Choosing the Right Catheter: Exploring the Differences and Benefits of External and Intermittent Catheters

Navigating the world of catheters can be complex, especially when considering the different types available. Two common options are the external catheter and the intermittent catheter. 

Understanding external catheters:

External catheters, also known as condom catheters, are designed to be worn externally. They consist of a sheath that fits over the penis, typically secured with an adhesive or a strap. The catheter connects to a drainage bag, allowing urine to flow away from the body.

Understanding intermittent catheters:

On the other hand, intermittent catheters are inserted into the bladder through the urethra at specific intervals to empty the bladder. Unlike indwelling catheters, intermittent catheters are designed for short-term use, providing a practical solution for individuals who can manage the catheterization process.


  • Application:
    • External Catheter: Applied externally, avoiding the need for insertion into the urethra.
    • Intermittent Catheter: Requires insertion into the urethra for the purpose of emptying the bladder.
  • Wear Time:
    • External Catheter: Worn continuously as long as needed.
    • Intermittent Catheter: Used periodically, typically every few hours or as recommended by healthcare professionals.
  • Risk of Infection:
    • External Catheter: Lower risk of urinary tract infections as it doesn’t enter the urethra.
    • Intermittent Catheter: Requires careful hygiene to minimize the risk of infection associated with inserting a catheter.


  • External Catheter Benefits:
    • Non-Invasive: Ideal for individuals who prefer a non-invasive option.
    • Reduced Infection Risk: Lower risk of urinary tract infections compared to internal catheters.
    • Easy Application: Simple to apply and remove.
  • Intermittent Catheter Benefits:
    • Customized Usage: Can be used intermittently, allowing for better control over bladder function.
    • Reduced Residual Urine: Effective in fully emptying the bladder, reducing the risk of urinary retention.
    • Versatility: Available in various types and sizes to accommodate different needs.

In the realm of catheters, the choice between external and intermittent catheters ultimately depends on individual preferences, medical conditions, and lifestyle. External catheters offer a non-invasive option with reduced infection risks, while intermittent catheters provide a more controlled approach to bladder management.

Whether you opt for the simplicity of an external catheter or the precision of an intermittent catheter, it’s crucial to consult with healthcare professionals to determine the most suitable option for your unique circumstances. 
With the right choice, individuals can confidently manage their bladder health and improve their overall quality of life. Explore the diverse range of catheter options available at BioRelief to find the solution that aligns with your needs and preferences.
