Excessive urination at night.
Term
Dysuria
Definition
Painful or difficult urination.
Term
Hematuria
Definition
The presence of blood in the urine.
Term
Proteinuria
Definition
The presence of excessive amounts of protein in the urine.
Term
Pyuria
Definition
Abnormal numbers of white blood cells in the urine.
Term
BUN
Definition
Blood Urea Nitrogen. Normal level b/w 8-18. High level of BUN or serum nitrogen also called azotemia.
Term
Creatinine

Term
Renal Calculus
Definition
A concretion in the kidney.
Term
Incontinence

Loss of normal control of the bowel or bladder.
Term
Polyuria
Definition
Excessive passage of urine, as in diabetes.
Term
Urinalysis
Definition
Diagnostic physical, chemical, and microscopic examination of a urine sample

Nephrotic Syndrome
Definition
Nephrotic syndrome is a collection of symptoms which occur because the tiny blood vessels (the glomeruli) in the kidney become leaky. This allows protein (normally never passed out in the urine) to leave the body in large amounts. Clinical findings include heavy proteinuria, hypoalbuminemia, and generalized edema.
Term
Nephritic Syndrome
Definition
A syndrome comprising the clinical symptoms of nephritis, hematuria, hypertension, and renal failure
Term
Reflux
Definition
The reverse flow of a liquid.
Term
GFR
Definition
Glomerular Filtration Rate
Term

Definition
Term
Glomerulus
Definition
Term
Pyelonephritis
Definition
Term
Oliguria
Definition
A decrease in the amount of urine secreted.
Term
Prostatic hypertrophy

Enlargement or overgrowth of the prostate gland as a result of an increase in the number of its constituent cells.
Term
Non-oliguria

Anuria
Definition
Inability to form or excrete urine.
Term
Pre-renal
Definition
Syndromes that cause underperfusion to the kidney. Causes include fluid depletion (hemorrhage, dehydration, GI fluid loss), cardiomyopathy (decreased CO), cirrhosis, renal artery atherosclerosis/stenosis, fibromuscular dysplasia, acute transplant rejection, and vasoconstriction of renal microvasculature caused by drugs.
Term
Intrinsic renal damage
Definition
Damage within the kidney. May occur in the glomerulus, interstitial areas, or tubiles. May also be caused by renal calculus or cyst(s)
Term
Post-renal
Definition
Obstruction after the kidneys. Both kidneys must be impaired to see azotemia. Prostatic enlargement is the most commone cause.
Term
Acute tubular necrosis
Definition
Term
Uremic Syndrome
Definition
Term

Definition
Costovertebral Angle Tenderness. Often associated with renal disease.
