In the POP-Q (Pelvic Organ Prolapse Quantification) system, a woman has point Ba at +1, C at +4, D at +1, and total vaginal length (tvl) of 9 cm. The prolapse is BEST classified as:

• A Stage II
• B Stage IV
• C Stage I
• D Stage III (leading edge beyond the hymen but within tvl − 2 cm) ✓

Explanation

POP-Q Stage III is defined as the leading edge of prolapse more than 1 cm beyond the hymen (> +1 cm) but not yet complete eversion (which would require the leading point to be ≥ tvl – 2 cm = +7 cm). Here, point C is at +4 cm, which is beyond the hymen (> +1) but < +7 cm (tvl – 2 = 9 – 2 = 7). Stage IV requires C ≥ +7 cm. Stage II is between –1 and +1 cm. Stage I is > –1 cm but not meeting Stage II threshold.
