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.
