Patient's question:
Got married for two or three years without taking any contraceptive measures, but still can't get pregnant. What tests need to be done for blocked fallopian tubes?Doctor's answer:
Methods for checking fallopian tube blockage include:1. Laparoscopic examination: Medication is introduced through the cervix into the uterus, and a laparoscope is used to observe the flow of methylene blue through the fallopian tubes. If the tubes are unobstructed, the blue dye spills into the pelvic cavity. If there is a blockage, the dye will stop at that point, indicating the location of the obstruction. Additionally, laparoscopy allows direct visualization of adhesions around the fallopian tubes, the sites of adhesion, the degree of adhesion, and the relationship between the fallopian tube fimbriae and the ovaries.
2. Hysterosalpingography (HSG): The contrast medium can be seen on the fluoroscopy screen and photographs, revealing the shape and position of the uterine cavity and the fallopian tubes. In unobstructed tubes, the image extends beyond the fallopian tube fimbriae, and the contrast medium can be seen diffusing into the pelvic cavity on the X-ray. If the fallopian tubes are blocked, the obstruction can be identified. This method can also detect tuberculous lesions in the endometrium, fallopian tubes, and pelvic cavity.
