In the POP-Q (Pelvic Organ Prolapse Quantification) system, which TWO reference points define the leading edge of the anterior vaginal wall prolapse?

• A Points Aa and Ba ✓
• B Points C and D
• C Points Ap and Bp
• D Points Aa and Ap

Explanation

In the POP-Q system, the anterior vaginal wall is measured at two points: Aa (a fixed point 3 cm proximal to the urethral meatus, analogous to the urethrovesical junction) and Ba (the most distal point of the anterior vaginal wall). Points C and D describe cervical and posterior fornix positions; Ap and Bp describe the posterior wall. The anterior compartment (cystocoele) is quantified by Aa and Ba.
