Webb18 feb. 2024 · The size of the catheter refers to the diameter of the tube and is measured in French units (Fr). If urine is leaking from around the catheter or draining too slowly, you may be using a catheter that is too small. On the other hand, if you are experiencing pain when inserting your catheter, it may be because your catheter is too large. The French scale, French gauge or Charrière system is commonly used to measure the size of a catheter. It is most often abbreviated as Fr, but can often be seen abbreviated as Fg, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). However, simply gauge, G or GA generally refers to Birmingham gauge. The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 m…
