Acute kidney injury (AKI) is one of the most important complications of critical illness and a significant public health concern. AKI is commonly associated with sepsis, cardiac dysfunction, and exposure to nephrotoxic medication; however, less common causes of AKI can lead to devastating patient outcomes when the underlying diagnosis is missed or delayed. These uncommon causes of AKI fall into 3 large categories: structural, immune mediated, and microvascular, including various types of thrombotic microangiopathy. Kidney imaging, urine studies, and serum hemolytic studies should be a routine part of the evaluation of AKI among critically ill patients.
急性肾损伤 (AKI) 是危重病患者最重要的并发症之一,也是一个重大的公共卫生问题。AKI 通常与脓毒症、心功能障碍和接触肾毒性药物有关;然而,当潜在诊断被忽视或延迟时,AKI 的一些不太常见的原因会导致灾难性的患者结局。这些 AKI 的不常见原因可分为 3 大类:结构性、免疫介导性和微血管性,包括各种类型的血栓性微血管病。对于危重病患者的 AKI 评估,肾脏影像学、尿液研究和血清溶血研究应作为常规检查的一部分。
