The severity of chronic kidney disease (CKD) is described by six stages; the most severe three are defined by the MDRD-eGFR value, and first three also depend on whether there is other evidence of kidney disease (e.g., proteinuria): 0) Normal kidney function – GFR above 90 (mL/min)/(1.73 m 2) and no proteinuria
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 ...
Renal physiology. This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of ...
Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [ 4 ] Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram).
Renal replacement therapy (RRT) is therapy that replaces the normal blood -filtering function of the kidneys. It is used when the kidneys are not working well, which is called kidney failure and includes acute kidney injury and chronic kidney disease. Renal replacement therapy includes dialysis (hemodialysis or peritoneal dialysis ...
Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function occurs over a period of months to years, or abnormal kidney structure (with normal function). [ 2 ][ 5 ] Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting ...
7203. Anatomical terminology. [ edit on Wikidata] In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [ 1 ] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [ 2 ][ 3 ] They are located on the left and right in the retroperitoneal space, and in adult humans ...
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] as ...
