Acute Kidney Failure
A sudden reduction or loss of kidney function is called acute kidney (renal) failure or acute kidney injury (AKI).The volume of urine decreases in the majority of patients with AKI. Important causes of AKI include intractable diarrhea, intractable vomiting, falciparum malaria, intractable hypotension, sepsis, certain medications (NSAIDs) etc. With proper medical treatment kidney function may be restored in most cases.
