Catheter associated urinary tract infection

Catheter associated urinary tract infection is the most frequent HAI, of which a large proportion is caused by indwelling urinary catheters.1

These infections are often caused by urinary catheters and can result in serious complications that cause a great deal of suffering for the patient, a higher mortality rate and increased healthcare costs.

The natural process of protecting the urinary tract against bacteria or other microbes (urethral immune defense, regular emptying of bladder) is compromised during catheterization and the risk for invasion of bacteria and subsequent infections increase with every day of catheterization.

How does CAUTI occour?

CAUTI occurs when bacteria enter the urinary tract or bladder. It is common that bacteria adhere, colonize and form biofilm on the catheter inner and/or outer surface.

The bacteria might come from the patient herself or from external sources such as personnel, other patients or medical devices. Bacteria forming biofilm are more resistant to the patient’s immune system and antibiotics.

Common symptoms of CAUTI

  • Fever
  • Chills
  • Urgency
  • Pelvic pain
  • Bladder and/or urethral pain
  • Nausea
  • Loss of appetite


Urinary tract infections that are not treated can spread to the kidney, causing more pain and illness and it may develop into urosepsis. This is particularly common in people who have limited or no sensation below the waist or who are unable to speak for themselves. Sepsis can develop as the body´s overreaction to an infection, and is often deadly.

Sepsis kills and disables millions of people every year worldwide and requires early diagnosis and rapid treatment for survival.

69% risk reduction of CAUTI with Bactiguard’s Technology

A recently published (March 2021), large, randomized, controlled multicenter study in India with 1,000 patients included, shows that urinary catheters with Bactiguard’s coating for infection prevention reduce the risk of catheter-associated urinary tract infections (CAUTI) by 69 % compared to standard catheters.3 The study was published in the internationally renowned scientific journal “Antimicrobial resistance and infection control”. Read more about the study.

The unique Bactiguard technology reduces microbial adhesion on the catheter surface

The Bactiguard technology (Bactiguard Infection Protection) is based on a very thin noble metal alloy coating, firmly attached to the catheter surface. When in contact with fluids (urine), the noble metals create a galvanic effect which reduces microbial adhesion. This means that less bacteria adhere to the catheter surface, which reduces the risk of biofilm formation leading to infection.

The BIP Foley catheters are intended for patients catheterized longer than two days. Less than two days usage rarely leads to infection and a standard catheter can be used.
