• Catheter sizes for men are between 12Ch & 16Ch. • The smallest size should be chosen to provide adequate drainage. • Larger sizes can cause irritation & bypassing of The French scale or French gauge 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, Ga, FR or F. It may also be abbreviated as CH or Ch (for Charrière, its inventor). The charriere (Ch) size or French gauge is the external diameter of the catheter. Select the smallest charriere size that will allow effective drainage. Regarding length, female catheters should be used for routine catheterisations.

It may also be abbreviated as CH or Ch (for Charrière, its inventor). The French size is three times the diameter in millimeters.
Catheters vary by caliber, tip configuration, number of ports, balloon size, type of material, and length. Caliber is standardized in French (F) units—also known as Charrière (Ch) units. Each unit is 0.33 mm, so a 14-F catheter is 4.6 mm in diameter. 2014-12-01

So, for example, if a two-way catheter of 20 Fr is compared to a 20 Fr three-way catheter, they both have the same external diameter but the two-way catheter will have a larger drainage channel than the three-way. Catheter Selection - Size • The internal diameter of a catheter is measured in Charriere (Ch) – one Ch equals 1/3 mm, therefore 12 Ch equals 4 mm.

Choose the smallest catheter that will allow adequate urinary drainage. Size 12–14F is usually adequate for males and females. Use size 16 The size of the catheter inserted during the initial procedure must be maintained during future catheter changes.
