Saline Infusion Sonohysterography (SIS)

Author: Dr Monica Pahuja*

What are the prerequisites for having a SIS done?

There are no prerequisites. It is a good test to assess the endometrium for those patients who have persistent endometrial thickening, suspicion of polyps, and assessment of post menopausal endometrium, patients taking tamoxifen, or those with possible Asherman’s Syndrome.

What are the absolute contraindications for a SIS?

  • Pregnancy
  • Concurrent PID

What are the relative contraindications for a SIS?

  • Possible PID or vaginal discharge
  • Menstruating
  • Cervical stenosis (inability to introduce catheter into uterine cavity)

What are the adverse effects of a SIS?

There is a very small risk of endometrial infection post procedure.

Are there alternative imaging tests, interventions or surgical procedures to a SIS?

Hysteroscopy and dilatation and curettage may provide similar and/or complementary information to SIS. The examination should be scheduled day 2-3 after the last period.
