Kidney transplant patients can be divided into three groups, according to the initial graft function. First-week dialyzed patients form the delayed graft function (DGF) group. Nondialyzed patients are divided into slow graft function (SGF) or immediate graft function (IGF) according to whether the day 5 serum creatinine was higher versus lower than 3 mg/dL, respectively. SGF patients showed worse graft survival, above higher incidence of acute rejection and lower renal function than IGF patients, although few reports have analyzed outcomes in these groups. We analyzed the impact of SGF on graft survival, first-year renal function, and incidence of acute rejection in 291 renal transplant patients. Creatinine was significantly worse at 12 months for SGF and DGF than for IGF patients (1.9 +/- 0.8 mg/dL, 1.8 +/- 0.7 mg/dL, 1.5 +/- 0.5 mg/dL, respectively; P < .05). There was no difference in first-year renal function between SGF and DGF. The acute rejection rate was higher among the SGF than the IGF group (45% vs 21%, P < .05), but not different from DGF patients (42%, P < .05). Graft survival was better among IGF than SGF or DGF patients, with no significant difference between the last two groups (3-year graft survival, 82%, 71%, 70%, respectively; log-rank test, P < .05). Kidney transplant recipients who develop SGF have a worse outcome than patients with IGF, similar to DGF patients. SGF patients show worse graft survival, worse renal function, and higher acute rejection rates than IGF patients, despite not needing dialysis.
