Abstract
The permanent Urolume™ Wallstent has been used for the relief of bladder outlet obstruction (BOO), detrusor—external sphincter dyssnergia (DESD), and recurrent bulbar urethral strictures. Because of its woven construction, it allows ingrowth of urothelial tissue, resulting in complete epithelialization by 6 to 12 months. Certain risk factors are associated with poor epithelialization that may lead to hyperplastic tissue growth and occlusion of the urethral lumen. We review the literature and discuss the 5-year results of the North American Multicenter Urolume™ Trial with regard to epithelialization, hyperplastic tissue growth, and treatment of hyperplastic growth.
