AbstractSepsis is the commonest cause of acute kidney injury in critically ill patients. Its pathophysiology is complex and not well understood. Until recently, it was believed that kidney hypoperfusion is the major contributor of septic acute kidney injury. However, recent publications have improved our understanding on this topic. We now know that its mechanisms included the following: (1) renal macrocirculatory and microcirculatory disturbance, (2) surge of inflammatory markers and oxidative stress, (3) coagulation cascade activation, and (4) bioenergetics adaptive response with controlled cell-cycle arrest aiming to prevent cell death. Uncovering these complicated mechanisms may facilitate the development of more appropriate therapeutic measures in the future.Copyright © 2015 Elsevier Inc. All rights reserved.
