Guyon Urethral Bougies 18 Fr.

Clinical Application

Designed for urethral calibration and gentle dilation, this Guyon pattern bougie is used to assess lumen caliber, negotiate short, passable strictures, and facilitate atraumatic placement of urinary catheters or introducer devices. Commonly used in urology clinics, ambulatory surgery centers, and operating rooms for both diagnostic calibration and staged dilation during endoscopic or open procedures.

Design & Configuration

The straight, tapered geometry with a smooth, rounded tip minimizes mucosal trauma while allowing controlled progression through the urethral lumen. The Guyon pattern provides a firm, predictable profile that helps clinicians sense resistance and the location of strictures. An 18 Fr diameter corresponds with commonly used catheter sizes, making this size practical for transitioning from bougie-guided dilation to Foley catheter placement.
