Abstract: Tubal Patency tests include procedures like hydrotubation, hysterosalpingography (HSG), hystero-salpingo contrast sonography (HyCoSy) and laparoscopic hydrotubation. Hydrotubation is seldomly undertaken due to its invisibility. HSG is the first choice of tubal patency test, which evaluates tubal patency based on the distribution of lipiodol contrast. Adverse contrast reactions and radiation injury may occur. As the "gold standard" for tubal patency test, laparoscopic hydrotubation is not our preferred choice due to expensiveness. In recent years, HyCoSy has become a research hotspot because of its real-time dynamic, visualization, radiationless and other advantages. With the development of ultrasound contrast agents and the application of low-pressure injection pump and pressure monitor, HyCoSy is expected to surpass HSG and become the preferred method for tubal patency test.
