VIRAL ETIOLOGY OF RECURRENT URINARY TRACT INFECTIONS

Abstract

Introduction. Recurrent urinary tract infection is an actual problem of modern urology.

Objective. Complex investigation of urinary tract infections including viral etiology for chronic recurrent cystitis in women

Materials and methods. The study included 31 women with recurrent infection of urinary tract. Inclusion criteria were the presence of lower urinary tract symptoms caused by infection, severe recurrent course, the lack of anatomical and functional disorders of the urinary tract, the absence of bacterial pathogens during the study, taking into account the culture of aerobic and anaerobic culturing techniques.

Results. The analysis of the clinical manifestations, the dominant in the study group were pain and urgency to urinate at 100% and 90% of women surveyed, respectively, and less frequent urination were recorded in 16.1% of patients. In general clinical examination of urine in all cases identified leukocyturia and 90% of the hematuria. By using a polymerase chain reaction (PCR) in midstream urine of all examined was verified 10 types of human papilloma virus (HPV) with the predominance of 16 and 18 types . Considering the presence of recurrent infectious and inflammatory processes of the urinary tract, cystoscopy with bladder biopsy was performed for all patients. When histomorphological biopsies of all patients surveyed noted the presence of the specific characteristics of HPV: papillary hyperplasia with squamous koilocytosis, pale cytoplasm and shrunken kernels. When analyzing the results of PCR biopsy data corresponded with the results of PCR in midstream urine in all biopsies was detected HPV.

Conclusions. Human papillomavirus infection may be involved in the development of viral cystitis. In the etiological structure of viral cystitis, both highly oncogenic and low oncogenic HPV types can act.
