Chapter 25 - Ultrasonography and hydrosalpinges in IVF

Summary

This chapter discusses the usefulness of ultrasound in diagnosing normal and abnormal fallopian tubes using two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasonography (TVS) and hysterosalpingo-contrast sonography (HyCoSy). HyCoSy involves the introduction of fluid into the uterine cavity and the fallopian tubes. The role of HyCoSy as a first-line procedure for the assessment of tubal patency has been examined in several studies. In most of the studies, the diagnostic capabilities of HyCoSy have been compared with the established reference methods of hysterosalpingography (HSG) or laparoscopy with dye insufflation, or both, and in the majority of the studies Echovist was used as the ultrasonographic contrast medium. A multicenter study in Scandinavia compared laparoscopic salpingectomy with no intervention prior to the first in vitro fertilization (IVF) cycle. The study demonstrated significant improvement in pregnancy and birth rates after salpingectomy in patients with hydrosalpinges that were large enough to be visible on ultrasound.
