Prospective Study of the Variation in the Angle of Anteflexion of the Uterus Before and After Micturition in Nulliparous Women With Uterine Anteversion.

A monocentric, prospective, comparative, and descriptive clinical study examining the uterine anteflexion angle before and after bladder emptying in nulliparous women with uterine anteversion. The study aims to assess how bladder fullness affects the anteflexion angle, which may impact the ease of intrauterine device (IUD) insertion. The primary objective is to determine the variation in the angle of anteflexion of the uterus before and after micturition in nulliparous women with uterine anteversion. Ultrasound measurements will be taken before and after bladder emptying. A secondary objective is to determine the prevalence of uterine anteversion in nulliparous women.
