and impact on graft outcomes, as well as patient and graft survival of delayed graft function. Results. Donor weight and age, recipient weight, age, length of dialysis, and cold ischemia time were significantly higher in the delayed graft function group. Higher rates of acute rejection and chronic graft dysfunction were observed in this group of patients; we also observed worse graft function and survival. Conclusions. Multiple risk factors are associated with delayed graft function, which contribute decisively to a worse outcome.D ELAYED renal graft function is defined as the need for dialysis within the first week posttransplantation, acute tubular necrosis is its most common cause. However, the consequences far exceed the transient need for dialysis because it may interfere with long-term graft survival. Our purpose was to evaluate the risk factors for delayed renal graft function and to measure their influence on renal graft outcomes.
PATIENTS AND METHODSWe retrospectively studied 1462 consecutive renal transplantations performed between 1980 and 2005. All relevant data concerning the donor, the recipient, and the transplantation were inserted into a database. The percentages of patients with immediate diuresis versus delayed graft function (DGF) were calculated. We evaluated risk factors for the occurrence of DGF, either donor-related or recipient-related. Also, the patient and graft survival rates, as well as long-term renal function, were evaluated.Of the 1462 procedures, we excluded 41 cases (2.8%) of never-
