Ultrasonography, especially 3D, is essential in the diagnosis and preoperative evaluation of gynecologic surgeries and is important in surgical planning and counseling of patients. In addition, it is useful during hysteroscopic procedures, particularly difficult Asherman syndrome cases, resection of transverse vaginal septum, and treatment of hematometria. 3D ultrasound is especially helpful for fibroid mapping as the simultaneous visualization of the endometrium and myometrium with the coronal view is possible, it can be done by the gynecologist and at a lower cost than an magnetic resonance imaging. The ability to visualize with ultrasound during surgery may reduce complications and eliminate the use of laparoscopy.
