Resumen:
Introduction & Objectives: Treatment of urethral stricture using the Urolume™ urethral stent (American Medical
Systems, Minnesota) was approved by the Food and Drug Administration in 1988 and distributed in many
countries until 2011. Memokath™ (Pnn Medical, Denmark) is a thermo-expandable biocompatible
endoprosthesis made of nitinol that is currently used for recurrent bulbar urethral stricture. This study evaluates
the role and success rate of urethral reconstruction in patients with urethral stent and recurrent stricture.
Materials & Methods: A retrospective multicenter study was conducted among different institutions with highvolume
urethral reconstruction using a board-approved database. Factors analyzed included: stricture and
stent length, time between stent and urethroplasty, age, mode of stent retrieval, type of urethroplasty,
complications and baseline and post-urethroplasty voiding parameters. Successful outcome was defined as
standard voiding, without need of any postoperative procedure.
Results: Fifty-six patients were included. Stent was removed at the time of urethroplasty in 54 patients (4 endoscopically, 28 full-segment excision
and 22 longitudinal section and explant o...
