As the renal transplant is the best therapeutic option for the treatment of End-Stage Renal Disease, in the city of Concepción (Chile), a Renal Transplant Program (TX) was started in 1994. The aim was to characterize the kidney graft survival of TX performed in our hospital, through a descriptive, transversal, correlational and comparative study of the results obtained in two periods, A: from 1994 to 2003 and, B: from 2004-2012. Statistical analysis was performed using the SPSSv20.0 software. The function of survival was calculated using the nonparametric Kaplan-Meier test; and to compare the variables we used the log-rank test. From the results, we emphasize that the survival of patients transplanted in the period A was better in the first year (96%), but was lower at 3 (90%), 5 (86%) and 10 years (72 %) compared to the period B in which the first year was 95%, at 3 of 90% at 5 and 10 years of 87%. Graft survival was also higher in the period A than in B, and better when the time of ischemia was less than 24 hours and no differences in relation to sex of the donor and recipient and type of immunosuppressive treatment. Infections were the first cause of death and surgical complications the main cause of graft loss.
