Description: Acute Kidney Injury (AKI) is defined as a sudden episode of kidney failure or damage that occurs within a few hours or days. This disorder is characterized by an increase in blood creatinine levels and a decrease in urine output. AKI can be caused by various factors, including dehydration, infections, obstructions in the urinary tract, or side effects of medications. It is a significant health issue that can affect individuals of all ages, although it is more common in hospitalized patients, especially those in intensive care units. Early identification and appropriate treatment are crucial to prevent long-term complications, such as progression to chronic kidney disease. AKI can be classified into three categories: prerenal, renal, and postrenal, depending on the underlying cause of kidney damage. Clinical evaluation includes the patient’s medical history, physical examinations, and laboratory tests to determine kidney function. AKI not only affects the patient’s physical health but can also have a significant emotional and psychological impact, as it may require intensive and prolonged treatments.
