Abstract: After Essure (Bayer AG, Leverkusen, Germany) hysteroscopic sterilization procedure, a confirmation test is performed to assess the success of sterilization with evaluation of the micro-insert position or tubal occlusion. The imaging techniques used for ascertaining the correct microinsert position or tubal occlusion may vary among countries and include hysterosalpingography (HSG), sonography, plain pelvic radiography, and hysterosonography. However, HSG remains reference standard. Non-HSG techniques are preferred because HSG is an invasive procedure that exposes the patient to ionizing radiation, is uncomfortable for the patient, and can be associated with adverse effects. Recently, hysterosalpingo-foam sonography (HyFoSy) was introduced and was suggested to be a possible less invasive alternative to HSG. Our prospective study included patients, who underwent Essure hysteroscopic sterilization, followed by 2D transvaginal ultrasonography, HyFoSy and HSG 12 weeks after sterilization. The purpose of our study was to evaluate the accuracy of 2D tranvaginal ultrasonography and HyFoSy compared to HSG for assessment of the efficacy of Essure hysteroscopic sterilization.
