  2. Acute tubular necrosis - Wikipedia

    en.wikipedia.org/wiki/Acute_tubular_necrosis

    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 ]

  3. Hemoglobinuria - Wikipedia

    en.wikipedia.org/wiki/Hemoglobinuria

    Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. [1] The condition is caused by excessive intravascular hemolysis, in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma. [2]

  4. Azotemia - Wikipedia

    en.wikipedia.org/wiki/Azotemia

    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.

    en.wikipedia.org/wiki/Urinary_cast

    Cells can adhere in random order or in sheets and are distinguished by large, round nuclei and a lower amount of cytoplasm. These can be seen in acute tubular necrosis and toxic ingestion, such as from mercury, diethylene glycol, or salicylate. In each case, clumps or sheets of cells may slough off simultaneously, depending on the focality of ...

  7. Coagulative necrosis - Wikipedia

    en.wikipedia.org/wiki/Coagulative_necrosis

    Coagulative necrosis is a type of accidental cell death typically caused by ischemia or infarction. In coagulative necrosis, the architectures of dead tissue are preserved for at least a couple of days. [1] It is believed that the injury denatures structural proteins as well as lysosomal enzymes, thus blocking the proteolysis of the damaged cells.

  8. Hepatorenal syndrome - Wikipedia

    en.wikipedia.org/wiki/Hepatorenal_syndrome

    Acute tubular necrosis (ATN) involves damage to the tubules of the kidney, and can be a complication in individuals with cirrhosis, because of exposure to toxic medications or the development of decreased blood pressure. Because of the damage to the tubules, ATN affected kidneys usually are unable to maximally resorb sodium from the urine.

  9. Pyelonephritis - Wikipedia

    en.wikipedia.org/wiki/Pyelonephritis

    Acute pyelonephritis is an exudative purulent localized inflammation of the renal pelvis (collecting system) and kidney. The kidney parenchyma presents in the interstitium abscesses (suppurative necrosis), consisting in purulent exudate (pus): neutrophils, fibrin, cell debris and central germ colonies (hematoxylinophils). Tubules are damaged by ...
