Theory of hydrokinetic clearance of bacteria from the urinary bladder. II. Effects of "bound" organisms and diuresis

Abstract

When patients with urinary infection drink large volumes of water and empty the bladder at frequent regular intervals, the concentration of bacteria in the voided samples commonly falls rapidly at first and then remains almost constant. The present theoretical analysis leads to the conclusion that the rapid initial fall in concentration is a function of diuresis and that the subsequent constant output originates from bacteria bound to multiplication sites on the uroepithelium from which their progeny are shed into the urine.
