The objective of this study was the investigation of the influence of chlamydial, mycoplasmal and trichomonas infection on the development of urinary bladder leukoplakia. The article presents the results of the examination of women with chronic cystitis complicated with leukoplakia of the bladder, and associated with concomitant sexually transmitted infections, including the results of culture analysis of the cervical canal content and urinary bladder biopsy samples, as well as molecular-biological analyses confirming the presence of sexually transmitted infections, pathomorphological characteristics of tissue samples from leukoplakia foci typical for different types of infectious agents. In this study, 60 women with chronic cystitis, complicated with leukoplakia of the bladder and associated with concomitant sexually transmitted infections were examined. Using PCR diagnostics, Mycoplasma hominis and Chlamydia albicans were found to be the most frequently occurring agents, followed by Ureaplasma urealyticum, Chlamydia trachomatis and Trichomonas vaginalis. The results of culture analyses demonstrated that M. hominis and U. urealyticum were prevalent in patients with chronic urinary tract inflammatory processes, followed by Tr. vaginalis. Candida fungi show practically the same frequency of occurrence. The pathomorphological examination of the foci of leukoplakia in the urinary bladder (in 30 subjects) demonstrated metaplasia of the transitional epithelium to the stratified pavement squamous epithelium with inflammatory cellular infiltration of the lamina propria in all types of infections. The intensity of the urothelial transformation and stromal inflammatory processes were determined by the type of predominant infection. Pathomorphological characteristics of the foci of leukoplakia correlate with the etiology of chronic inflammation and are relevant for etiological diagnosis and treatment.
