A 55-year-old multiparous woman has a prolapse in which the cervix descends 2 cm beyond the hymenal ring. The leading point is at +2 cm on POP-Q examination. Stage of prolapse according to POP-Q is:
- A Stage I
- B Stage II
- C Stage III ✓
- D Stage IV
Explanation
POP-Q staging: Stage 0 = no prolapse; Stage I = leading point > 1 cm above the hymen; Stage II = leading point between −1 cm and +1 cm (at or near the hymen); Stage III = leading point > 1 cm beyond the hymen but prolapse is not complete eversion (within 2 cm of total vaginal length); Stage IV = complete eversion. Leading point at +2 cm is more than 1 cm beyond the hymen but not complete eversion → Stage III.
