Significant obliteration of the urethral lumen after Wallstent implantation.

The permanently implanted self-expandable urethral stent (Wallstent) has found increased use in patients with recurrent urethral strictures because of its simple implantation technique. To date there have been no reports of serious complications. At 6 weeks after stent implantation our patient had complete luminal obstruction. This complication demonstrates the need for short-term controls after implantation of a urethral stent.
