Guyon Urethral Bougies 21 Fr.

Clinical Application

Designed for controlled urethral calibration and atraumatic dilation, this Guyon urethral bougie is used to assess lumen patency, negotiate short strictures, and provide a stable guide for subsequent catheter or instrument passage. The 21 Fr size is commonly selected for adult urethral work when a mid-range dilator is required for catheter exchanges, stent placement assistance, or to confirm lumen diameter during diagnostic or therapeutic urology procedures.

Design & Configuration

The instrument's tapered, atraumatic tip facilitates smooth entry and passage through the urethral meatus and narrowed segments while minimizing mucosal trauma. A single-piece, stiff-enough shaft provides tactile feedback so the clinician can discern resistance and negotiate anatomy with control. The 21 Fr diameter offers a balance between effective dilation and procedural control in adult cases.
