Pelvic Organ Prolapse Flashcards
Definition
Pelvic organ prolapse refers to the descent of pelvic organs into the vagina. Prolapse is the result of weakness and lengthening of the ligaments and muscles surrounding the uterus, rectum, and bladder.
Uterine Prolapse
Where the uterus itself descends into the vagina
Vault prolapse
Occurs in women that have had a hysterectomy, and no longer have a uterus. The top of the vagina (the vault) descends into the vagina
Rectocele definition + characteristic sign
- Caused by a defect in the posterior vaginal wall, allowing the rectum to prolapse forwards into the vagina.
- Rectoceles are esp. associated with constipation.
= Women can develop faecal loading in the part of the rectum that has prolapsed into the vagina. Loading of faeces results in significant constipation, urinary retention (due to compression on the urethra) and a palpable lump in the vagina.
Women may use their fingers to press the lump backwards, correcting the anatomical position of the rectum, and allowing them to open their bowels.
Cystocele
Defect in the anterior vaginal wall, allowing the bladder to prolapse backwards into the vagina. Prolapse of the urethra is also possible (urethrocele). Prolapse of both the bladder and urethra = cystourethrocele
Aetiology
Result of weak and stretched muscles and ligaments.
Risk factors
- Multiple vaginal deliveries
- Instrumental, prolonged or traumatic delivery
- Advanced age and postmenopause status
- Obesity
- Chronic respiratory disease causing coughing
- Chronic constipation causing straining
Signs and symptoms
- A feeling of “something coming down” in the vagina
- A dragging or heavy sensation in the pelvis
- Urinary symptoms:
= incontinence,
= urgency,
= frequency,
= weak stream
= retention - Bowel symptoms,
= constipation,
= incontinence
= urgency - Sexual dysfunction:
= pain,
= altered sensation
= reduced enjoyment
Examination
Ideally Px should empty their bladder + bowel before.
When examining various positions may be attempted, including the dorsal and left lateral position
Sim’s speculum = U-shaped, single-bladed speculum that can be used to support the anterior or posterior vaginal wall while the other vaginal walls are examined. It is held on the anterior wall to examine the rectocele and the posterior wall for a cystocele.
The women can be asked to cough or “bear down” to assess the full descent of the prolapse
Grading of uterine prolapse
Severity of a uterine prolapse can be graded using the pelvic organ prolapse quantification (POP-Q) system:
- Grade 0: Normal
- Grade 1: The lowest part is more than 1cm above the introitus
- Grade 2: The lowest part is within 1cm of the introitus (above or below)
- Grade 3: The lowest part is more than 1cm below the introitus, but not fully descended
- Grade 4: Full descent with eversion of the vagina
A prolapse extending beyond the introitus can be referred to as uterine procidentia.
Management
There are three options for management:
- Conservative management
- Vaginal pessary
- Surgery
Conservative management
For women able to cope with mild symptoms, do not tolerate pessaries or are not suitable for surgery:
- Physio
- Wt loss
- Lifestyle changes for associated stress incontinence
= reduced caffeine
= incontinence pads
- Treatment of related symptoms
= stress incontinence with anticholinergic medications
- Vaginal oestrogen cream
Vaginal pessaries
Inserted into the vagina to provide extra support to the pelvic organs = Create a significant improvement in symptoms + can easily be removed and replaced. Types:
- Ring: sit around cervix
- Shelf and Gellhorn: flat disc with a stem = sits below uteris with the stem poiting downwards
- Cube
- Donut
- Hodge: almost rectangular, one side is hooked around the posterior aspect of the cervix and the other extends into the vagina
Side effect to pessaries
They can cause vaginal irritation and erosion over time. Oestrogen cream helps protect the vaginal walls from irritation.
Surgery complications
- Pain, bleeding, infection, - DVT and risk of anaesthetic
- Damage to the bladder or bowel
- Recurrence of the prolapse
- Altered experience of sex
