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.
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. [48] This was a 346% increase in hospitalizations from 1997, when there were 98,000 acute kidney injury stays. [49]
Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. [1] In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine.
Although often reliable at discriminating between prerenal azotemia and acute tubular necrosis, the FE Na has been reported to be <1% occasionally with oliguric and nonoliguric acute tubular necrosis, urinary tract obstruction, acute glomerulonephritis, renal allograft rejection, sepsis, and drug-related alterations in renal hemodynamics.

Generally, diseases outlined within the ICD-10 codes N00-N19, N20.0 within Chapter XIV: Diseases of the genitourinary system should be included in this category. Wikimedia Commons has media related to Kidney diseases .
Acute kidney injury (AKI), previously called acute renal failure (ARF), [12] [13] is a rapidly progressive loss of renal function, [14] generally characterized by oliguria (decreased urine production, quantified as less than 400 mL per day in adults, [15] less than 0.5 mL/kg/h in children or less than 1 mL/kg/h in infants); and fluid and ...
The most common causes of high anion gap metabolic acidosis are: ketoacidosis, lactic acidosis, kidney failure, and toxic ingestions. [3] Ketoacidosis can occur as a complication of diabetes mellitus (diabetic ketoacidosis), but can occur due to other disorders, such as chronic alcoholism and malnutrition. In these conditions, excessive free ...
Uremic pericarditis is associated with azotemia, and occurs in about 6-10% of kidney failure patients. BUN is normally >60 mg/dL (normal is 7–20 mg/dL). However, the degree of pericarditis does not correlate with the degree of serum BUN or creatinine elevation. The pathogenesis is poorly understood. [2]
