Genitourinary System Diagnostic and Therapeutic procedures Flashcards
electromyography
measures the contraction of muscles that control urination using electrodes placed in the rectum and urethra.
EMG determines whether incontinence is due to weak muscles or other causes
digital rectal examination (DRE)
screening test that assesses the rectal wall surface for lesions or abnormally firm areas that might indicate cancer.
In DRE, the physician inserts a gloved, lubricated finger into the rectum. In males, the physician also evaluates the size and consistency of the prostate
testicular self examionation
self examination of the testes for abnormal lumps or swellings in the scrotal sac.
testicular cancer is the number one cancer killer in men ages 20 to 30
cystoscopy
endoscopy of the urinary bladder for evidence of pathology, obtaining biopsies of tumors or other growths, and removal of polyps.
a catheter can be inserted through the hollow channel in the cystoscope to collect tissues samples or introduce contrast media during radiography
nephroscopy
endoscopy of the kidneys using a specialized three channel endoscope that enables visualization and irrigation of the kidney.
the nephroscope is passed through a small incision made in the renal pelvis
urethroscopy
endoscopy of the urethra using a specialized endoscope, typically for lithotripsy or TURP
blood urea nitrogen (BUN)
test that determines the amount of urea nitrogen, a waste product of protein metabolism, present in a blood sample.
because urea is cleared from the bloodstream by the kidneys, the BUN test is used as an indicator of kidney function
culture and sensitivity (C&S)
test that determines the causative` organism of a disease and how the organism responds to various antibiotics.
C&S tests are performed on urine, blood, and body secretions
prostate-specific antigen (PSA)
Blood test used to detect prostatic disorders, especially prostatic cancer.
PSA is a substance produced by the prostate and is normally found in a blood sample in small quantities. The level is elevated in prostatitis, benign prostatic hyperplasia, and tumors of the prostate
semen analysis
test that analyzes a semen sample for volume, sperm count, motility, and morphology to evaluate fertility or verify sterilization after a vasectomy
urinalysis (UA)
battery of tests performed on a urine specimen, including physical observation, chemical tests, and microscopic evaluation.
UA not only provides information on the urinary structures but may also be the first indicator of such system disorders as diabetes and liver and gallbladder disease
computed tomography
imaging technique that rotates an x-ray emitter around the area to be scanned and measures the intensity of transmitted rays from different angles.
in the genitourinary system, CTs are used to diagnose tumors, cysts, inflammation, abscesses, perforation, bleeding, and obstructions of the kidneys, ureters, and bladder
cystography
radiographic examination of the urinary bladder using a contrast medium.
cystography is used to diagnose tumors or defects in the bladder wall, vesicoureteral reflux, stones, or other pathological conditions of the bladder
cystometrography
procedures that assesses volume and pressure in the bladder at various stages of filling using saline and a contrast medium introduced into the bladder through a catheter.
it is the primary test used to investigate stress incontinence and urge incontinence
intravenous pyelography (IVP)
radiographic examination of the kidneys, and urinary tract after IV injection of a contrast medium; also called excretory urography
