How to choose the right catheter
Choosing the right catheter involves considering various factors, including the individual’s medical diagnosis, anatomical characteristics, lifestyle and preferences. Some key considerations may include:
Type of catheter: Whether the person requires long-term or short-term catheterisation, their healthcare provider will recommend a suitable catheter type, for example, an intermittent catheter or an indwelling catheter.
Length: Catheter size refers to its diameter, which is measured in French units. The size one should choose depends on the size of the urethra as well as presence of obstructions. Catheter length depends on the patient’s anatomy with shorter catheters mainly used for female patients and longer catheters for male patients.
Material: Catheters can be made of a variety of materials including latex, silicone, plastic and PVC. Potential allergies and sensitivities to these materials need to be taken into consideration when choosing a catheter.
Tip design: Straight tip is suitable for most users. Coudé tip (curved tip) is designed to navigate past obstructions in the urethra, which makes it suitable for users with anatomical abnormalities.
Coating: Some catheters come with lubricating coating in order to reduce friction during insertion and minimise the risk of trauma.
Lifestyle and personal preference: Personal preference, daily routine and activity level are also important when selecting a catheter. For example, such factors as discretion, ease of use and portability may influence a patient's choice. Choosing the right catheter is very important. Catheter users may need to try different catheters to see which one suits them best.
