Saline Infusion Sonography (SIS)
Saline Infusion Sonography (SIS) is a specialised ultrasound technique used to assess the uterine cavity for abnormalities. This procedure is particularly helpful in identifying issues such as endometrial polyps, fibroids, adhesions, or scar tissue that may affect menstrual health, fertility, or cause recurrent miscarriages. SIS is often recommended as part of infertility assessments or follow-up after uterine surgeries.

The SIS scan is recommended for individuals with abnormal or irregular uterine bleeding, those experiencing recurrent miscarriages, or individuals struggling with fertility issues. It is also useful for evaluating the uterine cavity after surgeries like fibroid removal or polypectomy.
FAQs
During the SIS scan, a speculum is inserted into the vagina to access the cervix. A small catheter is then gently passed through the cervix into the uterus, where saline solution is infused to expand the uterine cavity. A 3D ultrasound scan is then performed to capture detailed images of the uterine lining.
The SIS scan may cause mild discomfort, particularly during the insertion of the catheter into the cervix. However, most patients find the procedure to be manageable, with any discomfort subsiding quickly after the scan.
After the SIS scan, you may experience mild discomfort or feel wet due to the saline used. Some patients may also have light spotting or cramping, but these symptoms typically resolve quickly. To reduce the risk of infection, prophylactic antibiotics are given, and you may be advised to rest after the procedure.
