In the POP-Q (Pelvic Organ Prolapse Quantification) system, point C describes:

• A The anterior vaginal wall at 3 cm proximal to the hymen
• B The most distal edge of the cervix or vaginal vault apex ✓
• C The posterior vaginal wall at 3 cm proximal to the hymen
• D The total vaginal length

Explanation

In the POP-Q system (International Continence Society standardisation), six vaginal reference points are measured relative to the hymen: Aa and Ba on the anterior wall; Ap and Bp on the posterior wall; C (cervix or vaginal vault apex — most distal point); and D (posterior fornix, measured only in women with a cervix). Point C therefore represents the cervical leading edge or post-hysterectomy vaginal cuff apex.
