Intracavitary and submucosal leiomyomas (fibroids). Using saline-infusion sonohysterography, we can determine the location and intracavitary extent of leiomyomas. The intracavity proportion of leiomyomas is commonly used to determine whether hysteroscopic resection is likely to be successful. Saline-infusion sonohysterography involves inserting a small tube into the uterus. Then a transvaginal ultrasound is performed as a small amount of saline saline is placed within the uterine cavity. The saline allows the location of the fibroids to be seen more precisely.
Endometrial polyps. Using saline-infusion sonohysterography (SIS), we can diagnose endometrial polyps accurately and easily. Like for fibroids, SIS can be used to see endometrial polyps inside the uterus. The saline in the uterus will outline the polyps, making their presence very clear.
