Understanding Acute Kidney Injury (AKI)
Acute kidney injury (AKI) is defined as a sudden decrease in kidney function, often indicated by a rise in serum creatinine or a decline in urine output. Clinically, it is categorized into three main types: prerenal, intrarenal, and postrenal. Prerenal causes are typically due to insufficient blood flow to the kidneys, which can result from factors like dehydration, shock, or heart failure. Recognizing that a majority of AKI cases are either prerenal or postrenal highlights the importance of prompt fluid resuscitation and monitoring, which can often resolve the issue.
