Catheter Maintenance with Uro-Tainer®

A large number of patients are catheterised especially in primary care settings to manage urinary incontinence. Due to the ageing of the population the number of patients affect is still expanding despite efforts to limit indications for catheterisation. Complications can affect up to 70% of catheterised patients, negatively impacting their quality of life and increasing the cost of care.

A US study highlighted the most common catheter-associated complications as leakage, urinary tract infection, UTI for short, and blockage.

US Study 202 Patoents
Long-term indwelling urinary catheter

The longer the catheter is in situ, the greater the risk of complications. About 50% of patients catheterised for more than 7-10 days develop bacteriuria.
… and 20-30% will go on to develop a UTI.



Catheter removal may be the only option to manage complications but this may in turn lead to further risk of infection and discomfort for the patient 

Catheter maintenance is therefore required to prevent complications and unnecessary removal of the catheter.

Uro-Tainer – Leading the way in catheter maintenance

The Uro-Tainer® product line consists of a 100ml PVC-free bag with different fluids which have their own distinct indications for use to manage catheter blockage (see Table 2). Uro-Tainer® Suby G and Uro-Tainer® Solutio R are also available as a double bag§ to enable sequential rinsing with smaller volumes. Uro-Tainer® NaCl 0.9 % is also available with an injection port** to enable administration of drugs. The Uro-Tainer® device is a closed system and is connected to the catheter and administered by gravity. After the instillation, the fluid is returned to the same bag.

Compared to alternatives the benefits of the Uro-Tainer® system are:
Contamination is minimised and product safety enhanced as

  • The universal catheter tip is sterile and has an attached protective cap
  • It is a completely closed system
  • The exterior of the device is sterile when the package is opened

Patient comfort and safety is maximized as

  • The device has a simple and safe operating mode (gravity as sole input and output force)
  • It can be easily used by healthcare professionals as well as the patient

Catheter blockage can result from a number of different causes. Therefore, discovering the exact cause of the blockage is important as this influences the choice of treatment approach. If the useful life of the catheter is threatened by encrustation or debris formation, intervention with the correct Uro-Tainer® rinse fluid, in addition to a healthy diet and sufficient fluid intake, can increase the catheter’s lifespan17

 Role of the catheter diary

A catheter diary is a helpful monitoring tool for catheterized patients. It can help all the healthcare professionals involved with the patient to highlight any problems with the catheter at an early stage and initiate a suitable management plan

The diary enables the monitoring of the catheter lifespan and any contributing factors to blockage e.g. infection etc

A clear picture of the catheter’s lifespan is usually evident after three to five catheters are evaluated17

Blockages resulting from calcification and encrustation can usually be identified using a catheter diary in conjunction with a combination of:

pH-indicator - Check urine pH regularly since alkaline urine (indicated by pH > 6.8) is a strong indication of possible calcification (64). pH can be measured using pH strips

Culture - Bacteria in the urine, such as Proteus mirabilis, in combination with alkaline urine create ideal conditions for the onset of calcification

Inspection - If it is suspected that a blockage has resulted from calcification, checking the catheter by cutting it open along its length after it has been removed is recommended. If the catheter is blocked and the blockage cannot be attributed to calcification this is a good indication that debris formation is the cause of the blockage
