Uterine Prolapse

★ CMTO Exam Focus

Uterine prolapse is the descent of the uterus into or beyond the vaginal canal due to weakening and failure of the pelvic floor muscles, fascia, and ligaments that normally support it. It exists on a spectrum from mild descent (Grade 1) to complete protrusion outside the vaginal opening (Grade 4, procidentia). It frequently co-occurs with cystocele (bladder prolapse) and rectocele (rectal prolapse). Prone positioning and deep abdominal massage are both inappropriate for significant prolapse, as they increase intra-abdominal pressure and worsen symptoms.

Populations and Risk Factors

  • Women with history of vaginal deliveries — particularly multiple births, large infants, prolonged second stage, forceps use
  • Post-menopausal women — estrogen decline reduces connective tissue quality and pelvic floor tone
  • Chronic increases in intra-abdominal pressure: obesity, chronic cough (COPD, asthma), constipation, heavy lifting occupations
  • Prior pelvic surgery that disrupts supportive structures
  • Connective tissue disorders (Ehlers-Danlos syndrome, Marfan syndrome)

Causes and Pathophysiology

  • Pelvic support anatomy: The uterus is supported by the cardinal ligaments, uterosacral ligaments, round ligaments, and pelvic floor musculature (levator ani)
  • Progressive failure: Obstetric trauma, estrogen loss, and repetitive straining cause progressive ligamentous laxity and muscle atrophy. As support fails, gravity and intra-abdominal pressure displace the uterus inferiorly
  • Grading (Baden-Walker system): Grade 1 — uterus in upper vagina. Grade 2 — at the introitus. Grade 3 — partial protrusion beyond opening. Grade 4 — complete procidentia
  • Associated prolapse: Cystocele (anterior vaginal wall/bladder) and rectocele (posterior vaginal wall/rectum) frequently accompany uterine prolapse

Signs and Symptoms

  • Pelvic pressure or heaviness: Sensation of "something falling out" — worse with prolonged standing or activity. Relieved supine
  • Low back pain and pelvic discomfort from traction on supporting structures
  • Urinary symptoms: stress incontinence, urgency, incomplete emptying, recurrent UTIs
  • Bowel symptoms: difficulty defecating, incomplete emptying
  • Visible or palpable protrusion in Grade 3-4
  • Dyspareunia (painful intercourse)
  • Red flags: New urinary retention or inability to void suggests severe prolapse with urethral kinking — urgent referral

CMTO Exam Relevance

  • Uterine prolapse is a pelvic floor dysfunction condition — frequently co-occurs with stress urinary incontinence
  • Prone positioning is generally inappropriate for significant prolapse (Grade 2+) — increases intra-abdominal pressure and worsens symptoms
  • Abdominal massage is not indicated — deep pressure increases intra-abdominal pressure and aggravates prolapse
  • Pelvic floor physiotherapy is the primary conservative treatment — MT complements by addressing hip flexors, posterior pelvic musculature, and lumbar region

Massage Therapy Considerations

  • No systemic contraindication: Prolapse does not prevent treatment of other body regions
  • Positioning: Supine is generally comfortable. Avoid prolonged prone (increases intra-abdominal pressure). Side-lying or semi-reclined preferred
  • Abdominal massage: Avoid deep abdominal pressure in any grade of active prolapse. Superficial techniques may be used with caution and client communication
  • Lumbopelvic work: Appropriate and beneficial — hip flexor lengthening, posterior pelvic and gluteal release, sacral work reduce pelvic mechanical strain
  • Pessary users: Clients wearing a vaginal pessary should not be positioned in ways that dislodge or create discomfort — ask about comfort
  • Psychological sensitivity: Prolapse carries significant body image concerns — use neutral, clinical language during intake

Key Takeaways

  • Uterine prolapse is descent of the uterus due to pelvic floor and ligamentous failure — graded 1-4 by degree
  • Primary risk factors: multiple vaginal deliveries, menopause, chronic straining
  • Avoid prone positioning and deep abdominal massage — both increase intra-abdominal pressure and worsen symptoms
  • Lumbopelvic soft tissue work is appropriate and complements pelvic floor physiotherapy
  • Approach the condition with clinical sensitivity — use professional, neutral language
