title: The "Wallstent": a new stent for the treatment of urethral strictures.
abstract: Ten patients have been reviewed in whom urethral stents were implanted for treatment of urethral stricture. Their urethral strictures had been treated with a median of 4.2 endoscopic urethrotomies under direct vision without success. The patients were first treated with optical urethrotomy, and dilatation to 30 F--after which the stents were inserted under direct endoscopic control. A total of 12 stents were inserted. All patients had a 30 mm stent inserted first, and two patients had an additional 20 mm stent inserted because of recurrent stricture at the distal or proximal end of the first stent. One patient had a urethrotomy 12 months after insertion of the stent because of a short recurrent stricture at its distal end. The median length of follow up was 24 months. The median preoperative maximum flow rate was 6.5 ml/s, and the median postoperative maximum flow rate was 20.3 ml/s. Half the patients had postmicturition dribbling postoperatively. The stents were covered with epithelium after 6-18 months, most between 12 and 18 months.
