Acute kidney injury. Pathologic kidney specimen showing marked pallor of the cortex, contrasting to the darker areas of surviving medullary tissue. The patient died with acute kidney injury. Acute kidney injury (AKI), previously called acute renal failure (ARF), [ 1 ][ 2 ] is a sudden decrease in kidney function that develops within 7 days, [ 3 ...
Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys. 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 ...
The patient died with acute kidney injury. Kidney disease, or renal disease, technically referred to as nephropathy, is damage to or disease of a kidney. Nephritis is an inflammatory kidney disease and has several types according to the location of the inflammation. Inflammation can be diagnosed by blood tests.
Kidney failure, also known as end-stage renal disease (ESRD), is a medical condition in which the kidneys can no longer adequately filter waste products from the blood, functioning at less than 15% of normal levels. [ 2 ] Kidney failure is classified as either acute kidney failure, which develops rapidly and may resolve; and chronic kidney ...
Interstitial nephritis is uncommon (<1% incidence) in patients without any symptoms but occurs in about 10-15% of hospitalized patients with acute kidney injury of unknown cause. [2] While it can occur in patients of all ages, it is more common in elderly patients, perhaps due to increased exposure to drugs and other triggering causes. [2]
In the United States, both quantities are given in mg/dL The ratio may be used to determine the cause of acute kidney injury or dehydration. The principle behind this ratio is the fact that both urea (BUN) and creatinine are freely filtered by the glomerulus ; however, urea reabsorbed by the renal tubules can be regulated (increased or ...
Hemolytic–uremic syndrome (HUS) is a group of blood disorders characterized by low red blood cells, acute kidney injury (previously called acute renal failure), and low platelets. [1] [3] Initial symptoms typically include bloody diarrhea, fever, vomiting, and weakness. [1] [2] Kidney problems and low platelets then occur as the diarrhea ...
Renal cortical necrosis. Renal cortical necrosis (RCN) is a rare cause of acute kidney failure. The condition is "usually caused by significantly diminished arterial perfusion of the kidneys due to spasms of the feeding arteries, microvascular injury, or disseminated intravascular coagulation " and is the pathological progression of acute ...
