Outcome of patients with hemodialysis or peritoneal dialysis undergoing simultaneous pancreas-kidney transplantation....

Controversy remains with regard to the higher risk of intra-abdominal infections and lower patient and graft survival when peritoneal dialysis (PD) rather than hemodialysis (HD) is used in simultaneous pancreas-kidney transplantation (SPKT).

From March 1995 to December 2015, we performed 165 SPKTs. Prior to transplant, patients received hemodialysis (group HD; n = 98) or peritoneal dialysis (group PD; n = 67). A comparison was made to analyze post-transplant complications and patient, pancreas, and kidney graft survivals.

Donor, pretransplant, and perioperative recipient variables were similar in both groups. Overall rates of infections (69.4% in HD vs 73.1% in PD; P = .50) and intra-abdominal infections (31.6% in HD vs 35.8 in PD; P = .57) were similar in both groups. The rates of pancreatitis, hemorrhage or thrombosis of the graft, duodenal graft leak, relaparotomy, transplantectomy, pancreas rejection, and retransplantation were similar in both groups. Patient survival at 1, 3, and 5 years (95.9%, 93.9%, and 93.9% in HD vs 95.5%, 92.2%, and 90.4% in PD; P = .54) and pancreas graft survival (83.6%, 78.0%, and 71.8% in HD vs 79.2%, 77.4%, and 71.0% in PD; P = .8) were similar in both groups. Kidney graft survival was similar in both groups. Pancreas graft thrombosis, rejection, and relaparotomy for intra-abdominal complications were independent predictors of lower pancreas graft survival, but dialysis modality did not influence patient or graft survival.

Pre-SPKT modality of dialysis does not significantly influence overall or intra-abdominal infection and patient, pancreas, or kidney graft survivals.
