Sonohysterography

Abstract

Sonohysterography (SHG) is a simple, less invasive, and inexpensive technique using the transcervical injection of sterile fluid during ultrasonic examination. As SHG is very helpful for the diagnosis of congenital or acquired abnormalities of the uterus and tubal patency, it is indicated in patients with abnormal uterine bleeding, infertility, recurrent pregnancy loss, and so on. The SHG provides better definition of intracavitary lesions, such as endometrial polyp, submucous leiomyoma, and synechiae, than simple transvaginal sonography. Currently, SHG has become a standard test in gynecological outpatient facilities. Adequate training, careful operations, and thoughtful interpretations are required for safe procedure and accurate diagnosis.
