Lister Urethral Bougies 6/9 FG

Clinical Application

These small-caliber urethral bougies are intended for atraumatic calibration and negotiation of narrow urethral segments. The 6 FG and 9 FG sizes are commonly used when initial access through a constricted urethra is required, for pediatric or female urethral applications, or to guide a hollow catheter or dilator over a wire or trocar. They assist clinicians in assessing lumen patency and in staged dilation where stepwise increases in diameter are required.

Design & Configuration

The slender, tapered shaft and rounded atraumatic tip minimize mucosal trauma during insertion and help the device track smoothly through strictured or tortuous urethral segments. Offering two small French sizes in one configuration enables incremental calibration and controlled upsizing when moving to larger dilators or introducers. The straightforward design focuses on tactile feedback to the operator, allowing controlled advancement and confirmation of passage into the bladder or past a narrowed segment.
