There are various causes of acute kidney injury (AKI). Previously published textbooks by other authors classify these causes into three categories, partly for the purpose of differentiation (Sesso, Am J Kidney Dis 44:410–419, 2004). This chapter provides a general explanation of the causes of...

AKI was formerly known as acute renal failure. AKI is a complex condition with a wide range of causes, including ischemic injury and exposure to nephrotoxic agents. [1] The widely accepted Kidney Disease: Improving Global Outcome (KDIGO) definition of AKI is based on the change of serum...
Prerenal AKI - Causes are factors that reduce circulation, causing a reduction in renal blood flow - EX: Severe dehydration, heart failure, hypotension, blood loss, hypoxia, sepsis/shock- Autoregulatory mechanisms attempt to preserve blood flow during shock- blood is pulled to other essential orga...
ACUTE KIDNEY INJURY -Acute kidney injury is defined as a rapid loss of kidney fucntion because of Prerenal, Intrarenal, or Postrenal damage to the kidney -Onset is sudden but usually reversible once the cause is adressed PRERENAL (No direct damage to kidney tissue) Prerenal: Causes factors...

There are 3 main causes of AKI: A sudden dramatic drop in blood flow to the kidneys, nephrotoxic drugs, or a sudden blockage. AKI occurs in 3 types: Prerenal – occurs when there is inadequate perfusion of blood to the kidneys. Renal (intrinsic) injury includes diseases affecting the kidn...
