What tests are needed if all fallopian tubes are blocked?

The health of the human body is actually closely related to the health of each organ in the body. Take the fallopian tube, an important reproductive organ in the female body, for example. Once it is damaged or suffers from some diseases, it may affect the female's physical health, or at least her fertility. The most common disease is blocked fallopian tubes. So, what tests do people with completely blocked fallopian tubes need?

1. Hydrotubation. Hydrotubation is a procedure in which a tube is inserted into the uterine cavity of the person being examined, and 20 ml of a solution is injected through the tube. The solution is usually normal saline plus antibiotics. 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 be injected despite resistance, and only a small amount flows back, it indicates that the fallopian tube is unobstructed.

2. Ultrasonic examination. Ultrasound examination of the fallopian tubes includes conventional ultrasound examination and ultrasound-assisted fluid intubation. During routine examinations, some hydrosalpinx can be detected on ultrasound, showing as thickened liquid dark areas on both sides of the uterus. However, ultrasound cannot confirm whether it is hydrosalpinx or ovarian cyst. It can only be diagnosed as: indicating the possibility of hydrosalpinx.

3. Hysterosalpingography by X-ray. X-ray hysterosalpingography can show the size, shape and position of the uterine cavity and the shape of the fallopian tubes on the fluorescent screen and X-ray images. If the fallopian tube is unobstructed, the image extends beyond the fimbria of the fallopian tube, and the diffusion of contrast agent in the pelvic cavity can be seen on the X-ray film at the same time. If the fallopian tube is blocked, the location, degree and nature of the blockage can be clearly shown.

4. Laparoscopic examination. Inject a pigment liquid such as methylene blue into the uterine cavity through the uterine catheter. Observe through laparoscopy that the methylene blue overflows from the fimbria of the fallopian tube into the pelvic cavity, which means the fallopian tube is unobstructed. If the proximal fallopian tube is blocked, the methylene blue fluid will not overflow from the fimbria of the fallopian tube into the abdominal cavity. If the distal fallopian tube is blocked, the fimbria of the fallopian tube and the ampulla of the fallopian tube can be seen to be expanded, thickened and stained blue, but there is no methylene blue fluid flowing from the fimbria of the fallopian tube into the abdominal cavity.
