[Urethrovesical reflux in patients with chronic cystitis].

We studied the role of urethrovesical reflux in the onset and maintenance of chronic inflammation in the urinary bladder in patients suffering from chronic cystitis combined with pseudopolyposis of the neck of the bladder and proximal part of the urethra. We modelled a simplified version of an urination fragment of a special computer graphic station. The original computer model theoretically proves the existance of urethrovesical reflux caused by pseudopolyposis in the zone of the urinary bladder cervix and/or proximal urethra. The data were confirmed by radionuclide investigation. Our studies proved the presence of urethrovesical reflux in patients with pseudopolyposis of the bladder cervix provoking retrograde infection of the lower urinary tract. We think it necessary to combine conventional conservative treatment of cystitis with endourethral surgical interventions aimed at reestablishment of normal urination.
