Sono-HSG fallopian tube patency test (SIS, salpingohydrosonography, HyCoSy)
Standard pelvic ultrasound does not allow for an accurate assessment of the uterine cavity or the patency of the fallopian tubes. Several different diagnostic techniques are available to examine uterine patency and exclude blocked tubes properly. The least invasive one is Sono-HSG. It assesses the size and shape of the uterine cavity and the patency of the fallopian tubes. Adhesions, polyps, submucosal myomas, and some congenital anomalies of the uterus can be detected.
