Methods 26 patients with urethral stricture or obliteration were treated with transurethral urehrotomy from August 1993 to October 1999.All patients underwent transurethral urethrotomy with the contact Nd:YNG laser delivered with the 600μm bare fiber at 30 to 50W.The urethrotomy was guided only by a metal sound introduced through the suprapubic tract. Results Satisfactory voiding was achieved after catheter removal in all patients.26 patients were followed up for 6～24 months.Normal micturation was observed in 24 patients(92.3%).Recurrent stricture occurred in 2 patients (7.7%).Of the 2 patients one needed periodical urethral dilatation and the other required repeat internal urethrotomy.The only complication was epididymitis in 2 patients.Urethroscopy was performed in 18 patients 4～12 weeks after catheter removal.Urethrotomy revealed a widely patent uretha with complete epithelialization at the site of the previous urethrotomy. Conclusions Transurethral urethrotomy with the contact Nd:YNG laser is a safe and effective treatment for urethral stricture and obliteration.The rate of stricture recurrence is relatively low.Complications not frequeutly seen and satisfectory short-term effect can be obtained.
