Applicable gender: whether women are fasting: fasting

Analysis results:

Below normal:

Normal value:
no

Above normal:

negative:
There is no blue liquid flowing out of the umbrella end of the fallopian tube, or there is no blue staining nearby.

Positive:
Blue blood flow out of the end of the fallopian tube, or blue staining nearby indicates obstruction of the fallopian tube.

There is no blue liquid flowing out of the umbrella end of the fallopian tube, or there is no blue staining nearby.

Clinical significance

Abnormal results: blue liquid outflow at the umbrella end of the fallopian tube, or blue staining in the vicinity indicates obstruction of the fallopian tube.

People who need to check:

1. Primary or secondary infertility, suspected tubal obstruction.

2. The effect of surgery after tubal ostomy or adhesion separation.

3. After the sterilization of tubal ligation, occlusion, etc., check the surgical results.

4. After the fallopian tube recanalization, the surgical effect is checked and the anastomosis adhesion can be prevented.

5. Treatment of mild fallopian tube obstruction.

Positive results may be diseases: complications after tubal ligation, tubal obstruction infertility, tubal infertility, tubal malformation, hydrosalpinx, fallopian tube obstruction

Taboo before inspection:

1. Fasting for 12 hours.

2. Do not have sex before 3 days.

3. Test at 3d-7d after menstruation is clean.

Requirements for inspection:

1. After the test, the patient was banned from the same room and bathed for 2 weeks.
