Ultrasonography reappraisal of tubal patency in assisted reproduction technology patients: Comparison between 2D and 3D-sonohysterosalpingography. A pilot study
BacKGroUND: The aim of this study was to compare 2D and 3D-sonohysterosalpingography (2D-3D-HyFoSy) with previous diagnostic laparoscopy in the diagnosis of tubal patency, and compare each procedure in terms of procedure’s time, perceived pain and complication rate. MeTHoDS: We prospectively recruited infertile women, previously submitted to laparoscopy and randomly allocated into 2D-HyFoSy (group I) and 3D-HyFoSy (group II).
