Anti-fouling Silicone Urinary Catheter for Adults Needing Long-term Catheterisation: a Pilot and Feasibility Study

Sponsor: National Cheng-Kung University Hospital

Summary

This single-centre randomised pilot and feasibility study assessed whether an anti-fouling zwitterionic silicone urinary catheter can be deployed and evaluated in frail, elderly adults who require long-term indwelling catheterisation. In the experimental catheter, a zwitterionic polymer is blended into the silicone matrix rather than applied as a surface coating. Forty participants were randomly allocated to the anti-fouling catheter or a conventional commercial silicone catheter, with monthly catheter changes for up to eight cycles. The primary aim was to establish feasibility and acceptability (recruitment, retention, specimen completeness, safety and patient/family acceptability) and to obtain exploratory effect-size estimates (catheter-associated urinary tract infection, catheter-removal pain, urinalysis and urine culture) to inform the design of a future confirmatory trial. The study was not powered to test efficacy.
