In an ideal world no one would have a catheter - but the reality is that 100m patients world wide rely on an indwelling urinary catheter and they are badly served by the ubiquitous Foley design

Bladder management with a catheter is needed by a million people in the UK who have problems caused by inability to pass urine or excessive leakage; older people and those with a disability are most affected. People who use catheters need to have them changed at least every 3 months, but often much more frequently. Patients often experience problems, such as catheter-associated urinary tract infections (CAUTI), catheter blockages, leaking and bladder spasms [Wilde et al. 2016]. CAUTI are the most frequent nosocomial infections
[Jacobsen et al., 2008]. The financial burden has been estimated in the UK NHS to cost hundreds of millions of pounds, due to delayed discharge, staff resources and antimicrobial treatment [Davenport & Keeley, 2005; Plowman et al., 2001]. A better catheter would reduce CAUTI and could provide annual savings of £500 million in the UK, and $18 billion in the USA [Feneley et al. 2015]. 

What we've learned from more than 120 Community nurses caring for 2,500+ catheter patients...

  • Infection; 48% of Foley users have been prescribed antibiotics for catheter associated urinary tract infections
  • Blockage; 45% block within 4 weeks, 65% within 8 weeks and 90% within 12 weeks
  • Leakage; 46% of patients suffer 'bypassing' (leakage) 

Amazing video reveals the source of the problem...

Professor Roger Feneley has devoted his entire career to urology and catheter related problems in particular....  Here he narrates a video that clearly highlights the issues of the Foley design, with the soft bladder mucosa collapsing onto the hard tip of the catheter and even being sucked into the drainage eyes, being torn away and becoming an inherent focus for infection


Perhaps one day modern science and technology will introduce a better urine collection system, to help these unfortunate patients.

 An extreme case of Foley encrustation....

An extreme case of Foley encrustation....

Many find the removal of catheters painful.. causes trauma and fear
Catheters frequently become encrusted. Some are a lot more troublesome than others but all would benefit from an alternative to a Foley catheter
