French Size (FR) determines the diameter of the catheter, which is crucial for comfort and effective drainage. Choosing the right size is important: a size too small may not drain efficiently, while a size too large may cause discomfort or trauma. The most common sizes range from 8 FR to 18 FR, allowing users to select the best fit for their anatomy and medical needs. For example, the Coloplast 450 Self-Cath Straight Tip, 14 FR provides a mid-range size that balances comfort and effective drainage for many users. There are multiple FR sizes available within this category so you can find the ideal fit for your needs.
