urinary system therapeutic and diagnostic Flashcards
Measures the contraction of muscles that control urination using electrodes placed in the rectum and urethra
electromyography
Examination of the urinary bladder for evidence of pathology, to obtain biopsies of tumors or other growths, or to remove polyps
cystoscopy
Test that determines the amount of nitrogen in blood that comes from urea, a waste product of protein metabolism
blood urea nitrogen
Test that determines the causative organism of an infection and identifies how the organism responds to various antibiotics
culture and sensitivity
Urine screening test that includes physical observation, chemical tests, and microscopic evaluation
urinalysis
A noninvasive painless test that uses high-frequency soundwaves to produce images of the bladder before and after urination to check for urinary retention
bladder ultrasound
Imaging of the urinary tract after IV injection of a contrast medium
intravenous pyelography
Nuclear imaging test using a radioactive substance (tracer) injected intravenously to produce images of the kidneys
renal nuclear scan
X-ray of the bladder and urethra performed before, during, and after voiding using a contrast medium to enhance imaging
voiding cystourethrography
Replacement of a diseased kidney with one that is supplied by a compatible donor (usually a family member or a cadaver who has donated the kidney before death)
kidney transplant
Opening created between the skin and kidney to drain urine through a tube to a collecting receptacle outside the body when the ureters are unable to do so
nephrostomy
Insertion of a thin, narrow tube into the ureter to prevent or treat obstruction of urine flow from the kidney
ureteral stent placement
Filtering procedure used to remove fluid and waste products from the blood and correct for electrolyte imbalances
dialysis
Dialysis in which an artificial kidney machine receives waste-filled blood, filters it using a solution called a dialysate, and then returns the dialyzed (clean) blood to the patient’s bloodstream
hemodialysis
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
