Chapter 9 Urinary System- Pathology Flashcards
Branch of medicine involved in diagnosis and treatment of diseases and disorders of urinary system. Urologist
Urology
Complete suppression of urine formed by kidneys and a complete lack of urine excretion
Anuria
Accumulation of nitrogenous waste in bloodstream. Occurs when kidney fails to filter these wastes from blood
Azotemia
Presence of bacteria in the urine
Bacteriuria
Stone formed within an organ by an accumulation of mineral salts. Caculi
Calculus
Urinary bladder pain
Cystalgia
Bladder stone
Cystolith
Profuse bleeding from urinary bladder
Cystorrhagia
Increased formation and exertion of urine
Diuresis
Difficult of painful urination
Dysuria
Involuntary discharge of urine after the age by which bladder control should have been established. Usually occurs at the age of 5. Nocturnal enuresis refers to bed-wetting at night
Enuresis
Greater than normal occurrence in the urge to urinate, w/o an increase in the total daily volume of urine.
Frequency
Presence of sugar in urine
Glycosuria
Presence of blood in urine
Hematuria
Decrease in the force of urine in stream, often with difficulty initiating the flow. Often a symptom of a blockage along urethra, such as an enlarged prostate gland
Hesitancy
Presence of ketones in urine. Occurs when body burns fat instead of glucose for energy, such as uncontrolled diabetes mellitus
Ketonuria
Kidney stone
Nephrolith
Kidney is enlarged
Nephromegaly
Kidney is abnormally soft
Nephromalacia
Kidney tissue has become hardened
Nephrosclerosis
Having to urinate frequently during the night
Nocturia
Producing too little urine
Oliguria
Producing an unusually large volume of urine
Polyuria
Presence of urine in urine
Proteinuria
Presence of pus in urine
Pyuria
Pain caused by kidney stone.
Renal colic
Narrowing of a passageway in the urinary system
Stricture
Accumulation of waste products in bloodstream. Associated with renal failure
Uremia
Ureter is stretched out or dilated
Ureterectasis
Stone in ureter
Ureterlith
Ureter has become narrow
Ureterostenosis
Urethral pain
Urethralgia
Profuse bleeding from urethra
Urethrorrhagia
Urethra has become narrow
Urethrostenosis
Feeling to urinate immediately
Urgency
Involuntary release of urine.
Urinary incontinence
Inability to fully empty the bladder, often indicates a blockage in the urethra
Urinary retention
Damage to renal tubules due to presence of toxins in urine of to ischemia. Results in oliguria
Acute tubular necrosis (ATN)
Accumulation of damage to the glomerulus capillaries due to chronic high blood sugars of diabetes mellitus
Diabetic nephropathy
Inflammation of kidney (primarily of glomerulus). Results in proteinuria and hematuria
Glomerulonephritis
Distention of renal pelvis due to urine collecting in kidney; often a result of obstruction of a ureter
Hydronephrosis
Kidney inflammation
Nephritis
Presence of calculi in kidney.
Nephrolithiasis
Kidney tumor
Nephroma
General term describing presence of kidney disease
Nephropathy
Downward placement of kidney out of its normal location; commonly called floating kidney
Neophroptosis
Damage to glomerulus resulting in protein appearing in urine, proteinuria, and corresponding decrease in protein in the bloodstream. Nephrosis
Nephrotic syndrome (NS)
Formation of multiple cysts within kidney tissue.
Polycystic kidneys
Renal pelvis inflammation
Pyelonephritis
Cancerous tumor that arises from kidney tubule cells
Renal cell carcinoma
Inflammation of renal pelvis and the kidney. One of most common kidney disease. May be result of urinary tract infection that moved up to kidney by way of ureters.
Pyelonephritis
Inability of kidneys to filter wastes from blood resulting in uremia.
Renal failure
Malignant kidney found most often in children
Wilm’s tumor (VILMZ)
Cancerous tumor that arises from the cells lining the bladder; major sign of hematuria
Bladder cancer
Blockage of the bladder outlet. Often caused by enlarged prostate gland in males
Bladder neck obstruction (BNO)
Urinary bladder inflammation
Cystitis
Hernia or protrusion of urinary bladder into the wall of vagina
Cystocele
Disease of unknown cause in which there is inflammation and irritation of the bladder. Most commonly seen in middle-aged women
Interstitial cystitis
Loss if nervous control that leads up to retention; may be caused by spinal cord injury or multiple sclerosis
Neurogenic bladder
Infection, usually from bacteria, of any organ of urinary system. Most often begins with cystitis and may ascend into ureters and kidneys. Most common in women
Urinary tract infection (UTI)
