Saline infusion sonohysterography (SIS)

The saline infusion sonohysterography (SIS) procedure is a quick, and minimally invasive procedure which can be performed in the physician’s office with virtually no patient discomfort. SIS provides details of soft tissue structures as well as of the shape of the uterine cavity. This technique allows a detailed study of the uterine cavity in cases of infertility, amenorrhea, uterine anomalies and inadequate or abnormal endometrial images. In the future, SIS performed with ultrasound contrast media may replace HSG evaluation for infertility patients. Also, as the technology advances Sonohysterographic guided biopsy and excision may become possible as well. SIS is easily learned and requires little additional expenses in offices providing ultrasound services. As with any technique, no single procedure can replace our full arsenal of diagnostic choices and the decision to perform SIS must be individualized to patient selection, physician preference and experience.
