Urological stents and catheters often lead to inflammation, causing pain and infection in the urinary tract. Moreover, 80% of stents are associated with pain, negatively impacting on QoL and mental health. Offering novel designs with significantly lower E\&B leads to a reduction in UTIs and improves QoL. Reducing hospital admissions (from 3 to 1 per patient, annually) would free \>100,000 bed-nights, allowing the elderly to regain independence. Our proposed research could have a significant impact towards fulfilling the 'healthy-ageing' Grand Challenge. Additionally, the novel stent reduces prevalence of infections and therefore, of antibiotic prescriptions contributing to the Global AMR challenge.
