Chronic recurrent cystitis (CRC) is a common disease in the female population and a serious medical problem. There are not enough data about etiology of this desiase and effective treatment.To increase the accuracy of the differential diagnosis of bacterial and papillomavirus chronic recurrent cystitis.Analysis of endoscopic and morphological diagnostic methods of 118 patients with CRC, which, depending on the etiological factor, were divided into two groups. Group I (n=65) patients with CRC of HPV etiology and Group II (n=53) - CRC of bacterial etiology (E. coli). All patients were examined according to the EAU and RSU recommendations, and an endoscopic examination of the bladder (cystoscopy) was additionally included, followed by morphological examination of biopsy specimen of the urinary bladder.The endoscopic picture of bacterial CRC usually is caused by hyperemia of the mucous membrane of the bladder, hyperemia and injection of vessels with the participation of (small-puncture/diapedesic) hemorrhages without signs of proliferative changes. The endoscopic picture in papillomavirus CRC in all patients presented by focal or diffuse, slightly elevated, exophytic, often polypoid formations of a whitish or whitish-gray color, usually localized in the Leto triangle. Morphological analysis of biopsy tissue of the urinary bladder in patients with bacterial cystitis in the mucous and submucous layer showed edema, thickening of the urothelium, capillary abundance, inflammatory infiltration, represented by lymphocytes, plasma cells and leukocytes, among which neutrophilic macrophage leukocytes were predominant. Morphological analysis of the bladder mucosa in all examined patients with signs of HPV-related lesions showed a thickening of the urothelium, squamous metaplasia of the urothelium, chronic inflammation, microcirculatory vascular reaction and edema. An important distinctive pathomorphological sign of HPV within urinary bladder was the presence of koilocytic transformation of urothelium cells due to the cytopathic effect of the virus.Papillomavirus CR has characterized by an infectious-inflammatory process in the bladder paries, with lymphocytic-plasmatic infiltration and coylocytic transformation of the urothelium. |
