Filiform urethral bougie

A filiform urethral bougie is a slender, flexible surgical tool used to navigate and widen narrow sections of the urethra, often caused by strictures. Clinicians insert it manually—either directly or through a catheter—to gently guide it through the obstruction, often shaping its tip to improve passage. The device helps restore urine flow by gradually dilating the urethral passage, reducing symptoms like pain or urinary retention.

These devices are typically single-use and made from materials like plastic or PVC, with a threaded metal section for attachment to other tools. Regulation varies by jurisdiction, but they are generally classified as surgical instruments and must comply with medical device standards. Availability depends on local healthcare systems, often supplied as part of urological procedure kits.
