Guyon Urethral Bougies 20 Fr.

Clinical Application

Guyon urethral bougies in 20 Fr are used to assess and maintain urethral patency, dilate short-segment urethral strictures, and facilitate exchange or placement of urinary catheters and stents when a larger-caliber conduit is required. The size is selected to match the intended catheter or device diameter and to progressively dilate the urethra under direct tactile feedback. Common settings include urology clinics, operating rooms, and ambulatory surgery centers for procedures such as urethral calibration prior to instrumentation, intraoperative dilation, and pre-catheterization preparation.

Design & Configuration

The Guyon pattern is characterized by a smoothly tapered tip and a semi-rigid shaft that balances flexibility with enough stiffness for controlled passage through the urethral lumen. Atraumatic tapering minimizes mucosal trauma during blind passage while the semi-rigid configuration transmits tactile cues to the operator, helping differentiate true lumen passage from false passage. The smooth, polished surface reduces friction during insertion and withdrawal.
