Medical Forum / Diseases and Disorders / Prostate BPH / August 2004fr numbers
What do fr numbers mean for catheters - do bigger numbers mean larger or smaller diameters please? The larger the number the larger the diameter of the catheter. I think there is a relationship of the number to the actual size in millimeters, but I don't recall the conversion factor.

Catheters sized from 14F to 20F--14F is the smallest 20F the largest(diameter). The larger the number the larger the diameter of the catheter. I think there is a relationship of the number to the actual size in millimeters, but I don't recall the conversion factor.

Divide the French size by 3 for the diameter in mm (e.g. an 18 Fr catheter has a diameter of 6 mm - approximately equal to 0.236 inches). Richard Slessor |
