pelvic organ prolapse classification stages diagram

This clinical photograph demonstrates a severe case of stage IV pelvic organ prolapse (procidentia) in a patient. The image shows a large, cylindrical, pinkish-red mass of tissue protruding entirely beyond the vaginal introitus and lying on the vulva. The visible structures include the everted anterior and posterior vaginal walls and the uterine cervix, which occupies the most distal portion of the prolapsed mass. The surface texture of the prolapsed tissue appears moist and slightly lobulated with visible rugae. This visual representation illustrates maximal descent of pelvic organs as defined by the Pelvic Organ Prolapse Quantification (POP-Q) system, where the entire vaginal length is essentially everted. The clinical context suggests a profound failure of the pelvic floor support structures, including the cardinal and uterosacral ligaments. This material is highly relevant for medical education in gynecology, specifically for identifying advanced stages of pelvic floor dysfunction and understanding the anatomical landmarks involved in total vault prolapse.

Here is a comprehensive overview of pelvic organ prolapse (POP) management, drawn from Berek & Novak's Gynecology and Campbell-Walsh-Wein Urology.

Pelvic Organ Prolapse (POP) - Management

Definition

POP is defined as the "descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus (cervix), or the apex of the vagina (vaginal vault or cuff scar after hysterectomy)," correlated with symptoms. Women with prolapse beyond the hymen may also report lower urinary tract (incontinence, urgency-frequency, voiding difficulty) and bowel (obstructed defecation, fecal incontinence) symptoms. - Berek & Novak's Gynecology, p. 1594

Classification: POP-Q System

The Pelvic Organ Prolapse Quantification (POP-Q) system is the validated standard for staging prolapse. Nine anatomical reference points are measured (Aa, Ba, C, D, Ap, Bp, gh, pb, tvl) relative to the hymen:
POP-Q Staging System
StageDescription
Stage 0No prolapse
Stage IMost distal point > 1 cm above hymen
Stage IIMost distal point between -1 cm and +1 cm of hymen
Stage IIIMost distal point > 1 cm beyond hymen but < total vaginal length - 2 cm
Stage IVComplete eversion; most distal point ≥ total vaginal length - 2 cm

Three Compartments of Prolapse

CompartmentDefectCondition
AnteriorBladder herniation through anterior wallCystocele
ApicalUterine/cervical descent or vaginal vault after hysterectomyUterine prolapse / Vault prolapse
PosteriorRectal mucosa herniation through posterior wallRectocele; enterocele (bowel through pelvic floor)
Enterocele is more common following hysterectomy and retropubic urethropexy.

Evaluation

  • Symptoms: Vaginal bulge (cardinal symptom), pelvic pressure (worse in afternoon/after activity), urinary symptoms (voiding difficulty, urgency, incontinence), defecatory dysfunction, sexual dysfunction, and the need to manually reduce the prolapse to void/defecate
  • Physical examination: Assess all three compartments with maximal Valsalva; note position of uterus/cuff
  • POP-Q staging for documentation and longitudinal follow-up
  • Pelvic muscle function assessment (levator ani integrity)
  • Bladder/bowel evaluation for co-existing dysfunction
  • Imaging (MRI/dynamic defecography) when functional disorders coexist

Management

1. Non-Surgical (Conservative) Treatment

a. Pelvic Floor Muscle Training (PFMT)

  • First-line for mild-to-moderate symptomatic POP
  • Structured Kegel exercises reduce prolapse symptoms and may slow progression
  • Most beneficial when initiated early, ideally with physiotherapist supervision

b. Pessary Therapy

Pessaries are the primary non-surgical mechanical device. They are safe alternatives to surgery and have been used for centuries.
Types of Pessaries
Types:
  • Supportive pessaries (ring with/without support, Shaatz, Regula) - for 1st and 2nd degree prolapse
  • Space-occupying pessaries (Gellhorn, cube, donut, Inflatob) - for 3rd degree / severe prolapse; use suction or pressure mechanism
  • For cystocele/rectocele: Gehrung pessary; Gehrung with knob for cystocele + SUI
Fitting principles:
  • Trial-and-error fitting - changing size or type at least once after initial fitting is common
  • Correctly sized pessary: patient cannot feel it; too small = falls out; too large = discomfort or erosion
  • Reassess at 1-2 weeks, then 4-6 weeks post-fitting; thereafter every 6-12 months
Outcomes:
  • Improves quality of life, body image, and urinary/bulge symptoms
  • Long-term success factors: age ≥72 years, careful fitting, clear patient instructions
  • Concomitant vaginal estrogen helps prevent tissue erosion and infection
Complications: Increased vaginal discharge, erosion/ulceration of vaginal wall, infection (if neglected)

