Acute kidney injury is defined as acute kidney damage due to injury. This AKI is divided into three broad terms including: pre-renal, renal or post renal. Pre-renal is any cause that is before kidney (such as shock, or bleeding). Renal type of damage includes any cause with in the kidney that can lead to damage such as vasculitis, sepsis or myeloma). Post renal kidney injury is due to any disease of urinary tract such as renal or urinary stones, tumors, strictures or inflammation. AKI management includes treating the cause for example treating dehydration or removing obstruction.
The causes of acute kidney injury can be divided into three categories prerenal (caused by decreased renal perfusion, often because of volume depletion), intrinsic renal (caused by a process within the kidneys), and postrenal (caused by inadequate drainage of urine distal to the kidneys)
