Saline Infusion Ultrasound
Saline infusion ultrasound (SIU) is a diagnostic procedure that involves the infusion of sterile saline solution into the uterus while performing an ultrasound examination. It is also known as sonohysterography or saline sonogram. This procedure allows for a detailed evaluation of the uterine cavity and can help identify abnormalities or structural issues that may be causing symptoms or fertility problems.
Here is an overview of the saline infusion ultrasound procedure:
- You will typically lie on an examination table with your feet in stirrups, similar to a pelvic exam.
- A speculum will be gently inserted into the vagina to visualize the cervix.
- A small, flexible catheter is then inserted through the cervix and into the uterine cavity. The catheter is used to deliver the sterile saline solution into the uterus.
- Your doctor will slowly and steadily inject the saline solution into the uterus while monitoring the process using ultrasound imaging. The saline helps to expand the uterine cavity, providing a clearer view of the uterine lining and any potential abnormalities.
- A transvaginal ultrasound probe will be used to examine the uterine cavity. The ultrasound images obtained during the saline infusion can help identify abnormalities such as uterine polyps, fibroids, adhesions, or abnormalities of the uterine lining.
- Once the examination is complete, the catheter is removed, and you may be able to empty your bladder. You can usually resume normal activities after the procedure, although you may experience some mild cramping or spotting.
Saline infusion sonogram is generally a well-tolerated procedure, but it is common to experience some discomfort or cramping during the infusion of saline.
