An interventional study of Ultrasonography, Pelvic in Uterine Anteflexion, sponsored by University Hospital, Brest. Not yet recruiting at 1 site in France. Open to female participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-03.

The goal of this clinical trial is to evaluate how bladder filling affects the uterine flexion angle in adult nulliparous women with a uterine flexion angle \<90° when the bladder is empty.
The main questions it aims to answer are:
How does the uterine flexion angle change as bladder volume increases? What bladder volume is needed to obtain a uterine flexion angle >90°?
Participants will:
Drink 600 mL of water following a standardized protocol. Undergo repeated suprapubic ultrasound measurements of bladder volume and uterine flexion angle.
Remain under observation until urination or for a maximum of 4 hours. No comparison group is included in this study.
Exclusion Criteria:
Repeated ultrasound measurements, alternating between volume and angle of flexion, immediately following a hydration protocol and then bladder emptying.
Procedure: Ultrasonography, Pelvic
Repeated ultrasound measurements, alternating between volume and angle of flexion, immediately following a hydration protocol and then bladder emptying.
Uterine Flexion Angle Measured at Different Bladder Volumes in Nulliparous Women With an Anteverted Uterus and Baseline Uterine Flexion Angle <90°
The relationship between bladder volume and the angle of uterine flexion, as determined from repeated ultrasound measurements in the participants.
Time frame: 4 hours
