[Survival analysis after kidney transplantation in 1,180 cadaveric graftings].
OBJECTIVE
To analyze the outcome of twenty-two years of cadaveric kidney transplantation and the predict factors impacting on graft survival.


METHODS
The data of 1,180 cadaveric kidney graftings in 1,039 patients between October of 1977 and June of 1999 were summarized by calculation of patient and graft survival rates using Kaplan-Meier product limit estimates. 13 factors that may influence on graft survival were analyzed by the log-rank and Cox model.


RESULTS
The total of 1-, 5-, 10-, 15-, and 20-year patient survival rates were 93.02%, 80.25%, 67.86%, 65.34% and 65.34%, and the corresponding graft survival rates 88.6%, 68.3%, 43.8%, 43.8%, and 32.8%, respectively. Graft half-life was (13.98 +/- 0.96) years. The longest survivor was 22 years after cadaveric kidney transplantation. The quality of life after grafting in 835 alive patients was improved apparently; 95% of them had a normal graft function and 85% returned to work. The result of multivariable analysis using Cox model showed that 8 factors of patient's age, grafting time, pretransplant blood transfusion, cold ischemia time, delayed graft function, time of normal graft function, immunosuppressive regimen, and acute rejection were very important to affect the graft survival.


CONCLUSIONS
Cadaveric kidney transplantation is a successful and effective method to rescue the patients with end-stage renal disease.
