[Wall-stent for treatment of bulbar urethral stricture and DSD in spastic bladder]

Since may 1989 a urethral Wallstent has been used for the treatment of short urethral strictures and for DSD in paraplegic patients with reflex bladder activity. Forty-nine patients have now been followed-up, which exceeds the 6-month margin. Out of these, 25 suffered from a short stricture of the bulbous urethra and 24 had spastic bladders with severe DSD. Eighteen of the 25 patients with strictures had previous unsuccessful direct vision urethrotomies; 17 in the DSD group had undergone failed sphincterotomies. In all but 2 cases the infravesical obstruction could be treated effectively solely by stent implantation. The results obtained equal those of a well-performed end-to-end anastomosis of the bulbous urethra or a 12, o'clock sphincterotomy.
