Having a transvaginal ultrasound completed before your SIS procedure is important for many reasons. A transvaginal ultrasound can allow us to identify why you may be experiencing tenderness in your uterus and whether any antibiotics would be required before the procedure. If active pelvic inflammatory disease is found, your exam may be rescheduled for a date after you take antibiotics to avoid exacerbating the infection or seeding it in the pelvis.  Pre-procedure ultrasounds are also useful screening tools for uterine or ovarian conditions. They can also be used to discover the size and position of the uterus and orientation of the cervix, which may influence how the speculum and catheter are placed during your SIS.  Ideally, pre-procedure imaging should be performed by the same person performing the SIS. Our highly qualified technologists and radiologists have years of experience in interpreting ultrasounds and SIS results, which can make the difference in a more comfortable procedure, as well as accurate, efficient detection and diagnosis of conditions.
