Ch 10 Urinary System Flashcards
excretion
eliminating waste
functions of the kidneys
maintenance of appropriate blood volume by varying the excretion of water in the urine, maintenance of the chemical composition of blood by selecting certain chemicals to excrete, maintenance of blood pH, excretion of waste products of protein metabolism, regulation of blood pressure, stimulation of erythrocyte production by secretion of erythropoietin
-poietin
substance that causes production
final product of protein metabolism and the major nitrogenous waste product in urine
urea
ur/o
urinary tract
-logy
science of
albumin/o
albumin
-ation
proces
-esis
action, process, result of
glycos/o
sugar
olig/o
few, scanty
ur/o
urine or urinary tract
urin/o
urine
-uria
urine or urination
pertaining to urine or the formation of urine
urinary
parts of the urinary tract
(2) kidneys, (2) ureter, bladder, urethra
cyst/o
bladder (sometimes cyst or sac)
glomerul/o
glomerulus (filtering structure of the kidney)
nephr/o, ren/o
kidney
pyel/o
renal pelvis (reservoir in the kidney that collects the urine)
ureter/o
ureter
urethr/o
urethra
fibr/o
fiber
-ous
characterized by
functional unit of the kidney
nephron
glomerular filtration
filtering of the blood; initial process of urine
allows water, salts, wastes and most other substances, except blood cells and proteins, to pass through its thin walls
tubular reabsorption
selective reabsorption of some substances
Bowman’s capsule collects the substances that filter through the glomerular walls and passes them to a tubule
tubular secretion
secretion of substances into the urine
3rd process in urine formation
hormone that increases the reabsorption of water by the renal tubules
ADH (antidiuretic hormone)
U/A, UA
urinalysis
high concentration of albumin in the urine
albuminuria (proteinuria)
presence of pus in the urine
pyuria
py/o
pus
used to determine the specific gravity of a sample of urine
urinometer
presence of ketones in the urine
ketonuria
UTI
urinary tract infection
measure of the amount of urea in the blood, related to the metabolic function of the liver and the excretory function of the kidneys
BUN (blood urea nitrogen)
radiographic study to assess the arterial blood supply to the kidneys; requires injection of a radiopaque contrast agent into the renal arteries by a catheter
renal angiography (renal arteriography)
sectional radiographic examination of kidneys
nephrotomography
bladder hernia that protrudes into the vagina
cystocele
condition in which there are degenerative changes in the kidneys but no inflammation
nephrosis
destructive to kidney tissue
nephrotoxic
hereditary disorder characterized by hundreds of fluid-filled cysts throughout both kidneys
polycystic kidney disease
tumor found on a mucosal surface, such as the inner lining of the bladder
polyp
malignant neoplasm of the kidney; kidney cancer
renal cell carcinoma
failure of the kidney to perform its essential functions
renal failure
reduced ability of the kidney to perform its functions
renal insufficiency
ARF
acute renal failure
x-ray examination of the renal pelvis and ureter after injection of a contrast medium into the renal pelvis
retrograde urography
inability to hold urine in the bladder
urinary incontinence
inability to empty the bladder
urinary retention
infection of the urinary tract
UTI (urinary tract infection)
radiographic record of the bladder and urethra
voiding cystourethrogram
4 methods of urinary diversion
urethral, ureteral, suprapubic catheterization, percutaneous nephrostomy
ureteral catheterization
catheters passed into the distal ends of the ureters from the bladder and threaded up the ureters into the renal pelves
per-
through
process of diffusing blood through a membrane to remove toxic material and maintain proper chemical balance
hemodialysis
-eal
pertaining to
increasing urination or an agent that causes increased urination
diuretic
surgical removal of the donated kidney
nephrectomy
removal of the kidney through several small incisions in the abdominal wall, rather than an open surgical excision
laparoscopic nephrectomy
administration of agents that significantly interfere with the immune response of the recipient
immunosuppressive therapy
small pieces of tissue from a nearby structure are removed through the wall of the urethra
transurethral resection (TUR)
surgical creation of a new opening into the bladder
cystostomy
crushing of a stone
lithotripsy
instrument used for surgically crushing bladder stones
lithotrite
incision of the kidney
nephrotomy
incision of the kidney for removal of a kidney stone
nephrolithotomy
surgical attachment of a prolapsed kidney
nephropexy
removal of tissue from the bladder by using a needle inserted through the skin overlying the bladder =
percutaneous bladder biopsy
removal of tissue from the kidney using needle puncture of the skin and tissue overlying the kidney
percutaneous renal biopsy
surgical incision of the kidney to remove a stone from the renal pelvis
pyelolithotomy
surgical repair of a ureter
ureteroplasty
