Causes of female urethral tube blockage

There is an old Chinese saying: There are three types of unfilial behavior, and the worst is to have no descendants. The body is the foundation for the continuation of the family line, but due to the stress and fast pace of modern life, as well as irregular daily diet, more and more cases of infertility in men or women are occurring. One of the causes of female infertility is blockage of the female uterus. So what are the reasons for blockage of female urethral tube?

Fallopian tube blockage is the main cause of female infertility, accounting for 25% to 35% of female infertility, and the main cause of fallopian tube damage is pelvic inflammatory disease (PID). The incidence of secondary fallopian tube obstruction is directly related to the incidence of PID. Reproductive capacity after fallopian tube reconstruction depends on the site and extent of fallopian tube damage. Women with extensive fallopian tube damage have a lower chance of becoming pregnant, and IVF can improve their pregnancy rates.

Causes:

1. Infection

Most cases of fallopian tube disease are secondary to infection, particularly pelvic inflammatory disease (PID). Other possible causes of infection include a perforated appendix, infection after abortion, or postoperative complications, such as endometriosis and inflammatory states caused by surgery, which can lead to occlusion of the fallopian tubes due to adhesions. Rarely, embryologically absent fallopian tubes are a factor in infertility, and the final cause may also be iatrogenic, such as tubal ligation.

Although pelvic inflammatory disease can be caused by a variety of microorganisms, chlamydia is the main cause of infertility. Damage to the fallopian tubes may already exist before the application of antimicrobial therapy. Sometimes the infection may be subclinical and exist in the fallopian tubes for months before diagnosis and treatment. This is in stark contrast to the acute onset of PID caused by Neisseria gonorrhoeae. It is now highly suspected that chlamydia infection damages the mucosa of the fallopian tube through immunopathological mechanisms, while Neisseria gonorrhoeae damages the fallopian tube through related cytotoxicity. Other latent infectious pathogens include Mycoplasma hominis and endogenous aerobic or anaerobic bacteria. Pelvic tuberculosis accounts for 40% of tubal infertility in developing countries.

Infectious abortion is another major risk factor for tubal infertility. Preoperative examinations include bacterial vaginosis and cervicitis. Culture and serological tests should be performed when necessary, and the test results should be understood before surgery. We routinely use preventive antibiotics after abortion.

2. Inflammation/adhesion

Tissue trauma caused by surgical operations can also lead to a pre-inflammatory state or even adhesions. The incidence of postoperative adhesions is approximately 75%, and laparoscopy cannot prevent the occurrence of adhesion sequelae. The application of adhesion barriers (such as anti-adhesion membranes) can reduce the occurrence of adhesions by an average of 50%. The removal of adhesions will increase the rate of infertility. If severe diseases exist, in vitro fertilization-embryo transfer (IVF-ET) may be the only option.

prevention:

1. Pay attention to the cleanliness and hygiene of the reproductive system. Preventing infection from various pathogens (especially sexually transmitted diseases) is the most critical. During artificial abortion, delivery, removal and placement of intrauterine contraceptive devices, and other uterine surgery, strict disinfection should be carried out to avoid inappropriate uterine operation, unclean sexual life, sexual intercourse during menstruation, repeated fallopian tube insufflation, etc.

2. Actively cure pulmonary tuberculosis and lymph node tuberculosis to prevent infection of pelvic tuberculosis.

3. Once a woman suffers from adnexal disease, she should abide by the treatment principles, take a positive attitude, seek thorough treatment, control the disease as soon as possible, and prevent it from becoming chronic.

4. Strengthen exercise and enhance disease resistance.
