Abstract: ［Abstract］ Objective〖HTSS〗〓To refine the classification of the patency degree of fallopian tube on hysterosalpingography and to explore the types of the patency degree, because that the patency degree of fallopian tube is the important influence factor in infertility.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓We analyzed 93 cases of infertility patients, drew up the hierarchical quantification standard of patency degree in fallopian tube (hereinafter referred to as test standard) and studied the consistency of different doctors or former and later diagnosis results of the doctor to evaluate the classification standard. In addition, we also observed the retention sign of contractmedium in fallopian tube on delayed photography after 15 minutes(hereinafter referred to as delayed period). Compared with filing period of fallopian tube and uterus(hereinafter referred to as filling period), the author explored the types of patency degree in fallopian tube.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The patency of fallopian tube was diagnosed according to the morphology of fallopian tube and the subjective indexes such as the contrast agent flow rate observed by the operator(hereinafter referred to as the original standard). The diagnosis is poorly consistent, whether between the doctor or the doctor themselves. The patency of fallopian tube was measured by standard test, and the Kappa value was 1.000 among different doctors. There were no significant differences in the patency of fallopian tubes between the two groups during the prolonged period.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The patency degree in fallopian tube can be divided into four grades: patency, patency but not free, tiny patency and occlusion. The patency degree in fallopian tube can be divided into two types, mechanical patency degree and functional patency degree. The internal relation between form and function is the key point for further study.
