This is a procedure to assess your uterine cavity and the patency of your fallopian tubes. It uses ultrasound and sterile saline rather than ionizing radiation (x-rays) and x-ray dye.
The procedure is usually performed days 5 to 10 of your cycle, immediately after your last menstrual period, or as advised by your specialist. Please allow an hour for the procedure.
What does SIS involve?
Firstly, a routine ultrasound of your uterus and ovaries is performed by the ultrasound technician.
A speculum is placed by the doctor or a trained technician (similar to having a cervical smear test) and a thin catheter (tube) is then gently passed through the cervix into your uterus. The speculum is removed and the vaginal ultrasound probe is re-introduced and saline (fluid) is injected through the catheter into the uterus. This outlines the uterine cavity and demonstrates the fallopian tubes. Once these have been demonstrated, the ultrasound probe and catheter are removed.
The speculum examination is occasionally uncomfortable. You may experience a cramping sensation as the tube is passed through the cervix and a feeling of distension as the fluid is instilled into the uterus. However, the procedure is not usually painful and we endeavour to make the procedure as comfortable for you as possible.
It is advisable to take some form of analgesia (painkiller), such as Nurofen prior to the procedure and to bring a support person with you.
When making your booking, it is helpful if you can let us know if you have a latex allergy.
What are the possible side effects of SIS?
After your procedure, you may experience some abdominal discomfort and vaginal spotting and it is safe to take analgesia as appropriate.
There is a small risk of infection from the procedure and you will be given a prescription for antibiotics at the end of your examination. If you develop pelvic pain, feel feverish or develop an unpleasant discharge, please consult your doctor.
The results will be discussed with you after the examination and a report will be sent to your referring doctor.
