Abstract:
Objective:To investigate the association between levator hiatus area, pelvic organ prolapse quantification (POP-Q) examination and prolapse symptoms.Methods:The prospective multicenter study enrolled 996 female patients between January 2017 and January 2019. All enrolled patients underwent a standard clinical interview, POP-Q examination and transperineal ultrasound examination. Volume data of pelvic floor ultrasound examinations were obtained at rest, during contraction and during maximal Valsalva maneuver. The association between levator hiatus area, POP-Q examination and prolapse symptoms was analyzed. The performance of levator hiatus area on maximal Valsalva for assessing significant POP(POP-Q stage≥2) and prolapse symptoms were also evaluated.Results:There were significant differences of levator hiatus area at rest, during contraction and during maximal Valsalva among patients with different POP-Q stages (all P<0.001). Levator hiatus area during maximal Valsalva showed the highest correlation with abdominal dragging sensation ( r=0.277, P<0.001). The area under the ROC curve (AUC) of levator hiatus area during maximal Valsalva for significant POP (POP-Q stage≥2) was significantly higher than that for prolapse symptoms (AUC: 0.77 vs 0.69, P<0.001). Conclusions:Levator hiatus area on transperineal has moderate correlation with POP-Q examination and their association is stronger than the correlation between ultrasound findings and prolapse symptoms.
