BACKGROUND: The aim of our cohort study was to assess survival of the patients after kidney graft failure. METHODS: Patients starting dialysis after graft failure between January 1, 2004 and December 31, 2010 were identified from the Slovenian Renal Replacement Therapy (RRT) Registry and followed to December 31, 2011. The control group consisted of 351 incident dialysis patients, who were kidney transplant candidates. Survival data were not censored for retransplantations. RESULTS: After a median of 7.4 (interquartile range [IQR]) 0.4-13.0) years with a functioning graft and a median of 15.5 (IQR 7.8-20.7) years on RRT 82 patients started dialysis. Their mean (± standard deviation [SD]) age was 50.4 ± 12.7 years vs 49.2 ± 13.9 years for the incidental transplantation candidates (P = .49). There were sixty-one percent men (vs 64%; P = .67), and all subjects were on hemodialysis treatments. By Dec 31, 2011, 19 (23%) patients had undergone retransplantation and 27 (33%) died after a median of 1.6 (IQR 0.2-5.4) months on dialysis. The causes of death were infection (n = 15), cardio-disease-vascular (n = 6), malignancy (n = 4), or cerebrovascular (n = 2). Deceased patients were significantly older: 60.0 ± 7.9 vs 45.7 ± 12.0 years (P < .001) and more often men: (78% vs 53% P = .05). The unadjusted overall 1- and 3-year survivals rates after graft failure of 70% and 68% were significantly lower than those in the control candidate group of (98% and 93%, respectively (log-rank; P < .001). This difference remained significant upon multivariate analysis (hazard ratio [HR], 12.0; P < .001). The subgroup of 53 patients who started dialysis after chronic graft failure showed unadjusted 1- and 3-year survival rates of 82% and 80%, respectively which were still worse than the control group (P = .001), a difference that remained significant upon multivariate analysis (HR, 1.75; P < .001). CONCLUSION: After kidney graft failure patients experienced increased mortality in the first year after restarting dialysis. However, subjects who survived the first year showed good survival thereafter.
