Correlation between anterior compartment prolapse assessments by transperineal ultrasonography and pelvic organ prolapse quantification

Abstract

Objective To explore the clinical value of sonographic quantification of anterior compartment organ prolapse by observing the anterior compartment of postpartum women by transperineal ultrasonography,and to compare the sonogrpahic findings against the pelvic organ prolapse quantification (POP-Q).Methods Transperineal ultrasonography was performed in 67 postpartum primiparae who were diagnosed to have anterior compartment organ prolapse according to POP-Q examination.Taking a horizontal line at the inferior margin of symphysis pubis as reference,the movements of urethra and posterior wall of urinary bladder when patients performing maximum Valsa[va maneuver were studied,and the distance from the lowest point of the posterior wall of urinary bladder to the reference line was measured.The sonographic findings were compared against that of the POP-Q assessment.Results Transperineal ultrasonographic assessment of anterior compartment organ prolapse showed great correlation to POP-Q examination (r =0.70).The criteria of anterior compartment organ prolapsed evaluation by transperineal ultrasonography were:1) When the maxima[descent of the posterior wall of urinary bladder was still above the reference line,it was defined as I-degree;2) If the lowest point of the posterior wall fell below the reference line but still less than 2 cm,it was defined as Ⅱ degree.Conclusions Transperineal ultrasonography can be used to evaluate anterior compartment organ prolapse and it has high correlation to POP-Q examination.Transperineal ultrasonography is a more objective method of quantification of anterior compartment organ prolapse in clinical practice.
