GU test Flashcards
microscopic unit of the kidney
nephron
main artery leading into the kidney
renal
the renal artery is a direct branch off what major vesel?
aorta
3 of the layers that enclose the kidney
true capsule, renal fascia, peri renal fat
funnel shape uppermost end of the ureter
renal pelvis
two structures that compose the kidney pedicle
renal artery
renal vein
what space are the kidneys located in?
retroperitoneal space, between periotenum and back muscle
concave notch in the kidney through which the ureter, arteries and veins enter and exit
hilum notch
small triangular area near the mouth of the bladder, located between the ureteral orifice and urethra
trigone
largest metabolic waste constituent of urine?
urea
mucosal folds of the inner bladder
rugae
what what do the renal pyramids make up?
renal medulla
20-30cc of radiopaque dye is injected IV and time is noted when excretion begins from the kidneys
IV pyelogram or IV urogram
flat plate xray of the kidneys, ureters, bladder, demonstrating their size, shape, and location in relation to other pelvic organs
KUB
injection of radiopaque dye through a cystoscope using a ureteral catheter. Dye enters the ureters with back flow into the kidneys. done during a cystoscope
retrograde pyelogram
type of catheter whose primary function is to dilate narrow strictures of the urethra
filiforms and followers
BPH
benign prostate hyperplasia
is BPH a cancerous, malignant enlargement of the prostate?
no, false
what is hooked to the telescope?
light cord
what is hooked to the sheath?
irrigation
what is hooked to the working element?
bovie
irrigation tubing used in the cysto room that has 1 port
cysto tubing
irrigation tubing which has 2 ports, allowing 2 bags of fluid to be hung at 1 time
TUR tubing
alcohol, a bacteriostatic agent, is used for cleaning a cystoscope?
false
used to dilate the male urethra
van buren sounds
used to dilate female urethra
otis bougie
3 features a cysto table has that a regular OR table don’t have
wider, directly attached to xray, drainage pan attached
6 items you would find on a cysto set up?
lube, nipple, syringe, kelly, light cord, camera
sterile, isotonic, non hemolytic solution used during a TURP
sorbitol
where are the kidenys located?
under the dome of the diaphragm
are the kidneys located in the abd cavity?
NO
true capsule
smooth, transparent fibrous membrane INNERMOST LAYER
renal fascia
anchors kidney to surrounding structure- helps maintain position MIDDLE LAYER
peri renal fat
adipose tissue which acts as a cushion OUTERMOST LAYER
2 layers of kidneys
cortex, medulla
cortex of the kidney
outer layer
medulla of the kidney
inner layer, contains 8*12 renal pyramids
hilum notch
place where renal artery enters kidney and renal vein and ureter leave
renal calyces(calyx)
collect urine from renal pyramids
what does the renal vein drain directly into?
vena cava
what happens to the kidney pedicle during nephrectomy?
double clamped with pedicle clamp
what type of organ is the kdiney?
highly vascular
ureters
connect kidney to the bladder, peristalsis
space of retzius
area of tissue between symphsis pubis and bladder
urethra
transports urine out of body
functions of the urinary system
secretes unwanted waste, produces urea
urea
largest waste constituent of urine
where does urine formation take place?
nephrons
how much of urine is water?
95
GU surgeries male/females
male- reproductive and urinary tract
female-urinary tract ONLY
problems treated by urologist
incontinence, stones, tumors, cancer
open GU surgeries
performed in an OR room, involves incision
closed GU surgeries
performed in a cysto room, uses a scope
urinalysis
done prior to surgery, provides valuable info regarding function and health of urinary system
what does urinalysis measure?
cells, protein, sugar, clarity, specific gravity, pH
what is normally not in urine?
protein, sugar

suture using for GU procedures
chromic or vicrly SH q
what type of suture is never used on GU procedures?
non absorbable, provides as nucleus for stone formation
difference between urethral catheters and ureteral catheters?
urethral is larger
ureteral catheters
