Chapter 11 Flashcards
filtrate
fluid that passes from the blood through the capillary walls of the glomeruli into Bowman capsule
Electrolyte
Mineral salt that carries an electrical charge when in solution
Nitrogenous waste
Product of protein metabolism that include urea, uric acid, creatine, creatinine, and ammonia
Peristaltic wave
Sequence of rhythmic contraction of smooth muscles of a hollow organ to force material forward and prevent backflow
peritoneum
serous membrane that lines the abdominopelvic cavity and covers most of the organs within the cavity

anuria
Absence of urine production or output
bladder neck obstruction
blockage at the base of the bladder that reduces or prevents urine from passing into the urethra
cystocele
Prolapsing or downward displacement of the bladder due to weakening of the supporting tissues between a woman’s bladder and vagina
dysuria
Painful or difficult urination
end-stage renal disease (ESRD)
Any type of kidney disease in which there is little or no remaining kidney function, requiring the patient to undergo dialysis or kidney transplant for survival
enuresis
Involuntary discharge of urine
fistula
abnormal passage from a hollow organ to the surface or from one organ to another
hydronephrosis
Abnormal dilation of the renal pelvis and the calyces of one or both kidneys due to pressure from accumulated urine that cannot flow past an obstruction in the urinary tract
interstitial cystitis (IC)
Chronic inflammation of the bladder wall that is caused by bacterial infection and is not responsive to conventional antibiotic therapy
nephrotic syndrome
Loss of large amounts of plasma protein,usually albumin, through urnine due to an increased permeability of the glomerular membrane
Neurogenic bladder
Impairment of bladder control due to brain or nerve conduction
polycystic kidney disease (PKD)
Inherited disease in which sacs of fluid called cysts develop in the kidneys
Urgency
sensation of the need to void immediately
Vesicoureteral reflux (VUR)
Disorder caused by the failure of urine to pass through the ureters to the bladder, usually due to impairment of the valve between the ureter and bladder or obstruction in the ureter
Wilms tumor
Rapidly developing malignant neoplasm of the kidney that usually occurs in children
dialysis
Mechanical filtering process used to cleanse the blood of toxic substances, such as nitrogenous wastes, when kidneys fail to function properly
hemodialysis
Type of dialysis in which an artificial kidney machine receives waste-filled blood, filters the blood, and returns the dialyzed blood to the patients bloodstream
peritoneal dialysis
Type of dialysis in which toxic substances are removed from the body by using the peritoneal membrane as the filter by perfusing (flushing) the peritoneal cavity with a warm, sterile chemical solution
kidney transplant
Replacement of a diseased kidney with one that is supplied by a compatible donor
nephropexy
fixation of a floating or mobile kidney
nephrostomy
the passage of a tube through the skin and into the renal pelvis to drain urine to a collecting receptacle outside the body when the ureters are unable to do so
stent placement
insertion of a mesh tube into a natural passage conduit in the body to prevent, or counteract a disease-induced, localized flow constriction
ureteral stent placement
Insertion of a thin narrow tube into the ureter to prevent or treat obstruction of urine flow from the kidney
urethrotomy
Incision of the urethral stricture
electromyography
Measures the contraction of muscles that control urination using electrodes placed in the rectum and urethra
cystoscopy (cysto)
Examination of the urinary bladder for evidence of pathology, obtaining biopsies of tumors or other growths, and removal of polyps using a specialized endoscope
blood urea nitrogen (BUN)
Determines the amount of nitrogen in blood that comes from urea, a waste product of protein metabolism
culture and sensitivity (C&S)
Determines the causative organism of an infection and identifies how the organism responds to various antibiotics
urinalysis (UA)
Urine screening test that includes physical observation, chemical tests, and microscopic evaluation
