摘要

Objective: To investigate the feasibility of transperineal ultrasound in quantitative assessment of posterior compartment prolapse among Chinese women. Methods: The prospective multicenter study enrolled 485 women between January 2017 and January 2019. All patients underwent a standard clinical interview, pelvic organ prolapse quantification (POP-Q) examination and transperineal ultrasound examination. Volume data of transperineal ultrasound examinations were obtained at rest and in maximal Valsalva maneuver. Results: The higher POP-Q stage of posterior compartment, the lower rectal ampulla position in maximal Valsalva maneuver (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥2, P<0.001), and the greater rectal ampulla hypermobility (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥ 2, P=0.007). The rectal ampulla position at rest and in maximal Valsalva maneuver and rectocele depth were correlated with prolapse symptoms (r=-0.200, P<0.001; r=-0.252, P<0.001; r=0.086, P=0.045). The corresponding cut-off values of rectal ampulla position in maximal Valsalva in diagnosing posterior compartment prolapse (POP-Q stage ≥1) and clinical significant posterior compartment prolapse (POP-Q stage ≥2) were 7.32 mm below the symphysis pubis and 12 mm below the symphysis pubis, respectively, with the area under the ROC curve as 0.75 and 0.85, respectively. Conclusions: The ultrasonic measurements by transperineal ultrasound is significantly associated with POP-Q examination in posterior compartment, and it is demonstrated as a useful tool in quantitative assessment of the severity of posterior compartment prolapse.
