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
kidney, ureter, bladder (KUB) radiography
radiographic examination to determine the location, size, and shape of the kidneys in relationship to other organs in the abdominopelvic cavity and to identify abnormalities of the urinary system.
KUB radiography identifies stones and calcified areas and does not require a contrast medium
nuclear scan
radiology test in which radioactive materials called tracers are introduced into the patient and a specialized camera, which acts as a radiation detector produces images by recording the emitted tracers
renal: imaging test where a monitor is used to track a radioactive substance as it passes through the kidney
ultrasound
radiograph that uses high-frequency sound waves (ultrasound) and displays the reflected echoes on a monitor; also called sonography, echography, or echo.
US used to assess scrotal structures and patency of the vas deferens
voiding cystourethrography
radiological examination of the bladder and urethra performed before, during, and after voiding using a contrast medium to enhance imaging.
VCUG is performed to determine the cause of repeated bladder infections or stress incontinence and to identify congenital or acquired structural abnormalities of the bladder and urethra
dialysis
medical procedure used to filter toxic substances from the patient’s bloodstream, such as excess electrolytes and nitrogenous wastes.
Dialysis provides a means of removing waste products from the blood when kidneys no longer function. nitrogenous waste products are collected in a solution called dialysate, which is discarded at the end of the procedure. There are two primary methods of dialysis: hemodialysis and peritoneal dialysis
hemodialysis
method of removing waste substances from the blood by shunting it from the body, passing it through an artificial kidney machine where it is filtered, and then returning the dialyzed blood to the patient’s body
peritoneal dialysis
removal of toxic substances from the body by perfusing the peritoneal cavity with a warm, sterile chemical solution.
In peritoneal dialysis, the lining of the peritoneal cavity is used as the dialyzing membrane. dialyzing fluid remains in the peritoneal cavity for 1 to 2 hours and then is removed, The procedure is repeated as often as necessary
circumcision
removal of all or part of the foreskin, or prepuce, of the penis
nephropexy
fixation of a floating or mobile kidney
orchidectomy
removal of one or both testes; also called orchiectomy.
orchidectomy may be indicated for serious disease or injury to the testis or to control cancer of the prostate by removing a source of androgenic hormones
transurethral resection of the prostate (TURP)
surgical procedure that involves inserting a resectoscope into the urethra to “chip away” at the prostate gland to remove the obstruction and flushing out the chips and sending them for analysis to detect possible evidence of cancer.
TURP is used most commonly to relieve obstruction caused by benign prostatic hyperplasia. Because the prostate gland is not completely removed, remaining tissue eventually grows back and may cause obstruction again at a later time.
urethrotomy
incision of a urethral stricture.
urethrotomy corrects constrictions of the urethra that make voiding difficult.
vasectomy
excision of all or a segment of the vas deferens.
bilateral vasectomy is the most successful method of male contraception. although the procedure is considered permanent, with advances in microsurgery, vasectomy is sometimes reversible.
