In the POP-Q (Pelvic Organ Prolapse Quantification) system, Stage II prolapse is defined as the leading edge of the prolapse being located:

• A More than 1 cm above the level of the hymen (−1 cm)
• B More than +1 cm but less than 2 cm beyond the hymen
• C At +3 cm or beyond the hymenal ring
• D Between −1 cm and +1 cm relative to the hymenal ring ✓

Explanation

POP-Q staging: Stage 0 — no prolapse, Stage I — leading edge >1 cm above hymen (< −1 cm), Stage II — leading edge between −1 cm and +1 cm (within 1 cm of hymen on either side), Stage III — more than +1 cm beyond hymen but less than total vaginal length minus 2 cm, Stage IV — total eversion (complete procidentia). Stage II represents clinically significant prolapse approaching or just at the introitus.
