Kidney transplantation is the best treatment for end-stage renal disease. However, due to organ shortage, suboptimal grafts are increasingly being used.
We carried out a review on the methods and techniques of organ optimization in the cadaveric setting. Donor care is the first link in a chain of care. Right after brain death, there is a set of changes, of which hormonal and hemodynamic changes are the most relevant. Several studies have been conducted to determine which drugs to administer, although in most cases, the results are not definitive. The main goal seems rather achieve a set of biochemical and hemodynamic objectives. The ischemia-reperfusion injury is a critical factor for kidney damage in transplantation. One of the ways found to deal with this type of injury is preconditioning. Local and remote ischemic preconditioning has been studied for various organs, but studies on the kidney are scarce. A new promising area is pharmacological preconditioning, which is taking its first steps. Main surgical techniques were established in the late twentieth century. Some minor new features have been introduced to deal with anatomical variations or the emergence of donation after circulatory death. Finally, after harvesting, it is necessary to ensure the best conditions for the kidneys until the time of transplantation. Much has evolved since static cold preservation, but the best preservation conditions are yet to be determined. Conservation in the cold has come to be questioned, and great results have appeared at temperatures closer to physiological.
肾移植是治疗终末期肾病的最佳方法。然而,由于器官短缺,越来越多的次优移植物被使用。
我们对尸体器官优化的方法和技术进行了综述。供体护理是护理链的第一环节。在脑死亡后,会发生一系列变化,其中激素和血液动力学变化最为相关。已经进行了一些研究来确定使用哪些药物,但在大多数情况下,结果并不明确。主要目标似乎是实现一系列生化和血液动力学目标。缺血再灌注损伤是移植中肾脏损伤的一个关键因素。已经发现了一种处理这种损伤的方法是预处理。局部和远程缺血预处理已经在各种器官上进行了研究,但对肾脏的研究很少。一个新的有前途的领域是药理学预处理,它正在迈出第一步。主要的手术技术是在 20 世纪后期确立的。一些较小的新特征被引入,以处理解剖变异或出现循环死亡后捐献。最后,在收获后,有必要确保在移植前为肾脏提供最佳条件。自静态低温保存以来,已经发生了很大的变化,但仍需确定最佳的保存条件。低温保存受到质疑,更接近生理温度的保存效果更好。
