Bulbar Stent (BUS)

Stents are grossly under-utilized in recurrent urethral strictures. There is no adequate solution for the treatment of recurrent urethral strictures other than palliative measures such as repeated dilations or optical urethrotomy. Reconstructive urethral surgery which can be successful only in the hands of experts. Studies showed that after optical urethrotomy, temporary stents left indwelling for a period of 12-14 months can prevent recurrent stenosis in up to 70% of patients.


Allium's Bulbar Stent is designed specifically for the treatment of recurrent strictures along the bulbar urethra. They will be the new therapeutic tool in the hands of the urologist who is not an expert in urethral surgery but has a case-load of recurrent urethral stricture patients to be treated. Differing from previous stents, they are large in caliber to match the contours of the bulbar urethral lumen. The main body acts as a mold to allow forming a large urethral lumen. The dynamic sphincteric segment prevents sphincteric dysfunction that may cause incontinence. The Allium Bulbar Stent is intended for temporary use and is designed to be removed easily and safely even after long indwelling periods.
