Sonohysterogram/Saline Infusion Sonogram or an SIS is a common office based procedure performed at Dallas IVF.
SIS allows our physicians to view the uterine cavity. During the transvaginal ultrasound, sterile saline is inserted through the cervix and into the uterus through a narrow tube. This well tolerated procedure allows the physician to see the walls of the uterus and evaluate for the presence of intrauterine growths such as polyps or fibroids. Additionally, a SIS is an excellent screening study to determine the location of fibroids and their relationship to the uterine cavity.
