Urinary tract infection control

We present here a production of anti-bacterial zeolite TMA-Z balloon catheter and investigated its potential for controlling urinary tract infection. This anti-bacterial balloon catheter showed a bactericidal effect against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli in vitro studies. The antibacterial effects were correlated with the concentration of anti-bacterial zeolite and size of catheter. We tried this catheter for 11 various urological patients who needed a long-term indwelling of a balloon catheter for lower urinary tract obstruction and neurogenic bladder. All patients were already indwelled silicon balloon catheter for 3 to 6 months and suffered with complicated urinary tract infection. Nine patients who had this anti- bacterial zeolite TMA-Z balloon catheter indwelled for 3 to 7 months and exchanged every 2 to 4 weeks, and no patient was taking antibiotics during this trial. Two patients (22.2%) showed good results by the urinary tract infection (UTI) criteria and 5 patients (55.4%) showed good effects by doctor's judgment. This antibacterial zeolite TMA-Z balloon catheter might be useful for patients who need long-term balloon catheter indwelling.
