Coudé catheter

 

 

Like the standard straight Foley catheter, the Coudé catheter is retained by means of a balloon at the tip which is inflated with saline. The balloons typically come in two different sizes: 5 cc and 30 cc. A Coudé catheter  is designed with a curved tip that makes it easier to pass through the curvature of the prostatic urethra.
