Background: Chronic pelvic pain is a common complaint in the
gynecological office. The association among anus levator muscle injury, CPP of
unknown origin in parous women, and pelvic sensory symptoms have been
demonstrated. The study’s purpose is to
assess the intrarater/interrater reliability and agreement of pelvic floor biometry and levator ani muscle injury evaluated using three-dimensional ultrasound in women with chronic pelvic pain.
Methods: Two raters independently and blindly acquired three datasets of three-dimensional transperineal ultrasound volumes. The datasets were evaluated 60 days apart. To assess levator ani muscle injury, the hiatal area/diameter, levator ani muscle thickness, urethra-anus distance, and levator-urethra gap
were measured. The intrarater reproducibility and interrater reproducibility were calculated. The concordance correlation coefficients and limits of agreement were analyzed in 147 three-dimensional ultrasound volumes obtained from 49 patients.
Results: Levator ani muscle injury was detected in 10.2% (n = 5/49), with a good intrarater concordance correlation of
