In Poland, 95% of organs for transplantation come from donation after brain death (DBD). In 2010, Poland officially joined the European countries in which donation after circulatory death is accepted by law. Currently, the Pomeranian Medical University Transplant Center is the only active location for uncontrolled donation after circulatory death (uDCD) in Poland. To estimate the results of uDCD kidney transplantation with a classical approach to organ recovery, we analyzed data from an early phase of uDCD program.
Prospective observation of uDCD kidney allografts (group 1; n = 8) compared with DBD kidney allografts (group 2; n = 30). The organ recovery protocol was set up on rapid abdominal access without regional perfusion before procurement.
The organs recovered from uDCD during a 24-month period increased the volume of kidneys transplanted at the center by 9.2%. Delayed graft function was diagnosed in 100% vs 46% of allografts (P = .03), respectively. Nevertheless, early posttransplant follow-up did not reveal any graft loss or recipient death cases in the DCD group. After 12 months of follow-up, the mean glomerular filtration rate was 44.5 vs 57.9 mL/min (P < .02), respectively. Crucial factors for acceptable results of uDCD are strict pretransplant assessment of recovered organs and efficient coordination of the transplant team.
Conservative recovery protocol in uDCD under strict prerequisites is feasible to consider in the organ procurement pathway. Preliminary results provide space for an increase in the organ donor pool.
在波兰,95%的移植器官来自脑死亡后捐赠(DBD)。2010年,波兰正式加入了法律认可循环死亡后捐赠的欧洲国家行列。目前,波美拉尼亚医科大学移植中心是波兰唯一开展非控制性循环死亡后捐赠(uDCD)的活跃机构。为了评估采用经典器官获取方法进行uDCD肾移植的效果,我们分析了uDCD项目早期阶段的数据。
对uDCD肾同种异体移植(第1组;n = 8)与DBD肾同种异体移植(第2组;n = 30)进行前瞻性观察。器官获取方案设定为在获取前通过快速腹部入路且不进行区域灌注。
在24个月期间从uDCD获取的器官使该中心移植肾的数量增加了9.2%。移植肾功能延迟分别在100%和46%的同种异体移植中被诊断出来(P = 0.03)。然而,移植后早期随访未发现DCD组有任何移植肾丢失或受者死亡病例。随访12个月后,平均肾小球滤过率分别为44.5和57.9 mL/分钟(P < 0.02)。uDCD取得可接受结果的关键因素是对获取器官进行严格的移植前评估以及移植团队的高效协作。
在严格的前提条件下,uDCD采用保守的获取方案在器官获取途径中是可行的。初步结果为扩大器官供体库提供了空间。
