How many times of hydrotubation is appropriate for the symptoms of fallopian tube obstruction?

Fallopian tube obstruction is a common clinical disease. This disease has a great impact on people's bodies. The symptoms of fallopian tube obstruction are very obvious. Hydrotubation is also one of the treatments for fallopian tube obstruction. The specific number of hydrotubations should be determined based on the patient's actual physical condition.

1. The specific number of times the fallopian tube hydrotubation is performed depends on the individual's physical condition. A tube is passed into the uterine cavity of the person being examined, and then 20 ml of medicine is injected through the tube. The medicine is usually saline plus antibiotics (usually gentamicin). The medicine flows from the uterine cavity through the fallopian tubes and finally reaches the pelvic cavity. According to the characteristic that the uterine cavity can only hold 5ml of volume, if the entire 20ml of solution can be pushed in smoothly without resistance, and no liquid flows back into the syringe after releasing the needle, it indicates that the solution has passed through the uterine cavity and fallopian tube cavity into the abdominal cavity, indicating that the fallopian tube is unobstructed; if the resistance is very large, and more than 10ml of solution flows back into the syringe after releasing the needle, it indicates that the fallopian tube is blocked; if most of the liquid can still be injected despite resistance, and only a small amount flows back, it indicates that the fallopian tube is unobstructed.

2. Different patients have different tolerance levels to pain, so it is impossible to determine whether the fallopian tubes are unobstructed based on the patient's feelings, resulting in a large number of false negative and false positive diagnostic results. For example, when hydrosalpinx occurs, the liquid enters the hydrosalpinx cavity. Although 20 ml can be injected smoothly, the fallopian tube is actually blocked. It is also impossible to accurately determine whether the fallopian tube is blocked on one side (patent) or on both sides, nor can it be determined specifically where the blockage is. The patient's nervousness during the examination will also affect the results of the examination. During examination, many patients experience muscle tension that causes spasm of the fallopian tubes, which prevents the injection of the medicine. The doctor may feel the resistance to the injection and make a diagnosis of false obstruction. Therefore, it is unreliable to use the method of hydrotubation to judge the patency of the fallopian tube.

3. Hydrotubation is not a very good method to treat fallopian tubes. Hydrotubation is only effective for mild adhesions. If the adhesion is mild, angiography can flush it out. If angiography cannot clear it out, hydrotubation will have no effect. Moreover, repeated hydrotubation is harmful to the fallopian tubes. First, repeated hydrotubation may destroy the fallopian tube's own peristalsis and the cilia's swinging ability. Secondly, every time a hydrotubation is performed, the chance of infection increases, especially if the disinfection is not strict. Many cases where the fallopian tubes were not seriously injured originally may become worse after a hydrotubation.
