Pelvic Organ Prolapse Flashcards

1
Q

Define prolapse and female pelvic organ prolapse (POP)

A
  • Prolapse, Protrusion of an organ or structure beyond its normal anatomical confines
  • Female POP, Refers to the descent of the pelvic organs towards or through the vagina

Q

3 layers of the pelvic floor

A
  • Endo-pelvic fascia
  • Pelvic diaphragm
  • Urogenital diaphragm

(They do not parallel each other and vary in thickness from place to place)

Q

Describe the endo-pelvic fascia

A
  • Network of fibro-muscular connective type tissue
  • Has “hammock like” configuration
  • Surrounds the various visceral structure
  • Fibro-muscular component can stretch (uterosacral)
  • Connective tissue does not stretch or attenuate but breaks

Q

Risk factors for POP

A
  • Pregnancy + vaginal delivery (forceps, macrosomia, prolonged 2nd stage)
  • Age
  • Obesity
  • Previous pelvic surgery
  • Occupation with heavy lifting
  • Exercise (weight lifting, long-distance running)

Parity is the single largest risk factor

Q

Define uterovaginal prolapse, enterocele and rectocele

A
  • Uterovaginal prolapse, Prolapse of uterus cervix and upper vagina
  • Enterocele, Upper post. wall of vagina, usually contains loops of small bowel
  • Rectocele, Lower post. wall of vagina involving rectum bulging forwards into vagina

Q

Problem with the traditional classification of POP

A
  • Implies an unrealistic certainty as to the structures on the other side of vaginal bulge
  • This is often a false assumption, particularly in women with previous prolapse surgery

Q

Assessment of POP

A

-Examination to exclude pelvic mass
-Record position of exam (left lateral/lithotomy/standing)
-QOL
-Objective assessment
Baden-walker grading
POPQ score(Gold standard)

17
Q

POP-Q gradings

A
  • Stage 0 (TVL-2cm)
  • Stage 1 (< - 1cm_
  • Stage 2 (> - 1cm = + 1cm)
  • Stage 3 (> 1cm but < + TVL - 2cm)
  • Stage 4 (>/= + TVL - 2cm)
18
Q

Investigations for POP

A
  • USS/MRI, allow identification of fascial defects
  • Urodynamics, concurrent UI or to exclude Occult SI
  • IVU or Renal USS, If suspicion of ureteric obstruction
19
Q

Prevention of POP

A
  • Avoid constipation
  • Effective management of chronic chest pathology (COPD & asthma)
  • Smaller family size
  • Improvements in antenatal and Intrapartum care(antenatal + post-natal PFMT [no evidence it works but logically it should] )
20
Q

Treatment for POP

A
  • Physiotherapy (PFMT)
  • Pessaries (silicone is favoured)
  • Surgery
21
Q

What is more effective pessaries or surgery

A

No difference at 1 year follow-up

22
Q

What causes POP

A

Progressive weakness of the pelvic floor muscles followed by the breakdown in fascial support

23
Q

Summary

A

Pelvic floor made from 3 distinct anatomical layers but function as 1 unit

  • Prolapse occur due to progressive weakness of the pelvic floor muscles followed by breakdown in fascial support
  • Affect 50% of multiparous women (10% asymptomatic)
  • Assessment includes pelvic exam, assessment of pelvic floor and QOL
  • Management is tailored to patients needs (PFMT, pessaries and surgery)
