Indwelling urinary catheters become repeatedly blocked in up to 50% of long-term catheterised patients leading to urinary retention, pain and an increased risk of infection and death.

Blockages result from crystals forming in the urine which attach to the surface of the catheter. The novelty of this pharmacological study is that by using compounds to prevent encrustation, it has the potential to create the first self-regulating and blockage-resistant coating system for catheters.
