How to know whether oviduct is blocked

summary

My wife and I had been pregnant for several years, but we didn't take any contraceptive measures, but we didn't expect to have a baby for several years. Later we learned that our wife had tubal blockage. In order to prevent this situation, let me introduce how to know whether the fallopian tube is blocked.

How to know whether oviduct is blocked

First: salpingography is one of the common examinations for patients with tubal obstruction. Contrast agent is injected into uterine cavity and fallopian tube through catheter. Then use X-ray diagnostic apparatus for X-ray fluoroscopy and radiography, according to the contrast medium in the pelvic cavity and fallopian tube development, in order to understand whether the fallopian tube is smooth, so as to carefully observe the blockage site and blockage.

Second: the best time for examination is 3-7 days after menstruation, commonly used preparations are 40% iodide, organic iodine preparation or iohexol; before contrast examination, iodine allergy test should be done first, and 2.5% iodine tincture should be applied on the flexure surface of forearm (about 2-3cm in diameter), and then scratch it, and observe whether there is swelling reaction after 20 minutes. Conjunctival instillation and intravenous injection of contrast agent are also common test methods. Skin urticaria, sneezing, chest tightness, laryngeal edema, etc. are all positive manifestations, suggesting iodine allergy; before angiography, patients should empty their bowels and urine, and take laxatives if necessary, so as to keep the uterus in the correct position.

Third: the patient lies on the X-ray machine operating platform, after routine disinfection, the injection is slowly injected under fluoroscopy. The first injection volume was 3 ~ 5ml, and the condition of entering uterus and oviduct was observed, and an X-ray was taken. Continue to push in the contrast medium, continue to take the film after 5-10 minutes, and then take the film at the same site after 24 hours. If there is no contrast medium in the pelvic cavity, it indicates that the bilateral fallopian tubes are blocked; if there is a small amount of contrast medium in the pelvic cavity, it indicates that the fallopian tubes are unobstructed.

matters needing attention

All patients had a small amount of vaginal bleeding after operation, and no special treatment was needed. If there was a large amount of bleeding, timely report to the doctor and assist the doctor to take hemostatic measures. Patients with nausea, vomiting, sweating, pale complexion and other symptoms were forbidden to have sex and bath for 2 months. Two months after the operation, menstruation was clean, and fluid was dredged for 3-7 days to prevent fallopian tube re adhesion.
