POP-Q Staging
POP-Q prolapse staging from points Aa, Ba, C, D, Ap, Bp and total vaginal length (cm); the leading (most positive) edge sets the stage 0–IV.

Example
- Point Aa
- 2 cm
- Point Ba
- 3 cm
- Point C
- -2 cm
- Point D
- -6 cm
- Point Ap
- -3 cm
- Point Bp
- -3 cm
- Total vaginal length
- 9 cm
Result: POP-Q stage III: leading edge +3 cm at point Ba.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Leading edge
- the most positive of Aa, Ba, C, D, Ap, Bp (cm relative to the hymen at 0).
- Stage 0 / I / II
- no descent / leading edge < -1 cm / within 1 cm of the hymen.
- Stage III / IV
- > +1 cm but < +(TVL-2) / essentially complete eversion (>= +(TVL-2)).
What you enter
- Point Aa
- Point Ba
- Point C
- Point D (absent after hysterectomy)
- Point Ap
- Point Bp
- Total vaginal length
