The Sion test

Endosonography as a tool for checking the patency of Fallopian tubes was an expected development in the progress the field of gynaecology was taking. We at Sion Hospital have used transvaginal sonography in evaluating the patency of Fallopian tubes with a technique which encompasses a thorough pelvic scan as well. We offer The Sion Test not as a substitute for hysterosalpingography, laparoscopy or hysteroscopy but as a screening technique in infertility investigation. The Sion Test can be performed in the gynaecologists' office at the same time as the pelvic examination. A series of 50 infertile patients had a diagnostic laparoscopy and hysterosalpingography after our test was done. We have compared the accuracy of the 3 methods of evaluating tubal patency and have found our test an excellent screening technique for investigations in infertility.
