Hysterosalpingo-foam sonography (HyFoSy): a new technique to visualize tubal patency.

摘要

Assessment of Fallopian-tube patency is an important part of routine infertility work-up, as tubal obstruction is estimated to play a role in 12-33% of infertile couples1'2. Several tests are available for this .purpose, including hys-terosalpingography, laparoscopy and dye test, selective salpingography and hysterosalpingo-contrast sonography (HyCoSy). HyCoSy allows assessment of the outline of the uterine cavity and patency of the Fallopian tubes. It can be performed with standard transvaginal ultra-sonography equipment.
