Changes in the Angle of Uterine Flexion as the Bladder Fills

Condition(s) studied

Investigational drug(s) / intervention(s)

Ultrasonography, Pelvic: Repeated ultrasound measurements, alternating between volume and angle of flexion, immediately following a hydration protocol and then bladder emptying.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Uterine Flexion Angle Measured at Different Bladder Volumes in Nulliparous Women With an Anteverted Uterus and Baseline Uterine Flexion Angle <90° — 4 hours
  The relationship between bladder volume and the angle of uterine flexion, as determined from repeated ultrasound measurements in the participants.
