BACKGROUND: Pre-transplantation dialysis duration and modality may affect patients' long-term (mortality and graft failure) and short-term (delayed graft function) outcomes after kidney transplantation. We aimed to assess the impact of the method and duration of dialysis therapy on the graft function in the first 6 months post-transplant.
METHODS: The analysis included 122 kidney transplant patients (109 from a deceased donor and 13 from a living donor). Before transplantation, 91 were on hemodialysis (HD), 19 were on peritoneal dialysis (PD), and 9 received preemptive transplants. The incidence of delayed graft function (DGF) and creatinine levels at discharge and 6 months after transplantation were assessed.
RESULTS: PD and HD patients did not differ in age, number of mismatches, and cold ischemia time (CIT), but they had a significantly shorter dialysis vintage (18.3 ± 25.7 vs 39.6 ± 34.3 months, P = .01) and a lower incidence of DGF (5% vs 37%, P = .006). The duration of hospitalization and creatinine concentration at discharge and after 6 months were similar. Preemptively transplanted patients had a significantly shorter CIT (ND vs DO - 576 ± 362 vs 1113 ± 574, P = .01; ND vs HD - 576 ± 362 vs 1025 ± 585 minutes, P = .01). DGF did not occur in any of the patients transplanted preemptively. They had slightly shorter hospitalization times and, compared to HD, better graft function at discharge. After 6 months, creatinine levels were comparable to HD and PD. Patients dialyzed for less than 12 months, regardless of the method, had a lower incidence of DGF.
CONCLUSIONS: Peritoneal dialysis and a short duration of pre-transplant dialysis may improve the early results of kidney transplantation.
