ACOG Technology Assessment in Obstetrics and Gynecology No. 5: sonohysterography.

The goal of sonohysterography is to visualize the endometrial cavity in more detail than is possible with routine transvaginal ultrasound. The procedure consists of the manual injection of sterile fluid under real-time ultrasonographic imaging. The most common indication for sonohysterography is abnormal uterine bleeding. The procedure should not be performed in a woman who is pregnant or who could be pregnant, or who has a pelvic infection or unexplained pelvic tenderness. Physicians who perform or supervise diagnostic sonohysterography should be skilled in vaginal ultrasonography and transcervical placement of catheters; should have training, experience, and demonstrated competence in gynecologic ultrasonography and sonohysterography; and should keep careful records.
