Guyon Urethral Bougies 25 Fr.

Clinical Application

Designed for controlled urethral dilation and calibration, this instrument is used to traverse the urethral lumen when placing catheters, assessing the caliber of strictures, or preparing the urethra for endoscopic procedures. The 25 Fr size is intended for cases requiring a larger-caliber dilator—commonly encountered in adult urologic practice for dilation, therapeutic calibration, or as an introducer for larger catheters and devices. Use with appropriate lubrication and under sterile technique; selection should be based on clinical judgment and urethral anatomy.

Design & Configuration

The Guyon pattern provides a semi-rigid shaft with a progressively tapered profile that balances column strength with the flexibility required to follow the urethral curvature. A smooth, rounded atraumatic tip reduces mucosal catching and trauma during passage. The straightforward single-shaft geometry simplifies handling and tactile feedback, allowing clinicians to sense resistance at strictures or false passages while maintaining controlled dilation.

Instrument Specifications
