Q

blood urea nitrogen (BUN)

A

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

Q

prostate-specific antigen (PSA)

A

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

Q

urinalysis (UA)

A

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

Q

computed tomography

A

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

A

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.

Q

kidney, ureter, bladder (KUB) radiography

A

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

16
Q

nuclear scan

A

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

17
Q

ultrasound

A

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

18
Q

voiding cystourethrography

A

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

19
Q

dialysis

A

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

20
Q

hemodialysis

A

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

21
Q

peritoneal dialysis

A

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

22
Q

circumcision

A

removal of all or part of the foreskin, or prepuce, of the penis

23
Q

nephropexy

A

fixation of a floating or mobile kidney

24
Q

orchidectomy

A

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

25
Q

transurethral resection of the prostate (TURP)

A

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.

26
Q

urethrotomy

A

incision of a urethral stricture.

urethrotomy corrects constrictions of the urethra that make voiding difficult.

27
Q

vasectomy

A

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.
