The French size (FR) refers to the diameter of the catheter and is crucial for ensuring effective drainage and comfort during use. The "best" size depends on individual needs, anatomy, and physician recommendations. Smaller FR sizes, like 8 or 10 FR, are suited for pediatric or female users, or those with narrower urethras, while larger sizes, such as 14 or 16 FR, allow faster drainage for adult males or those needing higher flow. Options such as the Coloplast 610 Self-Cath Coude Tapered Tip 10 FR and Coloplast 116 Self-Cath Soft Catheter 16 FR demonstrate the available range. Multiple FR sizes are available, enabling users to choose the most appropriate diameter for their comfort and clinical needs.
