29 part 1Pelvic organ prolapse Flashcards
What is Pelvic organ prolapse
protrusion of bladder, rectum, intestines, uterus, cervix, or vaginal apex into the vaginal vault due to decreased pelvic floor support
Definition of pelvic organ prolapse
herniation or descent of pelvic organs into or beyond the vaginal walls
Types of prolapse
Partial/subtotal prolapse: The pelvic organs are only partially outside the vaginal opening.
Total prolapse: The pelvic organs are everted and located outside of the vaginal opening.
What is the anatomy of the pelvic floor
supported by a endopelvic fascia
Fascia consists of
1) Uterosacral ligament complex (suspends the uterus and vaginal apex from the sacrum and lateral pelvis)
2) Paravaginal attachments
3) Perineal body, perineal membrane, and the perineal muscles
5 specific cites of pelvic organ prolapse
Anterior vaginal wall prolapse: herniated anterior vaginal wall associated with -cystocele (descent of the bladder) or -urethrocele (descent of the urethra) can be due to weakness of the pubocervical fascia
Posterior vaginal wall prolapse: herniated posterior vaginal wall associated with 1)rectocele (descent of the rectum) 2)enterocele (herniated section of the intestines); can be due to weakness of the rectovaginal fascia
Uterine prolapse: descent of the uterus
Vaginal vault prolapse: descent of the apex of the vagina
Uterine procidentia: protrusion of all vaginal walls or cervix beyond the vaginal introitus
RF of pelvic organ prolapse
Anything that reduces strength of pelvic floor muscles and ligaments supporting the uterus and vagina e.g.
- Mx vaginal deliveries and/or traumatic births
- Low estrogen levels (menopause/OCP)
- Congenital connective tissue disorders
- Previous pelvic surgery (e.g., hysterectomy)
- Increase intraabdominal pressure (cough d/2chronic lung disease and/or smoking, ascites, obesity, pelvic tumors, or constipation.)
- Diabetes mellitus
Sx of POP
- vaginal fullness/ pressure around the perineum
- lower back pain worse w/ walking or standing
- weakened pelvic floor muscles
- weakened rectal sphincter
- anterior prolapse (cystocele) May present w/ discharge
What is the pelvic organ prolapse quantisation system
Means to clinically diagnose POP
Stage 0: no prolapse
Stage 1: The most distal portion of prolapse is more than 1 cm above the level of the hymen.
Stage 2: The most distal portion of prolapse is 1 cm or less proximal or distal to the hymenal plane.
Stage 3: The most distal portion of prolapse is more than 1 cm from the hymenal plane but no more than 2 cm less than the vaginal length.
Stage 4: The vagina is completely everted or uterine procidentia has occurred.
How is POP treated
Conservative:
For assymptomatic Prolapse
For pts who decline surgery
For pts who are CI for surgery
Surgical:
Symptomatic prolapse if conservative rx fails
Conservative rx types of POP
Vaginal pessary (to support the pelvic organs)
- short term rx as can cause ulcers
- need thorough cleaning
Reduce modifiable risk factors (e.g., avoid smoking to prevent a chronic cough, weight loss, prevent constipation)
Kegel exercises: pelvic floor muscle training (also prophylactic )
Surgical rx of POP
Obliterating surgery: closure of the vagina
Reconstructive surgery: restores descended pelvic organs to their original place
Four types of reconstructive surgery for POP
1) Sacrocolpopexy:
- Rx of apical or vaginal vault prolapse
- fix the vaginal apex to the sacrum, with hysterectomy- reduces recurrence
2) Suspension techniques:
- prolapsed organ is suspended using native tissues -e.g. endopelvic fascia, iliococcygeus muscle, uterosacral ligament, or sacrospinous ligaments.
3) Colporrhaphy:
- repair of cystocele or rectocele
- reinforce the anterior/posterior vaginal wall
4) Sacrohysteropexy:
- repair of uterine prolapse
- fixation of the cervix to the sacrum
What are the 6 complications of POP
1)Pressure ulcers w/ hemmorhage
2) Ascending urinary infections
- cystitis, pyelonephritis, vagina infec, endometritis
3) urinary disorders
- stress Incontinence
- obstructive uropathy d/2 ureter comrpression
4) defecation disorders constipation/ diahhrhea
5) sexual dysfunction fear and embarrassment
6) recurrence and surgical complications
