Millions of people around the world use urinary catheters every day. The tubes running in and out of their bodies provide a safe way out for urine but leave people constantly open to the risk of infection. A species of bacteria called Proteus mirabilis is particularly adept at building crusty scaffolds that eventually block the catheter tubes. We call these layers of bacteria biofilms and they are a serious problem; out of reach of the immune system and impenetrable to antibiotics, they thrive on medical devices.
An estimated million catheters are fitted every year globally, a quarter of these in the US. Up to half of people who use catheters long-term will at some point experience a blockage caused by a bacterial biofilm. This is bad news. When a catheter blocks, urine can no longer drain into the collection bag and so pushes back up from the bladder into the kidneys. There the bacterial infection builds where it can cause kidney failure, septicemia and death.
Our lab at the University of Bath has developed an early warning tube-coating system to detect biofilm build-up before a blockage can occur. The coating has two layers: the first layer is made up of a material that responds to changes in pH.
This caps the second layer, a bright yellow dye. The change in pH draws calcium and magnesium deposits from the urine that solidify into biofilms and block the flow of urine through the catheter tubing. Our system exploits this pH change: the increasingly alkaline urine dissolves the top layer and releases the dye before the film builds up enough to create a blockage. The dye floods into the bladder, mixes with the urine and drains out into the collection bag where the color change signals infection.
The coatings work up to 12 hours in advance of a blockage. In our experiments we used a glass bladder and artificial urine infected with P. We allowed the urine to flow until a blockage formed, marking the end point of the experiment. We monitored changes in the color of fluid in the collection bag over time. We found that four hours after the bacteria were introduced, the urine began to change color.
A blockage typically formed 16 hours later. The color change was strongest after six hours. Because infection rates are so high in people who use catheters, people are often given antibiotics to try to prevent infection. There are even catheters available that are impregnated with antibiotics.
However, this is controversial given the increasing problem of antibiotic resistance: using antibiotics to prevent, rather than treat, infection can reduce their efficacy and contribute to resistance. This will save money by reducing the number of serious infections and by preventing the unnecessary use of antibiotics. Our system could therefore help tackle antibiotic resistance. Biosensors and Bioelectronics is the principal international journal devoted to research, design, development and application of biosensors and bioelectronics.
He moved to Bath in and has subsequently built up a research group with a focus on medical device infection prevention and sensing via the development of new materials.

Your District Nurse or Continence Advisor will advise you on which type may be appropriate for your needs.

You may wish to discuss this with your partner. In some cases when long term catheterisation is needed longer than 30 days , the preferred method of drainage is via a suprapubic catheter.
This method involves a small operation to form an artificial track directly into the bladder and the catheter is inserted through the lower abdominal wall directly below the belly button. Both men and women can have this type of catheter. This type of catheter is generally administered when the urethral route cannot be used or if a person is still sexually active.
A Suprapubic catheter is normally inserted whilst in hospital and may require an overnight stay, however, the routine changes to the catheter can be done at home.
Many District Nurses and Continence Advisors are well practised in this procedure. Some people prefer to cover the site with a dry dressing but this is only necessary for the initial few weeks after insertion or if there is leakage or exudate.
The area needs to be kept clean by daily bathing or whilst showering, or by cleansing with soap and water and drying well afterwards. These are available on prescription, see your Healthcare Professional for information.
