Stents are being used more frequently 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 in the hands of experts has a failure rate of 20%-25%. Studies showed that after an optical urethrotomy, temporary stents left indwelling for a period of 12-14 months can prevent recurrent stenosis in up to 70% of patients. 



The Allium BUS stent for bulbar strictures is designed specifically for the treatment of recurrent strictures along the bulbar urethra. 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 or long-term use of up to 3 years and is designed to be removed easily and safely even after long indwelling periods.
