Hysteroscopy does not allow direct visualization of the tubes, but indirect observation of the tubes can be used to determine whether the tubes are open or not.
Tubal cannulation is a tube inserted into the uterine cavity of the examinee, if there is resistance to tubal cannulation under the direct view of the hysteroscope, it suggests that the fallopian tube is open, but not smooth; if there is a lot of resistance and reflux, it suggests that the fallopian tube is not smooth on that side. So hysteroscopic surgery is able to see whether the fallopian tube is open or not.
However, if you want to clarify which section of the fallopian tube is blocked, you can have a trans X-ray tubal angiogram on the advice of your doctor, which will show whether the fallopian tube is patent or not directly from the X-ray film. If the tubes are patent, the image can be continued to the outside of the umbilical opening of the fallopian tube; if the fallopian tube is blocked, the location and extent of the blockage can also be seen directly.
If the patient has tubal impermeability, it is recommended to consult a doctor in time, under the guidance of the doctor to carry out appropriate treatment.
