Abstract：About 25%-35% of female infertility are involved in tubal factors. The examination of oviduct patency is a clinical routine for the diagnosis of female infertility. The diagnostic techniques by ultrasonic tomography include: hysterosalpingography (HSG), laparoscopy with chromotubation (LC), transvaginal sonography (TVS), saline-infusion sonography (SIS) and 4-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy). HSG is widely used with relatively high accurate diagnosis but also high false positive rate, and X-Ray exposure. Although LC was considered as a "gold standard", LC is a invasive and expensive diagnosis. TVS and SIS have been rarely used because of their limited value in diagnosis. The 4D-HyCoSy not only enjoys accuracy and convenience, but also avoids risks like iodine allergy, radiation and pulmonary embolism.
