Objective: We aimed to compare the morphological characteristics of pelvis and urethra in nulliparous pregnant women with and without stress urinary incontinence (SUI) by 3D high-frequency endovaginal ultrasound (3D-EVUS).
Study Design: At 36-38 weeks of gestation, 40 nulliparous pregnant women with and without SUI underwent 3D-EVUS assessment. The anteroposterior and transverse diameters of levator hiatus (LH), pubovisceral muscle thicknesses at 3,9 and 12 o'clock, right and left paravaginal areas, symphysis angle, bladder-symphysis distance (BSD), uretral complex thickness (Ut), urethral complex width (Uw), urethral complex volume (UV), urethral length (UL), intramural urethra, rhabdosphincter thickness (Rt), rhabdosphincter width (Rw), rhabdosphincter length (RL), and rhabdosphincter volume (RV) were measured by 3D-EVUS.
