A saline infusion transvaginal ultrasound (SIS) is a special procedure using a different technique of sonography. Advanced Minimally Invasive Gynecology is one of the few practices in the Central Florida region that offers SIS.

First, you will be asked to empty your bladder. This is an office procedure that starts with a transvaginal ultrasound. The addition of saline infusion to a conventional ultrasound is done for women with a suspected abnormality of the uterine cavity (the inside of the uterus). It is most commonly done in women with abnormal vaginal bleeding. This procedure lasts approximately 20 minutes.
For this procedure, the provider uses a ‘transvaginal probe’ which is an elongated narrow device that is placed in the vagina.  This device uses sound waves to image the organs in your pelvis.  The probe is then removed and the doctor will place a speculum in the vagina to visualize the cervix (the opening of the uterus).  The cervix is cleaned with a disinfectant and a small catheter is inserted in the uterus.   The speculum is then removed and the ultrasound probe is put back in the vagina.   A small amount of sterile fluid is inserted into the uterus through the catheter; this is done as the ultrasound probe images your uterus.  The fluid helps provide better images of the cavity and lining of the uterus than a conventional transvaginal ultrasound.  Once the images are stored in the computer and analyzed by your provider, the catheter and probe are removed from the vagina.  At the end of your procedure, the doctor will tell you the results and discuss what you should do next in your therapy.
You may experience some cramping or spotting during or after this procedure.  Most women do not need any additional pain relief to have this procedure but it always helps if you take some ibuprofen before and after your procedure
