Acute kidney injury was one of the most expensive conditions seen in U.S. hospitals in 2011, with an aggregated cost of nearly $4.7 billion for approximately 498,000 hospital stays. [49] This was a 346% increase in hospitalizations from 1997, when there were 98,000 acute kidney injury stays. [50]
FE Na can be useful in the evaluation of acute kidney failure in the context of low urine output. Low fractional excretion indicates sodium retention by the kidney, suggesting pathophysiology extrinsic to the urinary system such as volume depletion or decrease in effective circulating volume (e.g. low output heart failure).
Unlike chronic kidney disease, however, the kidneys can often recover from acute kidney injury, allowing the person with AKI to resume a normal life. People with acute kidney injury require supportive treatment until their kidneys recover function, and they often remain at increased risk of developing future kidney failure.
Renal azotemia (acute kidney failure) typically leads to uremia. It is an intrinsic disease of the kidney, generally the result of kidney parenchymal damage. Causes include kidney failure, glomerulonephritis, acute tubular necrosis, or other kidney disease. [3] The BUN:Cr in renal azotemia is less than 15.
Because necrosis is often not present, the term acute tubular injury (ATI) is preferred by pathologists over the older name acute tubular necrosis (ATN). [1] ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI. [2] Common causes of ATN include low blood pressure and use of nephrotoxic drugs. [2]
Chronic kidney disease is defined as prolonged kidney abnormalities (functional and/or structural in nature) that last for more than three months. [1] Acute kidney disease is now termed acute kidney injury and is marked by the sudden reduction in kidney function over seven days.
Acute anuria, where the decline in urine production occurs quickly, is usually a sign of obstruction or acute kidney failure. Acute kidney failure can be caused by factors not related to the kidney, such as heart failure , mercury poisoning , infection, and other conditions that cause the kidney to be deprived of blood flow.
Kidney infarction: CT scan of the abdomen showing partial infarct of the left kidney. Specialty: Nephrology: Symptoms: Abdominal pain, nausea, vomiting, and fever. [1] Complications: Acute kidney injury and chronic kidney disease. [1] Causes: Cardioembolic disease, renal artery injury, and hypercoagulable state. [1] Diagnostic method
