Ultrasound Salpingography In The Diagnosis Of Tubal Patency And Its Effect On Natural Pregnancy

Objective to investigate the value of 4D-HyCoSy in diagnosis of fallopian tube patency and to investigate the factors influencing pregnancy rate after 4D HyCoSy examination.Methods experiment 1: Collect the clinical data of 30 cases of female infertility who underwent laparoscopic sacrocolpopexy(LSC)from September 2017 to December 2018 in the Ultrasound Department of Affiliated Hospital of Inner Mongolia Medical University and within 30 days after examination.The results of contrast-enhanced ultrasound were compared with those of gold standard LSC,and the clinical value of 4D-Hy Co Sy was discussed.Experiment 2: 100 infertile patients with 4D-Hy Co Sy in the Ultrasound Department of Affiliated Hospital of Inner Mongolia Medical University from December 2016 to December 2018 were collected.The activity of bilateral ovaries and the resistance of injecting contrast medium were evaluated during the examination,and the natural pregnancy and the pregnancy time within 12 months after the follow-up examination were followed up.Results Experiment 1: Statistical results: Sensitivity: 93.9%,specificity: 90.5%,false positive rate: 9.5%,false negative rate 6.1%,positive predictive value 93.9%,negative predictive value 90.5%,Kappa analysis showed that the kappa value was 0.844,indicating that 4D-Hy CoSy has a high consistency with the gold standard LSC.To prove the reliability of 4D-HyCoSy in the diagnosis of fallopian tube patency.Experiments 2: 1.The total number of natural pregnancies in 12 months after 4D-HyCoSy examination in 100 infertile patients was 38,which proved that the passage of contrast agents would destroy the micro-adhesion in the pipeline,thereby improving the natural pregnancy opportunities of infertile couples.PR in the first month was significantly higher than that in other observation months.2.According to the results of 4D-HyCoSy,100 women were divided into three groups: 62 cases of type I(bilateral tubal patency),24 cases of type II(unilateral tubal patency and unilateral tubal obstruction),and 14 cases of type III(bilateral tubal obstruction).The pregnancy rate curves of type I,II and III had statistical difference(P < 0.05).3.According to the activity of bilateral ovaries,they were divided into three groups: 76 women with good bilateral ovarian activity,6 women with good unilateral ovarian activity and 18 women with poor bilateral ovarian activity.P = 0.049,which proves that the pregnancy rate curve of different ovarian activity groups has statistical difference.4.According to whether there is resistance in contrast medium injection,60 cases in non-resistance group and 40 cases in non-resistance group(P=0.041),the pregnancy rate curve of contrast medium injection with resistance group and non-resistance group has statistical difference.Conclusion(1)4D-HyCoSy examination and LSC had high diagnostic consistency.It can be widely used in the evaluation of fallopian tube patency;(2)4D-HyCoSy examination can increase the probability of natural pregnancy in infertility patients;(3)There are many factors affecting natural pregnancy after 4D-HyCoSy examination in infertility patients.This experiment concludes that the time after examination,the results of 4D-HyCoSy,ovarian mobility and resistance of contrast medium injection are positively correlated with natural pregnancy.
