    Abstract:
    The impact of dialysis modality on posttransplant outcomes remains controversial. The authors have compared primary failure, delayed graft function (DGF), acute rejection episodes as well as patient and allograft survivals among patients undergoing renal transplantation between 2004 and 2009, according to the modality of hemodialysis (HD) versus peritoneal dialysis (PD). We studied 306 patients (268 HD and 38 PD) with a mean follow-up of 29 ± 16 months. The PD cohort included a predominance of females (68.4% vs 36.2%; P = .001), lower age at transplantation (38 ± 14 vs 46 ± 12 years; P = .004), shorter time on dialysis (33 ± 49 vs 59 ± 157 months; P = .043), and higher rate of living donor grafts (PD 31.6% vs HD 13.1%; P = .003). Donor age (PD 43 ± 13 vs HD 45 ± 14 years; P = .30), human leukocyte antigen mismatch (P = .17), panel reactive antibody values (HD 11 ± 22 vs PD 13 ± 26; P = .55), and hyperimmunized patients (HD 3.73%; PD 7.89%; P = .23) were not different. Primary graft failure (3.4% vs 0%; P = .025) and DGF (37.1% vs 13.1%; P = .037) were more frequent among HD patients, but incidences of acute rejection episodes were similar (HD 10.5% vs PD 5.3%; P = 0.19). Neither recipient survival at 1 (97% in PD and HD) or 3 years (HD 90% vs PD 94%; P = .657) nor allograft survival at 1 year (HD 94% vs PD 95%; P = .80) or 3 years: (HD 70%, vs PD 81%; P = .73) were different. Graft function was similar at 1 (HD 64.2 ± 25 vs PD 56.4 ± 24 mL/min; P = .17) and 3 years (HD 62.3 ± 21 vs PD 46 ± 23 mL/min; P = .16). In our study, HD patients showed an higher incidence of DGF and primary allograft failure, but there was no difference in acute rejection episodes, long-term survivals, or renal function.
