On a continent ostomy catheter, 30 Fr means the catheter has an outer diameter of approximately 10 mm. “Fr” stands for French size, a standard measurement used for the outside diameter of medical tubes and catheters.
A higher French size means a larger catheter diameter. Product specifications and healthcare guidance should be reviewed carefully to confirm the correct French size, catheter length, tip style, material, sterility, disposability, and compatibility with the customer’s continent ostomy system, such as a continent ileostomy or Kock pouch.
