According to the POP-Q (Pelvic Organ Prolapse Quantification) system, Stage III prolapse is defined as:

• A Leading edge of prolapse is exactly at the level of the hymen (0 cm)
• B Most distal prolapse is >1 cm above the hymen
• C Leading edge of prolapse is >1 cm beyond the hymen but not complete eversion ✓
• D Complete vaginal eversion (vault prolapse)

Explanation

POP-Q staging: Stage 0 = no prolapse; Stage I = leading edge >1 cm above hymen (−1); Stage II = leading edge between −1 and +1 cm of hymen; Stage III = leading edge >1 cm beyond hymen (>+1 cm) but not maximum possible descent; Stage IV = complete eversion (leading edge ≥TVL−2 cm). Stage III represents significant prolapse outside the introitus but not total vault descent.
