Acute kidney injury (AKI) is a sudden loss of kidney function, ranging from a few hours to several days. Patients may be asymptomatic or produce little to no urine; in severe cases, they may exhibit symptoms affecting various organ systems.
AKI may be diagnosed based on blood work, as it is marked by increased creatinine levels. To prevent irreversible kidney damage, AKI must be diagnosed and treated early. Treatment of AKI aims to ensure that the kidneys can filter the blood adequately and prevent further kidney damage and complications.
