Lister Urethral Bougies 9/12 FG

Clinical Application

Designed for controlled urethral calibration and gentle dilation, these Lister-style bougies are used to assess urethral caliber, traverse short strictures, and facilitate placement or exchange of urinary catheters and introducers. Their small-diameter 9 Fr and 12 Fr sizes are appropriate when a low-profile instrument is required for narrow urethral segments, pediatrics, or when gradual upsizing is planned. Common clinical settings include urology clinics, ambulatory surgery centers, and operating rooms during diagnostic cystoscopy, urethroplasty preparation, or catheter management.

Design & Configuration

The straight Lister geometry provides direct tactile feedback and precise control during insertion, enabling the operator to detect resistance and estimate stricture characteristics. A smooth, atraumatic rounded tip minimizes mucosal trauma during passage, while a firm, smooth shaft supports controlled advancement and withdrawal. Offering two discrete French sizes allows stepwise dilation and selection of an appropriate caliber based on the clinical scenario.
