Staging of pelvic organ prolapse

Evaluation/staging of pelvic organ prolapse

Two main systems are used for staging the degree of pelvic organ prolapse:

• Baden-Walker system
  
  
  • grade 0 - normal position for each respective site, no prolapse
  • grade 1 - descent halfway to the hymen
  • grade 2 - descent to the hymen
  • grade 3 - descent halfway past the hymen
  • grade 4 - maximal possible descent for each site
    
    
• Pelvic organ prolapse–quantification
  
  
  • stage 0 – no prolapse
  • stage I - > 1 cm above the hymen
  • stage 2 - ≤ 1 cm proximal or distal to the plane of the hymen
  • stage 3 - > 1 cm below the plane of the hymen, but protrudes no farther than 2 cm less than the total vaginal length
  • stage 4 - eversion of the lower genital tract is complete
