INTRODUCTION AND HYPOTHESIS: the study aims were to evaluate (1) the interobserver and (2) the interdisciplinary repeatability of levator hiatus, urethral thickness, and anorectal angle measurements using three-dimensional endovaginal ultrasound (3D-EVUS). METHODS: twenty-seven nulliparous asymptomatic females were imaged with 3D-EVUS. Analyses were conducted off-line from stored 3D volumes by six readers (two radiologists, two urogynecologists, and two colorectal surgeons) using a standardized technique. Reproducibility was determined using the interclass correlation coefficients (ICC). RESULTS: the overall interobserver repeatability for levator hiatus dimensions was good to excellent (ICC, 0.655-0.889), for urethral thickness was good (ICC, 0.624), and for anorectal angle was moderate (ICC, 0472). The interdisciplinary repeatability for levator hiatus indices was good to excellent (ICC, 0.639-0.915), for urethral thickness was moderate to good (ICC, 0.565-0.671), and for anorectal angle was fair to moderate (ICC, 0.204-0.434). CONCLUSIONS: 3D-EVUS yields reproducible measurements of levator hiatus dimensions and urethral thickness in asymptomatic nulliparous women.
