Use of multiple Wallstents in treatment of bladder outlet obstruction

Of 23 patients being treated with the Urolume Wallstent for bladder outlet obstruction, 4--3 with anterior urethral strictures and 1 with benign prostatic hyperplasia--required two to four stents. When placing multiple stents, there should be enough overlap to prevent the opening of a gap as the stents expand and shorten over the ensuing weeks. Use of more than 1 stent is indicated when the stricture or the prostatic urethra is longer than 3 cm or when stricture recurs beyond the end of a previously placed stent.
