Acute Kidney Injury (AKI)

Acute Kidney Injury (AKI)

by Amy Sussman, MD

Acute kidney injury (AKI) is defined (as the name suggests) by an acute and usually reversible reduction in glomerular filtration rate (GFR), a measure of kidney function. Often a decline in urine output may be the only sign of AKI, as often, a patient’s blood urea nitrogen level may not be elevated immediately after the renal insult. AKI can result in accumulation of electrolytes like sodium and potassium as well as water and other metabolic products, the sequelae of which can be deadly.

AKI is very common, and you will without a doubt see it regularly if you work with hospitalized patients. It can be seen in a large percentage of hospital and ICU admissions. There is no clear standard drop in GFR that defines an AKI, though several groups have proposed guidelines that have been used in previous studies.

Early recognition of AKI is critical, as the treatment is often aimed at correcting the underlying cause, whether it is prerenal (such as dehydration), intrarenal (such as a medication toxicity), or postrenal (such as severe prostatic hyperplasia obstructing outflow). It is crucial to use clinical judgment to determine the etiology, as administering incorrect treatment may result in significant complications.
