研究概览
简要总结
Background of the study:
Hysterosalpingography (HSG) is widely used for the female infertility workup. Many studies have demonstrated that the use of oil-soluble contrast medium (OSCM) ethiodized oil for HSG surgery can improve pregnancy rates. However,The 24-hour delayed radiographs of OSCM HSG also brought some inconvenience to the patients , for example, patients need to make two trips to the hospital.
Objective of the study:
The purpose of this study was to compare OSCM HSGs using 4-hour and 24-hour delayed radiographs in terms of diagnosing tubal patency and identifying the presence of pelvic adhesions.
Study design:
Prospective, open label, self - controlled study
Study population:
Infertile patients scheduled for an OSCM HSG

研究组 & 干预措施
4-hour delayed radiographs
The follow-up radiographs was taken 4 h after the HSG operation.
干预措施: Add 4-hour delayed radiographs (Diagnostic Test)
结局指标
主要结局
Difference in diagnosis of fallopian tube patency between 4 hours delayed radiographs and 24 hours delayed radiographs.
时间窗: The evaluation was performed within 1 day after completion of the 24 hours delayed radiographs.
The diagnostic results of 4 hours delayed radiographs and 24 hours delayed radiographs were evaluated by two radiologists with more than 5 years' working experience. In case of any dispute, the two doctors reached an agreement after discussion. The results were defined as : completely consistent; mostly consistent;partly consistent;completely different.
次要结局
- Difference in the diagnosis of patency of distal fallopian tube between 4 hours delayed radiographs and 24 hours delayed radiographs(The evaluation was performed within 1 day after completion of the 24 hours delayed radiographs.)
- Difference in the diagnosis of pelvic lesions between 4 hours delayed radiographs and 24 hours delayed radiographs.(The evaluation was performed within 1 day after completion of the 24 hours delayed radiographs.)
- Difference in the diagnosis of patency of proximal fallopian tube between 4 hours delayed radiographs and 24 hours delayed radiographs(The evaluation was performed within 1 day after completion of the 24 hours delayed radiographs.)
