[Leucoplakia vesicae in females: diagnosis and treatment].

Sixty patients suffering from leucoplakia vesicae (LV) were examined using cystoscopy with biopsy of the urinary bladder wall, blood enzyme immunoassay for detection of antibodies to agents of sexually transmitted infections (STI), uroflowmetry, culture analysis of cervical canal and mucosa samples for STI. As shown by a pathomorphological examination of the vesical mucosa biopsy specimens, long-term persistence of pathogenic (chlamydia, trichomonades) and opportunistic (mycoplasma, ureaplasma, fungi) flora underlies development of LV. Morphogenesis of LV is characterized by hyperplastic reactions of urothelium and its metaplasy in laminated squamous keratosic epithelium, often with para- and dyskeratosis, developing in the presence of inflammatory reactions in the lamina in the presence of persisting infection. In LV, specific infection agents are often found in the urogenital tract. The spectrum of these agents is identical for samples from the cervical canal and vesical mucosa from leucoplakia foci. Vesical mucosa is most frequently contaminated with Mycoplasma hominis (57.2%), Candida albicans (51.4%), Ureaplasma urealiticum (37.1%) and Trichomonas vaginalis (22.9%). Associations of the infection agents are detected in 70% of LV patients. Persistent dysuria is a basic clinical symptom of leucoplakia. The following therapeutic measures should be taken: transurethral coagulation of the vesical mucosa, intravesical therapy, immunocorrection, antibacterial treatment by standard schemes or according to the isolated flora sensitivity.
