The current trends in understanding the pathogenesis of infectious and inflammatory urogenital disorders are highlighted in the review. The etiological and pathogenetic significance of increased intestinal permeability for pathogens in the development of various diseases has been convincedly proved. There is no doubt about the pathogenetic role of increased permeability of the bladder mucosa, which can result in interstitial cystitis (IC). The association of intestinal diseases with IC has been established. In rats, the induction of intestinal inflammation may cause increased permeability of the bladder mucosa. In the postoperative period, bacteria are translocated from the gastrointestinal tract to the urinary tract, which is associated with stress.
Particular attention is paid to the therapy based on new knowledge about the pathogenesis of infectious and inflammatory diseases of the urogenital tract. Possibilities of decreasing intestinal and bladder permeability using rebamipide are described. Various therapeutic mechanisms of action made it possible to use this drug in endoscopy, ophthalmology, chemotherapy and rheumatology. The antioxidant and anti-inflammatory properties of rebamipide has been shown in-vitro. Intravesical instillation of rebamipide accelerates the recovery of damaged urothelium and its barrier function, and also influences on bladder hyperactivity. Thus, the first results of using rebamipide in urology are encouraging; however, further researches are required.
