[摘要]：Background. Use of kidneys from donors aged 75 years and older is controversial. The purpose of this study was to evaluate the outcome of kidney transplantation (KT) involving these expanded criteria donors. Materials and Methods. From January 2001 to November 2009, 52 patients were transplanted with grafts from deceased donors aged 75 years and older. Donor and recipient data and intra- and postoperative variables were analyzed by univariate and multivariate regression analyses. Graft and patient survival were calculated using the Kaplan-Meier method. Results. Forty-one single and 11 double KTs were performed. Median recipient age was 66 years. After a median follow-up of 30 months, 37 of 52 patients are alive, 30 with functioning grafts (81%). Graft and patient survival rates at 3 and 5 years are 63% and 53%, and 78% and 64%, respectively. Double KT was significant predictor for graft survival by multivariate analysis. Five-year graft survival for single and double KT was 41% and 90%, respectively (P=0.0394). Comorbidity Index, hospital stay, acute rejection reaction, re-KT, and induction immunosuppressive therapy with interleukin-2 were significant predictors for patient survival by univariate analysis. Hospital stay and induction immunosuppression therapy reached multivariate significance. Double KT, cold ischemia time, and Comorbidity Index were found potential predictors of delayed graft function in our series. Conclusions. Fairly good long-term outcome of KT from donors aged 75 years and older can be achieved in elderly recipients with low comorbidities when dual kidney grafting is used and when re-transplantations and high grade surgical complications are avoided.
