Pelvic Organ Prolapse

About

  • Downward descent of female pelvic organs including the bladder, uterus and the small/large bowel, resulting in protrusion of the vagina, uterus or both
  • 4 Main Types:
    1. Cystocele/Dropped Bladder: Protrusion involves the front (posterior wall) of the vagina and rectum (Most common type)
    2. Rectocele: Involves the back (posterior wall) of the vagina and rectum
    3. Enterocele: Involves the upper portion of the vaginal wall and small bowel
    4. Uterine Prolapse: When the uterus descends downwards

Causes

  • Anything that puts increased pressure in the abdomen
  • Pregnancy, labour and childbirth
  • Obesity
  • Constipation
  • Pelvic organ cancers
  • Hysterectomy
  • Genetics
  • Connective tissue disorders
  • Selective estrogen-receptor modulators
  • Advancing age

Symptoms

  • Vaginal
    • Sensation of a bulge/protrusion
    • Seeing or feeling a bulge/protrusion
    • Pressure
    • Heaviness
  • Urinary
    •  Incontinence
    •  Urgency
    •  Frequency
    • Weak/prolonged urinary stream
    •  Hesitancy
    • Feeling of incomplete emptying
    • Manual reduction of prolapse to start/complete voiding
    • Position change to start/complete voiding
  • Bowel
    • Incontinence of flatus, or liquid or solid stool
    • Feeling of incomplete emptying
    • Straining during defecation
    • Urgency to defecate
    • Digital evacuation to complete defecation
    • Splinting/pushing on or around the vagina/perineum, to start of complete defecation
  • Sexual:
    • Dyspareunia (pain with sex)
    • Decreased sexual desire due to body image issues associated with prolapse

Diagnosis

  • Routine pap smear
  • Pelvic ultrasound
  • Intravenous Pyelogram (IVP): Urinary tract x-ray
  • CT/MRI scan: Of the pelvis

Treatment

  • Pelvic Physiotherapy: To strengthen the pelvic floor muscles
  • Pessary: Device is inserted into the vagina to provide support to related pelvic structures and to relieve pressure on the bladder and bowel
    • A wide variety of pessaries (made of silicone/plastic) are available for those who are not candidates for surgery or have temporary issues post-pregnancy
    • Fitted based on the nature and extent of the prolapse and the patient’s cognitive status, manual dexterity and level of sexual activity
    • Size of the vagina is estimated and the appropriate size and shape of pessary is inserted to effectively reduce the prolapse
  • Reconstructive Surgery: Aims to correct the prolapsed vagina while maintaining/improving vaginal sexual function and relieving any associated pelvic symptoms
    • Can be done through an abdominal incision/laparoscopically/vaginally
  • Sacrocolpopexy Surgery: Suspends the upper vagina with synthetic mesh
      • Can be done through an abdominal incision/laparoscopically
  • Vaginal Surgery: Either the upper vagina/cervix is attached to the ligament between the ischial spine and the sacrum (sacrospinous ligament) or to the ligaments between the sacrum and uterus (uterosacral ligaments)
  • Obliterative Surgery: Closes off the vaginal canal either partially/completely
    • Typically reserved for women who are no longer sexually active
