Retrof Thelexed Uterus

Description

Uterus in retroflexion is centered in a midline pelvic orientation where the fundus and corpus uteri angle posteriorly at the uterine isthmus while the cervix remains directed toward the vaginal canal. The anterior surface of the uterine body faces away from the urinary bladder, and the posterior uterine wall approaches the rectum across the peritoneal reflection of the rectouterine pouch (pouch of Douglas). Superiorly, the fundal contour is continuous with the uterine horns, and inferiorly the narrowing isthmus transitions into the cervix, the fixed point around which the posterior curvature is most apparent. A fixed, posterior curve. Retroflection matters because it changes the relationship between the uterus, bladder, and rectum, which can influence both symptoms and procedural access. Patients with a retroflexed uterus may report deep dyspareunia or pelvic pressure, and the position can complicate intrauterine device placement or endometrial sampling when the uterine sound must follow a posteriorly directed uterine cavity rather than the more common anteverted trajectory. This perspective is also a practical teaching reference for correlating pelvic examination findings with sonographic descriptions, where retroflexion is often documented separately from version (anteversion or retroversion) of the cervix. Clinicians often anchor the concept at the isthmus because it is the hinge point for flexion and a consistent landmark during bimanual exam. Use this illustration in pelvic anatomy modules for medical and midwifery training, and in gynecology texts discussing uterine position, uterine sounding technique, or common reasons for difficult cervical canal instrumentation. It also fits patient education materials explaining normal anatomic variation and how uterine orientation is reported in ultrasound or operative notes.
