Volløyhaug I, et al. - Authors ascertained if there was any association between pelvic organ prolapse quantification (POP-Q) and ultrasound measurement of prolapse in women from a normal population. They also identified which method had a stronger association with prolapse symptoms. Findings suggested moderate to strong correlation of POP-Q and ultrasound measurement of prolapse in the anterior and middle compartments and weak correlation in the posterior compartment. They noted a strong association of both methods with the symptom “vaginal bulge,” however, the association with POP-Q was stronger than that of ultrasound.
