More Than 1000 Kidney Transplants Performed in Pamplona, Navarra: Data From the Collaborative Transplant Study.

INTRODUCTION: The Kidney Transplant Program started at the Clinica Universidad de Navarra (Pamplona, Spain) in September of 1969. The 1000th kidney transplant was performed in September 2015. Data from kidney transplants have been included in the Collaborative Transplant Study since 1983. MATERIALS AND METHODS: Data on patient and graft survival of the 635 kidney transplants (557 first kidney transplants and 78 second kidney transplants) performed in the Clinica Universidad de Navarra between 1990 and 2014, as well as the estimated average life of the grafts are described and compared with data from the more than 150,000 European kidney transplants included in the Collaborative Transplant Study in the same period. RESULTS: Data of our patient and graft survival are statistically significantly better (P < .05) than those of the over 150,000 European transplants analyzed in the Collaborative Transplant Study in the same period. The estimated half-life of the kidney transplants performed in our Center is 18.5 years for first transplants and 15.7 years for second transplants, compared to 13.9 and 11.2 years, respectively, calculated for the European transplants. CONCLUSIONS: Data obtained from the Collaborative Transplant Study confirm excellent graft survival in our Center with an estimated half-life higher than that of the European transplants included in this study.

Short-Term Outcomes of 100 Consecutive Kidney Transplantations in a 3-Year Period: A Single-Center Experience.

BACKGROUND: The results of kidney transplantation have improved significantly in the last decade with patient and graft survival rates that range from 92% to 95%. METHODS: We analyzed the clinical results in the last 100 consecutive patients with a follow-up of 6-42 months at our institution. We also made a general evaluation of the patients before surgery as candidates for transplantation and divided them into 3 groups (good, moderate, and poor). RESULTS: We had 8 living donors and 92 cadaveric kidney transplantation cases. Principal cause of donor death was cerebrovascular disease accounting for 64%. Mean age of recipients was 55.1 ± 12.9 years with a total of 65 males. Currently there are 96 functioning allografts. During this 3-year period, 2 patients suffered graft loss and 2 patients died with a functioning allograft. We studied whether there were statistically significant differences in renal function (Modification of Diet in Renal Disease Study Equation [MDRD]) at 12 months and at last visit with respect to the evaluation of recipient as candidate for renal transplantation. CONCLUSION: Our observations suggest great improvement of early results of renal transplantation in recent years, including complex cases. In this 3-year period we had a patient survival rate of 98% and a graft survival rate of 96% of cases. Further dedicated prospective studies that aim to evaluate or to propose possible recipient-related predictors for kidney transplantation outcomes in different populations are needed.
