Abstract:
Endoscopic intraluminal implantation of a self expandable stent has been increasing in patients with recurrent urethral strictures because of its simple and relative safe technique. There has been a few reports concerning luminal obstruction after implantation of Wallstent. We have experienced 4 cases of urethral obstruction after variable period of Wallstent implantation in the treatment of traumatic urethral stricture. Herein the methods for treatment of urethral obstruction are discussed. The patients were managed with two different types of treatment. The first one was transurethral resection of granulation tissue inside Wallstent. The other is reinsertion of Wallstent inside the first one after transluminal resection of granulation tissue in patients with urethral obstruction occurring within 5 months after Wallstent implantation. Retrograde urethrography and urethroscopy after 3 months have demonstrated patency of urethra and epithelial covering of the implant. Our experience shows that in all 4 patients with traumatic urethral stricture have developed variable degrees of urethral obstruction after a variable period of wallstent implantation. Therefore, we consider that our method is one of the alternatives to treat urethral obstruction after wallstent implantation in patients with traumatic urethral stricture.
