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 ]
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 tubular necrosis. [1]
Acute tubular necrosis due to ischemia is often preceded by prerenal acute kidney injury, since prerenal AKI results in less blood sent to the kidneys. All that secretion and reabsorption in the tubules takes a lot of energy, and so these cells are particularly sensitive to a loss of blood supply, especially the cells in the proximal tubule and ...
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.
Inborn errors of renal tubular transport are metabolic disorders which lead to impairment in the ability of solutes, such as salts or amino acids, to be transported across the brush border of the renal tubule. This results in disruptions of renal reabsorption. [citation needed]

Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, [1] but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, [2] in which sense it is distinguished from nephritis, which involves inflammation.
Fanconi syndrome or Fanconi's syndrome (English: / f ɑː n ˈ k oʊ n i /, / f æ n-/) is a syndrome of inadequate reabsorption in the proximal renal tubules [1] of the kidney.The syndrome can be caused by various underlying congenital or acquired diseases, by toxicity (for example, from toxic heavy metals), or by adverse drug reactions.
