Normal uterus and uterine malformations.

The uterus is well visualized with sonography with the definition of its morphofunctional characteristics and the physiologic variations in relation to hormonal stimuli. With high frequency endovaginal and intrarectal probes, anatomical details are optimal. Color Doppler enables the study of blood flow in the pelvic vessels and supplies functional information. Hysterosalpingography is the most accurate method for the study of the uterine cavity and the evaluation of tubal patency. In the study of uterine malformations, sonography represents the procedure of first choice, able to diagnose anomalies of fusion and development of müllerian ducts. In cases of dubious or ascertained malformations, hysterosalpingography is mandatory to complete the sonographic findings.
