Genitourinary Flashcards
function of urinary system
filter blood
create and excrete urine
organs of male GU system
testes
vas/ductus deferens
seminal vesicles
ejaculatory ducts
penis
6 paired male reproductive organs
testes
epididymides
seminal vesicles
ejaculatory ducts
bulbourethral glands
vas deferens (seminal ducts)
describe the kidneys
remove waste/filter blood
BP
hematopoiesis
vitamin D
regulate fluid balance
pH
location of kidneys
retroperitoneal space
either side of T12-L3
right lower than left
blood supply to kidneys
renal artery
renal parenchyma
nephron-Gerota’s capsule
external cortex, inner medulla
perirenal fat pad and fascia renalis
fatty areolar tissue
position and protect kidneys
hilum of kidney
medial side
concave where renal artery and vein enter, ureter, and lymphatics
renal pedicle
lymphatics of the kidney
renal pelvis
funnel structure posterior to vascular pedicle
divides into calyces
adrenal gland
retroperitoneal on top of the kidneys
hormones
adrenal regions
medulla: epinephrine, norepinephrine
cortex: steroids, hormones, cortisol, aldosterone, androgens
ureters
penal pelvis to bladder
25-30cm 4-5mm diameter
retroperitoneal
ureteral action to propel urine
peristalsis
3 areas of calculi in ureters
UPJ: ureteropelvic junction
UVJ: ureterovesical junction
ureteral point crossing over external iliac vessels
urinary bladder
hollow muscular
anterior pelvic cavity
capacity of bladder
600-800mL
trigone of bladder
triangle forms base
orifices of ureters in the neck
blood supply of bladder
superior, middle, inferior vesical arteries
urethra
internal urethral orifice to outside
male urethra
20-25cm
female urethra
3-5cm
6-8mm in diameter
why are females prone to UTI
less distance to travel
verumontanum
elevation in prostatic urethra where seminal ducts enter
prostate gland
donut shaped at base of bladder neck
prostate and urethra
surrounds urethra
lobes in prostate
4-5
weight of healthy prostate
20-30g
true prostatic capsule
separates prostate and seminal vesicles from rectum
surgical capsule
outer ring of normal tissue surrounding hyperplastic inner tissue
TURP
blood supply to prostate
pudendal, hemorrhoidal, inferior vesical arteries (from internal iliac arteries)
prostatic venous plexus –> vesical plexus –> internal iliac veins
BPH
increased size of prostate
who is affected by BPH
men over 50
two most common methods of diagnosing BPH
rectal exam
prostate specific antigen blood test
BPH vs. prostate cancer
BPH: limited to prostate
cancer: malignant spread to skeletal system/lungs
penis
shaft: corpus spongiosum houses urethra
corpora cavernosa: 2 lateral
root with crura
vascular bodies for erection
corpus spongiosum urethrae
2 corpora cavernosa
prepuce (foreskin)
mucous membrane covering glans
scrotum
sac protecting testes
epididymides located within
tunica vaginalis
smoothing glistening membrane sac covering testes
testes
paired ovoid in scrotum
4-5cm long
3cm wide
2cm thick
testosterone, endocrine glands
epididymides
long convoluted duct –> vas deferens
final maturation and storage of sperm
vasa deferentia
paired continuations of epididymides –> ejaculatory ducts via peristalsis
spermatic cord
suspends testes in scrotum
vas deferens, vessels, cremaster muscle, nerves, lymphatics
ejaculatory ducts
paired tubes formed by union of seminal vesicles and vas deferens
sperm to urethra
seminal vesicles
paired at base/fundus of bladder and prostate
nourish sperm
bulbourethral glands
mucous secretions into urethra on either side of membranous and bulbar urethra
intravenous pyelogram/urogram
enhancement of KUB
contrast into a vein into kidney
retrograde pyelogram/urogram
contrast into ureters with a cystoscope
KUB
anterior to posterior x-ray for size, shape, position, stones
PSA blood test
prostate specific antigen
digital rectal exam
finger up rectum to check prostate size
topical anesthetic for cystoscopy
viscous lidocaine jelly
topical anesthetic for male
into urethra after prep and drape with urojet
topical anesthetic for female
cotton applicator into urethral meatus
why use sterile irrigation for cystoscopy
distend, visualize
irrigating fluid for simple surgical cysto
sterile water
distilled water
CHECK
irrigating fluid for TURP
3% sorbitol
1.5% glycine
special irrigating fluid in TURP
isotonic and nonelectrolytic to allow electrical transmission

sheath
obturator
telescope
light source

electrical current to excise tissue from bladder, urethra, prostate
4 types of resectoscope
Iglesias
Nesbit
Baumrucker
Stern-McCarthy
Bugbee electrode
in Brown-Buerger or Wrappler to fulgurate bladder tumors, control bleeding, ureteral meatotomy
