Why do so many long-term catheter users keep getting infections, even after treatment? For thousands of patients, the cycle of pain, blockages, and repeated antibiotic courses simply never ends.
In this article, we are going to learn how medical devices for indwelling catheter infection are changing the way healthcare providers tackle this problem.
The Real Reason Catheter Infections Keep Coming Back
Bacteria don't just float freely around a catheter. They stick to the surface and form a tough, sticky layer called biofilm and once it forms, it's very difficult to manage and reduce the infection without changing the catheter. Antibiotics can struggle to reach bacteria embedded inside biofilm, so even after a course of treatment, infection can return.
Biofilm can also trap minerals and debris over time, potentially blocking the catheter tube and causing urine to bypass the catheter, pain, and unplanned hospital visits. Standard catheter care only cleans the outside surface — it doesn't reach the inner wall where bacteria are colonising and multiplying.
That's why the same patients often face repeated infections, repeated antibiotic courses, and growing concern around antibiotic, not to mention prolonged hospital stays and risk of urosepsis.
This is exactly where dedicated medical devices for indwelling catheter infection management play a critical role.
Key Medical Devices for Indwelling Catheter Infection Prevention
UroShield —Surface Acoustic Wave Device
UroShield is an ultrasound device that clips directly onto an indwelling urinary catheter. According to the manufacturer, it generates low-frequency, low-intensity Surface Acoustic Waves that travel up and down the catheter, these surface acoustic waves interfere with bacterial attachment to the catheter surface, and reduce biofilm development.
Uroshield benefits include helping reduce bacterial attachment, lowering blockage risk from sediment accumulation, reducing catheter-related pain, and reducing the need for repeated antibiotic courses.
Individual results may vary, and patients should speak with their healthcare professional to determine suitability. A full starter kit is required — the actuator is single-use and should be replaced with every catheter change.
Meatal Dilators — Tapered Tip Urethral Access Devices
Meatal dilators feature a tapered tip designed to gently widen the urethral opening for easier passage, particularly helpful where strictures are restricting urinary flow.
When urinary flow is restricted urine can remain in the bladder and not empty completely this increases the UTI risk to high. By opening up the strictures urine can flow easier in turn allowing full bladder emptying.
ISC Catheters
Under the recommendation and training of the specialist team it may be suggested the patients carry out their own catheterization this is known as intermittent self-catheterization (ISC) this means the bladder can be fully emptied multiple times a day without the discomfort of leaving the catheter in situ and increasing catheter associated urinary infections (CAUTIs)
One of the limitations of this is the patients ability to be able carry out the procedure multiple times a day and the trauma that can be caused to the ureter. When repeated trauma is caused the infection risk increases again.
