(1) Pathogenic factors
Genital tuberculosis is generally considered a secondary infection. After pelvic organ involvement, the disease can directly spread to nearby organs, first invading the fallopian tubes.
When tuberculous salpingitis occurs, tuberculous bacteria mostly spread from tuberculosis lesions in other parts of the body, and the fallopian tube is more susceptible to tuberculous bacteria spread through blood than other parts of the female reproductive tract.
The structure of the fallopian tube mucosa is conducive to the incubation of Mycobacterium tuberculosis, which can be locally hidden for more than 1-10 years, leading to weakened immunity and reactivation of the disease.
Due to the slow onset of this disease, atypical symptoms are easily overlooked.
(2) Pathogenesis
1. Pathogenic bacteria:
The main pathogen of tubal tuberculosis is Mycobacterium tuberculosis, with only 5% of the pathogens being Mycobacterium tuberculosis.
2. Affected area:
Tubal tuberculosis often affects both fallopian tubes, and both fallopian tubes may be infected simultaneously or sequentially.
3. Development of the condition:
The further development of fallopian tube tuberculosis can cause endometrial tuberculosis, ovarian tuberculosis, and cervical tuberculosis, especially the endometrium in the uterine horn, which is most susceptible to invasion.
When infected with tuberculosis, the umbrella end is not sealed, which is easy to distinguish from the umbrella end of suppurative salpingitis.
If pelvic peritoneal tuberculosis is complicated, there are also scattered nodular lesions on the uterine serosa.
