Lister Urethral Bougies 12/15 FG

Clinical Application

These Lister-pattern urethral bougies provide controlled urethral calibration and atraumatic dilation in diagnostic and therapeutic urology procedures. They are used to negotiate and gently dilate urethral strictures, establish a tract for catheter or guidewire placement, and confirm lumen patency prior to cystoscopy, instrumentation, or urethral surgery. The two sizes accommodate stepwise up-sizing without changing instruments, reducing instrument exchanges during short procedures.

Design & Configuration

The straight, double-ended geometry with two French-calibrated diameters permits predictable, incremental dilation in the anterior urethra. Tapered, smooth tips minimize mucosal trauma and provide tactile feedback to the operator for safe negotiation of narrowing. A single-piece, straight shaft preserves rigidity for controlled advancement while remaining slender enough to allow concurrent placement of small-caliber catheters or guidewires when needed.
