子宫输卵管超声造影术对于临床诊断输卵管堵塞所致不孕症的研究进展

不孕症(infertility)是育龄妇女的常见疾病之一，我国育龄妇女不孕症发病率为7%～10%。输卵管疾病导致的不孕症占女性不孕症的30%～50%。因此，评估输卵管通畅性对不孕症的病因诊断十分重要。子宫输卵管超声造影术(HyCoSy)是在超声监测下，实时观察造影剂通过宫腔、输卵管的情况及进入盆腔后的分布情况，对输卵管通畅性进行诊断。HyCoSy具有安全、操作简便、费用低等优势，成为近年快速发展的临床诊断输卵管堵塞所致不孕症的新技术。近年新型造影剂及三维、四维超声实时显像技术应用于HyCoSy，提高了HyCoSy对输卵管通畅性诊断的准确率。笔者拟就HyCoSy对于临床诊断输卵管堵塞所致不孕症的研究进展，尤其是新型造影剂及三维、四维超声技术，应用于临床诊断输卵管堵塞所致不孕症的研究进展进行综述如下，旨在推广HyCoSy在输卵管堵塞所致不孕症中的应用。

Research progress of hysterosalpingo-contrast sonography in clinical diagnosis of infertility due to tubal blockage

Infertility is one of the common diseases in women of childbearing age. In China, The incidence of infertility in women of childbearing age is 7% to 10%. Infertility due to tubal diseases accounts for 30% to 50% in female infertility. Therefore, it is very important to evaluate the tubal patency in the diagnosis of infertility. Hysterosalpingo-contrast sonography (HyCoSy) is a technique for diagnosis of tubal patency by observing contrast agent flowing through the uterine cavity, fallopian tube lumen and pelvic cavity, which is monitored by ultrasound. HyCoSy which is safe, convenient and low cost is rapidly developed and becomes a new technique for diagnosing infertility due to tubal blockage in recent years. With the use of the new contrast agent, real time three-dimensional and four-dimensional ultrasound in HyCoSy, the diagnostic accuracy of HyCoSy in the diagnosis of tubal patency is improved in recent years. This research will focus on the research progress of HyCoSy in clinical diagnosis of infertility due to tubal blockage, especially the new contrast agent, three-dimensional and four-dimensional ultrasound in the diagnosis of infertility due to tubal blockage, in order to generalize the application of HyCoSy in infertility due to tubal blockage.
