Guyon Urethral Bougies 21 Fr.

Clinical Application

Designed for controlled urethral dilation and calibration, this 21 Fr bougie is used to establish or confirm a 21 French urethral caliber, negotiate urethral strictures, and facilitate safe passage of catheters or introducers. It is used in urology clinics, operating rooms, ambulatory surgery centers, and emergency settings for both diagnostic and therapeutic procedures. The instrument may be passed blindly or under endoscopic guidance depending on clinical judgement and the anatomy of the urethra.

Design & Configuration

The Guyon pattern provides a smooth, single-piece shaft with a gently tapered, atraumatic rounded tip to minimize mucosal trauma during passage. The polished surface reduces friction while advancing through the urethral lumen. A semi-rigid feel gives tactile feedback to help the clinician identify resistance from strictures versus normal anatomic narrowing, supporting safer dilation and accurate calibration.
