%X Objectives: To report the 2-years follow-up
of patients with bulbar urethral strictures treated with the new AlliumTM
Bulbar Urethral Stent (Allium BUS). Methods: The stent is a fully covered,
self-expendable, large caliber metal stent specially designed for the
treatment of bulbar urethral strictures. The stent is comprised of a coiled
super-elastic structure covered by a polymeric coating designed to prevent
mucosal hyperplasia. The indwelling time is 12 months, after which the stent
should have been removed. Sixty-four patients with recurrent bulbar stricture
were treated with Allium BUS in 3 worldwide centers. Results: All stents were successfully
inserted with no perioperative complications. In a median follow-up of 25.5
months, the mean maximal flow rate following stent insertion was significantly
higher compared to the pre-surgical flow rate (14 ml/sec vs 6.6 ml/sec, p <
0.0001). Longer indwelling time and shorter stricture length were significantly
related to success rate. The main complications were stent migration, stent
re-stenosis and urinary tract infections. Conclusions: The temporary placement
of the AlliumTM BUS showed encouraging results with long-term failure rate of
only 25%.
