Histological findings in pseudomembranous trigonitis

Summary
Pseudomembranous trigonitis, a bladder condition in women, involves unique trigone lesions. Histology reveals vaginal metaplasia without significant inflammation, suggesting hormonal influences on bladder epithelium.
Area of Science:
- Urology
- Gynecology
- Pathology
Background:
- Pseudomembranous trigonitis is a condition affecting the female bladder trigone.
- It is associated with urethral syndrome and presents with characteristic lesions.
Purpose of the Study:
- To analyze the histological features of pseudomembranous trigonitis.
- To investigate the potential role of estrogen stimulation in its development.
Main Methods:
- Histological examination of 31 cases of pseudomembranous trigonitis.
- Analysis of epithelial changes, edema, and vascularity.
Main Results:
- Histology showed 'vaginal metaplasia' of the trigone epithelium.
- Underlying edema and vascular dilatation were observed, but no significant inflammation.
- Thirty-one cases were included in the study.
Conclusions:
- The trigone's epithelium may respond differently to estrogen due to distinct embryological origins.
- Estrogen stimulation is a potential factor in pseudomembranous trigonitis development.
