Despite good long-term outcomes of kidney transplants from controlled donation after circulatory death (DCD) donors, there are few uncontrolled DCD (uDCD) programs. This longitudinal study compares outcomes for all uDCD (N = 774) and all donation after brain death (DBD) (N = 613) kidney transplants performed from 1996 to 2015 at our center. DBD transplants were divided into those from standard-criteria (SCD) (N = 366) and expanded-criteria (N = 247) brain-dead donors (ECD). One-, 5-, and 10-year graft survival rates were 91.7%, 85.7%, and 80.6% for SCD; 86.0%, 75.8%, and 61.4% for ECD; and 85.1%, 78.1%, and 72.2% for uDCD, respectively. Graft survival was worse in recipients of uDCD kidneys than of SCD (P = .004) but better than in transplants from ECD (P = .021). The main cause of graft loss in the uDCD transplants was primary nonfunction. Through logistic regression, donor death due to pulmonary embolism (OR 4.31, 95% CI 1.65-11.23), extrahospital CPR time ≥75 minutes (OR1.94, 95%CI 1.18-3.22), and in-hospital CPR time ≥50 minutes (OR 1.79, 95% CI 1.09-2.93) emerged as predictive factors of primary nonunction. According to the outcomes of our long-standing kidney transplantation program, uDCD could help expand the kidney donor pool.
尽管来自控制性循环死亡(DCD)供体的肾移植具有良好的长期结果,但无控制的 DCD(uDCD)计划很少。本纵向研究比较了我们中心 1996 年至 2015 年间进行的所有 uDCD(N=774)和所有脑死亡后供体(DBD)(N=613)肾移植的结果。DBD 移植分为标准标准(SCD)(N=366)和扩展标准(ECD)(N=247)脑死亡供体。SCD 的 1、5 和 10 年移植物存活率分别为 91.7%、85.7%和 80.6%;ECD 分别为 86.0%、75.8%和 61.4%;uDCD 分别为 85.1%、78.1%和 72.2%。uDCD 肾移植受者的移植物存活率较 SCD 差(P=0.004),但优于 ECD 移植(P=0.021)。uDCD 移植中移植物丢失的主要原因是原发性无功能。通过逻辑回归,由于肺栓塞导致供体死亡(OR 4.31,95%CI 1.65-11.23),院外心肺复苏(CPR)时间≥75 分钟(OR 1.94,95%CI 1.18-3.22),院内 CPR 时间≥50 分钟(OR 1.79,95%CI 1.09-2.93)是原发性无功能的预测因素。根据我们长期肾移植项目的结果,uDCD 可以帮助扩大肾脏供体库。
