Female Reproductive System Flashcards
What are the 3 layers of the uterus
Endometrium - lining of uterus
Myometrium - contain 3 smooth muscle layers
Perimetrium
Function of cervix
- Maintains sterility of structures above it. Prevents bacterial invasion
- narrow external os
- thick cervical mucus
- shedding endometrium
- Guides passage of sperms to the uterus.
Where are the Bartholian’s gland ?
Either side of the vaginal opening
Other name - great vestibular gland
Secrete lubricant fluid during intercourse goes down the great vestibular duct.
Where are the Skenes glands located ? What is it ?
Either side of urethra.
Parautheral gland- another name
Secrete mucus during intercourse
Homologous with male scrotum
What nerve supplies the external genitalia and perineum?
Puodenal nerve - branch of sacral plexus
Origins - nerve root S2 ,3 and 4
Motor function - innervation of pelvic floor muscles
E.g . Levator ani muscles includ
Ilioccocygeus
Puboccocygeus
Puborectalis
Innervation of external anal sphincter ( inferior rectal nerve - branch of puodenal nerve. )and external urethral sphincter . Prevent incontinence.
Sensory - provides innervation to external genitalia.
S2, S3 ,S4 , KEEP POO AND WEE OF THE FLOOR AND GENITALIA .
Clinical significance of the nerve that supplies pelvic floor , external genitalia etc.?
Puodenal nerve block
Anaesthesia for minor vaginal surgeries e.g . Episiotomy.
Puodenal nerve accompanied by internal puodenal artery so need aspirate ( withdraw fluid - check there is no blood) so that the drug is not given into systemic circulation.
What are the sphincter which are involved in urination in females ?
External urethral sphincter
Compressor urethrae - wraps around urethra and contracts pressing urethra against vagina
Urethrovaginalis - wraps around urethra - contracts - compress urethra against vagina.
What are the spaces in the female peritoneal cavity?
Vesicouterine - space byw posterior wall of bladder and anterior wall of uterus
Pouch of Douglas / rectouterine pouch - btw posterior wall of uterus and rectum
Made by relections of peritoneum
Normal position of uterus and abnormal positions?
Normal - anti - flexed , anti - verted
Abnormal - retroverted , retroflexed, ante verted
What is Pelvic organ Prolapse?
0 1 or more of the organs of the Pelvis move out of position and bulge into the vagina.
4 stages with increasing severity
- Stage 1 - more than cm above hymen
- Stage 2 - Btw 1cm above or below hymen
- Stage 3 - More than 1cm below Hymen but 2cm shorter than total vaginal length
- Complete eversion - bascially inside out , uterus etc on the outside of the body.
- Stage 2 -
Different types of Prolapse ?
Cystocele - Anterior prolapse ( Bladder prolapses, dropping and pushes on the wall of the vagina.
- Rectocele - (posterior wall prolapse) Bulging of anterior wall of rectum into the posterior wall of the vagina.
- Uterine prolapse - Uterus slips down into vagina and protrudes out of it.
- Vaginal Vault prolapse - The vault (top of vagina ) drops from normal position and sags down. (can happen after hysterectomy)
Enterocele - Small intestine drops into pelvic cavity and presses on the top of vagina creating a bulge.
Urethocele - Urethra drops down into vagina.
Causes of Pelvic floor prolapse ?
weakened pelvic floor , so organs sag. Caused by :
Increased pressure on pelvic floor :
- pregnancy
* the more
children
you have
the more
at risk
you are
- overweight
- Chronic
constipation.
- Chronic
cough e.g
asthma ,
COPD
Reduced tissue collagen - White women more at risk of prolapse than black as they have weaker/ less collagen - genetic (things like marfan etc effect collagen )
- Hysterectomy - removal of uterus
- Heavy lifting.
- Age - menopause
more at risk -People with:
0 marfan ,
0 Joint hyper-mobility syndrome
0 Ehlers - Danlos syndrome - group of rare group of disorders that affect connective tissue.
Symptoms of Pelvic organ prolaspe ?
Pelvic or vaginal fullness - feel heaviness around lower tummy and genitals.
- sensation of organs falling out (of vagina )
- Bulging of organs into vaginal canal or through vaginal opening
- Stress incontinence - leaking of pee when cough , squeeze
- can have obscured stress incontinence )
- problems peeing - need to go to the toilet more often , or bladder not emptying fully (some urine left).
Rectocele
0 incomplete
defacation -
* Ask
patient
do you
need to
put you
fingers in
you
vagina to
promote
pooing
/bowel
motion?
0 Constipation
- certain prolapses can result in urinary retention (cant pass urine ) and can cause kidney infection / damage which can lead to kidney failure.
How do you assess someone with suspected Prolapse ?
Assessment
- History
- BMI
- Abdominal
and Vaginal
examination
0 Assess
degree of
prolapse
using
POP - Q -
pelvic
organ
prolapse
quantification
system.
0 Assess activity of pelvic floor muscle - bi-manual examination squeeze - insert a finger and ask them to squeeze around them. * some women stay they have been doing pelvic floor exercises but the squeeze test shows they are not doing it properly.
0 rule out pelvic mass or other pathology.
0 Assess vaginal atrophy.
Prolapse assessment
- maximal
valsalva
- sims speculum
- lithotomy position - lying on back , knees bent at 70 dg - knees supported
Management of Prolapse ?
Conservative - fix cause
0 lose weight -
if overweight
(from BMI) - greater than 30kg/m2
0 chronic
cough - refer
to respiratory
specialist ?
0 Physiotherapy
- pelvic floor exercises.
0 Chronic constipation - laxatives.
0 Miminse heavy lifting.
Pessaries
- many different types of pessary device - used for different types and severity of prolapse.
- Surgical
lifestyle changes and pessaries encouraged / used before surgery is considered.
