A clinical assessment of the performance of a sensor to detect crystalline biofilm formation on indwelling bladder catheters

Abstract

The cellulose acetate/bromothymol blue sensors placed in the urine collection bags are capable of signalling infection by P. mirabilis. They also signal the early stages of catheter encrustation and allow catheter replacement in ample time to avoid the clinical crises and emergency referrals caused by catheter blockage.
