MATHEMATICAL-MODELING OF THE CONCENTRATION OF MICROORGANISMS IN THE URINARY-BLADDER UNDER SIMPLE CONDITIONS

Mathematical relationships for simple models of the filling and evacua tion of the urinary bladder have been found and analyzed. These make t he determination of the concentration of microbes in the urinary bladd er at a given moment possible in relation to different parameters such as the rate of urine flow from the ureters, the microbe concentration in urine, the reproduction rate of microorganisms, the capacity of th e urinary bladder and the size of the residue which remains in the bla dder after miction.
