Infertility should be vigilant against fallopian tube blockage. Six precautions for examination should be taken seriously

Tubal obstruction is a common infertility that seriously affects women and families. After infertility, it is important to seek medical attention and pay attention to its symptoms.

Symptoms of blocked fallopian tubes

1. Irregular menstruation: Women with blocked fallopian tubes experience irregular menstruation, such as frequent, excessive, or insufficient menstrual flow. When female friends experience ovarian dysfunction, it can lead to menstrual irregularities.

2. Abdominal discomfort: Patients with blocked fallopian tubes often experience discomfort in the lower abdomen. For example, hidden discomfort such as lumbar discomfort and back discomfort may cause the abdomen to fall or expand, and the condition may worsen when fatigue is excessive.

3. Dysmenorrhea: Female pelvic congestion can easily cause congestive dysmenorrhea, which often occurs about a week before menstruation, and the closer it is to menstruation, the more obvious the pain.

4. Infertility: The blockage of the fallopian tube can not combine sperm and eggs into zygote, causing infertility.

5. Symptoms such as increased vaginal discharge, pain during sexual intercourse, general weakness, and mental depression.

Inspection method for tubal obstruction

1. Hysterosalpingography: Hysterosalpingography can reveal the size, shape, and position of the uterine cavity, as well as the shape of the fallopian tubes, from fluorescent screens and X-ray photographs. For smooth people, the image extends beyond the port of the fimbriae of uterine tube, and the X-ray can simultaneously see the contrast agent scattered in the pelvis. When the fallopian tube is blocked, the location, degree, and nature of the blockage can be clearly displayed. This method can also identify endometrial, fallopian tube and pelvic tuberculosis lesions. At present, the most reliable method for diagnosing tubal patency can achieve an accuracy of over 98%. And the inspection cost is low.

2. Laparoscopic examination: inject pigment solution such as methylene blue into the uterine cavity through the uterine catheter, and observe the methylene blue overflowing into the pelvic cavity through the fimbriae of uterine tube end through laparoscopy, which means it is unobstructed; If there is blockage at the proximal end of the fallopian tube (interstitial part and isthmus of the fallopian tube), no methylene blue solution can be seen to overflow into the abdominal cavity through the fimbriae of uterine tube end. If there is blockage at the distal end of the fallopian tube (ampulla and fimbria of the fallopian tube), it can be seen that the end of the fimbriae of uterine tube and ampulla are dilated and thickened and blue stained, but no methylene blue fluid flows from the end of the fimbriae of uterine tube and into the abdominal cavity.

3. Tubal irrigation: also known as tubal irrigation, tubal irrigation inserts the tube into the examiner's uterine cavity and injects 20ml of medication through the tube. The medication is usually added to physiological saline with antibiotics. The medicine flows through the fallopian tubes from the uterine cavity and finally reaches the pelvic cavity. According to the characteristic that the uterine cavity can only accommodate 5ml of volume, if 20ml of solution can be smoothly injected and the needle tube is relaxed, the liquid does not flow into the needle tube, indicating that the solution enters the abdominal cavity through the uterine cavity and fallopian tube cavity, indicating a high resistance to fallopian tube patency. After the needle tube is relaxed, more than 10ml of solution flows into the needle tube
