Questions and Answers
How are the points measured in POP-Q?
6 points measured at the vagina with respect to the hymen; points above the hymen are assigned negative numbers and points below the hymen are assigned positive numbers.
What does 'Aa' refer to in POP-Q measurement?
Anterior vaginal wall 3cm proximal to the hymen, range -3cm to +3cm.
What is indicated by 'Ba' in the context of POP-Q?
Most distal position of the remaining upper anterior vaginal wall, -3cm to TVL.

Study Notes
POP-Q Flashcards Overview
- POP-Q (Pelvic Organ Prolapse Quantification) assesses prolapse using 6 key points measured from the hymen.
- Points above the hymen are given negative values, while those below receive positive values, facilitating clear assessment.
Key Measurement Points
- Aa: Anterior vaginal wall measured at 3cm proximal to the hymen, with a range from -3cm to +3cm.
- Ba: Most distal position of the upper anterior vaginal wall, measured from -3cm to total vaginal length (TVL).
- C: Refers to the most distal edge of the cervix or vaginal cuff scar.
- D: Corresponds to the posterior fornix, not applicable post-hysterectomy.
- Ap: Posterior vaginal wall at 3cm proximal to the hymen, also ranging from -3cm to +3cm.
- Bp: Most distal position of the upper posterior vaginal wall, similar measurement range as Ba.
- Genital Hiatus (gh): Measured from the middle of the external urethral meatus to the posterior midline hymen.
- Perineal Body (pb): Distance from the posterior margin of gh to the middle of the anal opening.
- Total Vaginal Length (tvl): Depth of vagina determined when point D or C is returned to its normal position.
Staging and Grading of Pelvic Organ Prolapse
- Stage 0: All points (Aa, Ap, Ba, Bp) at 3cm; C or D less than or equal to - (tvl - 2) cm.
- Stage I: Criteria for Stage 0 not met; leading edge between -1cm and +1cm, within two centimeters of tcl.
Grading of Pelvic Organ Prolapse
- Grading based on descriptors by Beecham and Baden & Walker.
- Grade 0: No prolapse.
- Grade 1: Descent halfway to hymen.
- Grade 2: Descent to hymen.
- Grade 3: Descent halfway past hymen.
- Grade 4: Maximum possible descent.
Staging of Pelvic Organ Prolapse
- Based on POP-Q values measured in centimeters.
- Stage 0: No prolapse.
- Stage 1: Prolapse >1cm above hymen.
- Stage 2: Prolapse within 1cm above or below hymen.
- Stage 3: Prolapse > 1cm below hymen, but less than TVL - 2cm.
- Distinctions important for clinical assessment, as a Grade 3 rectocele might be classified under Stage 2 if the leading edge aligns accordingly.
