Methods Models of the catheterized bladder were infected with Escherichia coli. Artificial urine was supplied at various flow rates and various concentrations to separately assess the "flushing effect" and "dilution effect" of increased water consumption on catheter blockage time, encrustation formation, and bacterial growth. Results There were no statistical significances regarding catheter blockage time (P = 0.92), encrustation formation, and bacterial growth among bladder models supplied with various flow rates. When the flow rate was set as 1 ml/min, however, there showed significant decrease trend of the time to blockage (P = 0.0005), encrustation formation, and bacterial growth as the concentration of the artificial urine increased except the twofold-concentration urine group. Conclusions Increased water consumption is associated with beneficial effects of urinary tract infection prophylaxis and treatment, and dilution effect of bacteria nutrition in the urine is at least partly involved in this process if not all, rather than the "flushing effect". Considering the flaws and the in vitro design of the current study, however, an in vivo study is warranted.
