About this study
Official title: Prospective Self-controlled Study for Shortening the Time Before Taking Delayed Radiographs With Iodized Oil Hysterosalpingography
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

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Add 4-hour delayed radiographsDiagnostic test
Normal patients only need to take delayed radiographs 24h after HSG operation. In this study, 4-hour delayed radiographs were added to the 24-hour delayed radiographs, so that the patients had to take one more delayed radiographs .
| Study group | Role | What they receive |
|---|---|---|
| 4-hour delayed radiographs | Other | The follow-up radiographs was taken 4 h after the HSG operation. Receives: Diagnostic Test: Add 4-hour delayed radiographs |
What is being measured
The primary outcome is the main question the study is designed to answer.
Difference in diagnosis of fallopian tube patency between 4 hours delayed radiographs and 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.
Measured: The evaluation was performed within 1 day after completion of the 24 hours delayed radiographs.
Secondary outcomes (3)

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.