2. Surgical Treatment

Surgical management is individualized and multicompartmental. Key decision axes:
  • Approach: Vaginal vs. abdominal (open/laparoscopic/robotic)
  • Type: Reconstructive vs. obliterative
  • Material: Native tissue vs. graft (biologic or synthetic mesh)

A. Apical Compartment

Vaginal approaches (native tissue):
  • Sacrospinous ligament suspension (SSLS) - most widely used vaginal apical repair; sutures fix vaginal apex to sacrospinous ligament
  • Uterosacral ligament suspension (USLS) - sutures placed at ischial spine level; bilateral technique
The OPTIMAL RCT (374 women, POP-Q stage II-IV) compared these two:
  • No significant difference in composite success (absence of apical descent, bothersome symptoms, retreatment)
  • 2-year success: 59% (USLS) vs. 61% (SSLS)
  • 5-year success declined to 44% (USLS) and 33% (SSLS) - Berek & Novak's Gynecology, p. 1628
Uterine preservation options:
  • Sacrospinous hysteropexy
  • Manchester procedure (with cervical amputation)
  • Considered in women desiring uterine preservation
Abdominal approaches:
  • Abdominal sacrocolpopexy - polypropylene mesh sutured from vaginal apex to sacral promontory; considered the gold standard for apical prolapse repair, especially vault prolapse
  • Laparoscopic/robotic sacrocolpopexy - equivalent outcomes with less morbidity; preferred approach in many centers
  • Abdominal uterosacral suspension - open/laparoscopic fixation of cuff to uterosacral ligaments

B. Anterior Compartment (Cystocele)

  • Anterior vaginal colporrhaphy - standard repair; midline plication of pubocervical fascia; recurrence rates 3-92% (wide due to varying definitions)
  • Paravaginal repair - restores lateral attachment of anterior vaginal wall to arcus tendineus fascia pelvis (ATFP); useful for lateral/displacement cystocele
  • Mesh augmentation (transvaginal or transabdominal) - improves anatomic outcomes but increases risk of mesh erosion and dyspareunia; requires careful patient counseling
  • Midurethral sling can be added simultaneously if stress incontinence is present

C. Posterior Compartment (Rectocele / Enterocele)

  • Posterior colporrhaphy - most common repair; plication of rectovaginal septum ± perineorrhaphy; anatomic cure 76-96%; ineffective for constipation; de novo dyspareunia 7-26% (less with avoiding levator plication)
  • Site-specific (defect-directed) repair - identifies and repairs discrete fascial tears; may have better functional outcomes
  • Transanal repair - colorectal approach; avoided by most gynecologists due to higher dyspareunia
  • Abdominal sacral colpoperineopexy - for perineal descent syndrome
  • Culdoplasty - performed when enterocele is present (McCall, Halban, Moschowitz techniques)
Rectocele repair is indicated for bothersome prolapse bulge symptoms, NOT for the purpose of correcting disordered defecation. Literature does not support rectovaginal reinforcement procedures for improving constipation. - Berek & Novak's Gynecology, p. 1723

D. Obliterative Procedures

  • Le Fort partial colpocleisis / total colpocleisis - suitable for elderly, sexually inactive women with high surgical risk; very high success rates; irreversible
  • Not appropriate for women who wish to maintain penetrative sexual function

3. Management of Concomitant Urinary Symptoms

  • Occult stress incontinence (unmasked after prolapse reduction) should be assessed pre-operatively with a pessary reduction test
  • Midurethral sling (tension-free vaginal tape / transobturator tape) can be placed simultaneously with prolapse repair
  • Voiding dysfunction with high post-void residual: urodynamic evaluation first; patient counseled on potential for continued problems post-surgery

Surgical Approach Comparison

FactorVaginalAbdominal/Laparoscopic
RecoveryFasterLonger
Apical successModerate (44-61% at 2-5 yr)Higher (sacrocolpopexy)
Mesh erosionHigher (transvaginal mesh)Lower (abdominal mesh)
AccessBetter for elderly/frailBetter for younger, sexually active
Obliterative optionYes (colpocleisis)No

Special Populations

Elderly women:
  • POP is particularly prevalent due to tissue changes (progressive loss of smooth/striated muscle, increased collagen)
  • Pessaries are very well tolerated; long-term success higher in age ≥72
  • Surgery is feasible and most women return to baseline function
  • Visiting nurse services can assist with pessary maintenance if cognitive/motor impairment present
  • Campbell-Walsh-Wein Urology, p. 3860

Recent Evidence (2024-2026)

A Cochrane review on perioperative interventions in POP surgery (Shahid et al., Cochrane Database Syst Rev, July 2025) provides updated guidance on perioperative care. A systematic review on hysterectomy and pelvic floor disorders (Chang et al., Am J Obstet Gynecol, 2025) confirms the relationship between prior hysterectomy and increased POP risk.
