Q

Fluid overload syndrome

A

Occurs when there is excessive sodium and water retention in the body that cannot be adequately removed by diseased kidneys. Symptoms and signs of vascular congestion may include fatigue, shortness of breath, hypertension, congestive heart failure, ascites, pleural effusions and peripheral edema

Q

Glomerulonephritis

A

Kidney disease in which the glomerular tuft (Bowman’s capsule) becomes inflamed. The glomerular membranes become extremely porous, allowing both protein and blood cells to flow freely into the nephron tubules. Occasionally, episodes of acute glomerulonephritis permanently destroy nephron capsules. Repeated small bouts may destroy more and more nephrons, causing chronic glomerulonephritis.

Q

Hemodialyzer

A

An apparatus that forces the affected individual’s blood through semipermeable tubes immersed in fluid. Urea and other metabolic byproducts diffuse from the blood into the surrounding fluids; performing limited kidney function. Blood must be anticoagulated during dialysis

Q

Hunner’s ulcers

A

A lesion involving all layers of the bladder wall, seen in chronic interstitial cystitis

25
Q

Hydronephrosis

A

A disorder of the kidneys in which the ureter becomes obstructed (kidney stone, inflammation, fibrosis, etc.) causing the kidney to become distended by the accumulated urine. Prolonged distention can cause atrophy of nephrons, with residual reduction or loss of kidney function.

26
Q

Immunosuppressive agents

A

Agents that block the body’s effort to reject foreign bodies or tissues; used especially in organ transplantations

27
Q

Isograft

A

Tissue or organ transplanted between genetically identical individuals, also known as syngraft

28
Q

Kidney

A

Either of the two organs in the lumbar region that filter the blood of toxic metabolic byproducts excreted as urine; also regulates the concentration of electrolytes (hydrogen, sodium, phosphorus, potassium, etc.) in the blood

29
Q

Kidney failure

A

Severe renal insufficiency, generally accompanied by signs and symptoms of uremia.

30
Q

Lithotripsy

A

A treatment for kidney stones in which acoustic shock waves are used to disintegrate renal calculi

31
Q

Nephrectomy

A

Surgical removal of a kidney

32
Q

Nephritis

A

Inflammation of the kidney; may be localized or diffuse and may involve the glomeruli, tubules, or the interstitial kidney tissues

33
Q

Nephrolithiasis

A

A condition marked by the presence of renal calculi ( kidney stones)

34
Q

Nephron

A

The functioning filtering unit of the kidney, consisting of the glomerulus (Bowman’s capsule) and uriniferous tubule. The two kidneys contain approximately two million nephrons and approximately 3/4 of these nephrons can be destroyed before blood composition becomes excessively abnormal.

35
Q

Nephrosclerosis

A

Sclerosis (hardening) of the vascular arteries, arterioles and sometimes, the capillaries of the kidney; the form of “end-organ” damage due to hypertension.

36
Q

Nephrosis

A

A generic term for any disease of the kidney characterized by degenerative lesions of the renal tubules and/or glomeruli; generally used synonymously with the term, “nephrotic syndrome”.

37
Q

Nephrotic syndrome

A

A generalized name of a group of diseases involving defective kidney glomeruli, characterized by proteinuria, hypoalbuminemia, hyperlipidemia, and varying degrees of edema

A condition of chronic renal disease characterized by edema, proteinuria, hypoalbuminemia, hyperlipidema

38
Q

Nocturia

A

Excessive frequency of urination at night

39
Q

Pathologic fractures

A

Fractures resulting from sealing of the bone structure by pathologic processes such as osteomalacia and osteoporosis

40
Q

Peritoneal dialysis

A

The removal of toxic metabolic byproducts from the blood by diffusion (via a dialyzing solution) which takes place inside the abdominal cavity. The dialyzing solution is infused into, and removed from, the abdominal cavity on either a continuous or an intermittent basis

41
Q

Polycystic kidney disease

A

A hereditary, congenital condition characterized by multiple cysts of both kidneys

42
Q

Polydipsia

A

The presence of excess protein in the urine

45
Q

Pyuria

A

The presence of pus in the urine

46
Q

Rejection crisis

A

Severe immune reaction of the body against grafted tissues, in which the body’s defense mechanisms (antibodies, white blood cells, platelets, fibrin, etc.,) attack the foreign tissue and cause failure of the graft; usually accompanied by pain and swelling

47
Q

Renal calculus (kidney stones)

A

A solidified deposit developing in the kidney, usually composed of mineral salts (calcium, oxalates, uric acid, ammonium magnesium, phosphates, cholesterol) And occurring in a variety of sizes and shapes; may be single or multiple

48
Q

Renal

A

Pertaining to the kidney

49
Q

Renal insufficiency

A

Abnormal (decreased) kidney function, ranging from mild to severe

50
Q

Serum albumin

A

A major plasma protein that is responsible for much of the plasma colloidal osmotic pressure of the blood and serves as a transport protein

51
Q

Stricture (ureteral, urethral)

A

Abnormal narrowing (of the urethra or the ureter) due to fibrosis or the deposit of abnormal tissue

52
Q

Urea

A

The chief nitrogenous constituent of urine and the chief nitrogenous end product of the metabolism of proteins. It is a major route for removal of the ammonia produced in the metabolism of amino acids in the liver and kidney

53
Q

Uremia

A

The retention in the blood of excessive byproducts of protein metabolism and of potassium, which produce a toxic condition marked by nausea, vomiting, headache, vertigo, dimness of vision, coma or convulsions, and a fetid odor of breath; results of nephron failure to adequately excrete urea and other protein byproducts

54
Q

Ureter

A

The bilateral membranous canals conducting urine from the kidneys to the bladder

55
Q

Urethra

A

The membranous canal conducting urine from the bladder outside the body

56
Q

Uria

A

A suffix denoting a characteristic or constituent of the urine

57
Q

Urinary tract

A

Those organs and ducts that participate in the secretion and elimination of urine; I.e., the kidneys, ureters, bladder, and urethra

58
Q

Urine

A

The fluid excreted by the kidneys, stored in the bladder, and discharged by the urethra. Healthy urine is 96% water and 4% solutes

59
Q

Urine total-protein-to-creatinine ratio

A

A laboratory calculation based on total protein and creatinine in a urine sample.
