Pelvic Organ Prolapse

POP: Intro & Risks - Downward Spiral Starters

  • Definition: Pelvic Organ Prolapse (POP) is the descent or herniation of pelvic organs (bladder, uterus, rectum) into or beyond the vaginal walls.
  • Prevalence: A common condition, significantly impacting quality of life, especially in post-menopausal women.
  • Risk Factors: 📌 POPULAR
    • Parity: Multiparity is key.
    • Obesity: Increased intra-abdominal pressure.
    • Pelvic surgery/trauma: e.g., hysterectomy, forceps delivery.
    • Urogenital atrophy: Post-menopause.
    • Lifestyle: Chronic cough, constipation, heavy lifting.
    • Age: Advancing age weakens tissues.
    • Race/genetics: Connective tissue disorders (e.g., Marfan, Ehlers-Danlos).

⭐ Multiparity is the single most important risk factor for developing Pelvic Organ Prolapse.

POP: Anatomy & Pathophysiology - Holding It Together

  • Pelvic Diaphragm:
    • Levator ani: Pubococcygeus, iliococcygeus, puborectalis. 📌 Mnemonic: "PIP" (Pubococcygeus, Iliococcygeus, Puborectalis).
    • Coccygeus muscle.
  • Endopelvic Fascia: Connective tissue support.
    • Pubocervical (anterior), Rectovaginal (posterior).
  • Ligamentous Support: Key for uterine/vaginal position.
    • Uterosacral, Cardinal ligaments.
  • DeLancey's Levels (Vaginal Support): 📌 "SAF":
    • Level I (Suspension): Apical (uterosacral-cardinal complex).
    • Level II (Attachment): Mid-vaginal (paravaginal to arcus tendineus).
    • Level III (Fusion): Distal (perineal body, urogenital diaphragm).
  • Pathophysiology: Damage to nerves (e.g., pudendal), muscles (levator ani), connective tissue (fascia, ligaments) from childbirth, aging, ↑intra-abdominal pressure.

⭐ DeLancey's Level I support (apical suspension by uterosacral-cardinal ligament complex) is most critical for preventing uterine and vault prolapse. oka

POP: Types & Symptoms - What's Dropping?

  • Types of Pelvic Organ Prolapse:
    • Anterior vaginal wall prolapse:
      • Cystocele (bladder drops)
      • Urethrocele (urethra drops)
    • Posterior vaginal wall prolapse:
      • Rectocele (rectum bulges)
      • Enterocele (small bowel herniates)
    • Apical prolapse:
      • Uterine prolapse (uterus descends)
      • Vaginal vault prolapse (post-hysterectomy)
  • Common Symptoms:
    • Primary: Vaginal bulge or pressure sensation.
    • Urinary: Stress urinary incontinence (SUI), urgency, frequency, retention, recurrent UTIs.
    • Bowel: Constipation, incomplete evacuation, need for splinting.
    • Sexual: Dyspareunia (painful intercourse), altered sensation.
    • Other: Low backache.

Types of Pelvic Organ Prolapse

⭐ Anterior vaginal wall prolapse (cystocele) is the most common type of pelvic organ prolapse.

POP: Diagnosis & Staging - Grading the Drop

  • Clinical Exam: Dorsal lithotomy, Sims, bimanual, Valsalva.
  • POP-Q System:
    • 📌 (Aa-tvl): Aunt Betty Can Dance, And Paul Brings Good Party Tunes.
    • 9 points; hymen 0cm. Measure cm (-ve proximal, +ve distal). POP-Q Measurement Points for Pelvic Organ Prolapse
  • POP-Q Stages (Maximal prolapse to hymen 0cm):
    • Stage 0: No prolapse. Aa,Ap,Ba,Bp -3cm; C/D ≤-(tvl-2)cm.
    • Stage I: Distal prolapse >1cm above hymen (<-1cm).
    • Stage II: Distal prolapse -1cm to +1cm from hymen.

      ⭐ POP-Q: standardized, objective quantification.

    • Stage III: Distal prolapse >1cm below hymen, <(tvl-2)cm.
    • Stage IV: Complete eversion; prolapse ≥(tvl-2)cm.
  • Investigations: Urinalysis, PVR. Urodynamics (UI, voiding issues, pre-op).

POP: Management - Lifting Spirits Up

Goals: Relieve symptoms, restore anatomy & function.

  • Conservative: Lifestyle changes (weight, constipation/cough), Pelvic Floor Muscle Training (PFMT/Kegels).
  • Pessaries: Ring, Gellhorn. For patient preference, surgical unfitness, bridge to surgery, pregnancy.
  • Surgical:
    • Reconstructive: Colporrhaphy, sacrospinous fixation, sacrocolpopexy (mesh).
    • Obliterative: Colpocleisis (LeFort). Choice: Age, stage, symptoms, sexual activity, comorbidities.

Types of Pelvic Organ Prolapse

⭐ Sacrocolpopexy is the gold standard for apical vaginal prolapse in sexually active women desiring durable repair.

High‑Yield Points - ⚡ Biggest Takeaways

  • Cystocele (anterior prolapse) is the most common type.
  • Risk factors: Multiparity, obesity, chronic cough/constipation, connective tissue weakness.
  • Symptoms: Pelvic pressure/heaviness, vaginal bulge, urinary/bowel/sexual dysfunction.
  • POP-Q system is the gold standard for objective staging (0-IV).
  • Conservative management: Pelvic floor muscle training (PFMT/Kegels), pessaries.
  • Surgical options: Colporrhaphy (anterior/posterior repair), sacrocolpopexy (apical support).
  • Enterocele: Prolapse of small bowel into upper posterior vagina, common post-hysterectomy.
