[Endoscopic treatment of urethra stenosis by super-impulse plasma electrode].

Objective: To evaluate the effect of internal urethrotomy with Super-impulse plasma electrode (SIPE) method on urethral stricture. Methods: A total of 48 patients clinically diagnosed as having urethral stricture were hospitalized and treated with SIPE under the endoscope from February 2005 to August 2006. The patients' symptoms and clinical signs were compared before and after the treatment. In addition, techniques in operating SIPE were discussed. Results: Of the 48 patients, 46 were cured and 2 experienced recurrence after the operation. A 3-18 months follow-up revealed no complications. Conclusion: SIPE under the endoscope is safe and effective in the treatment of urethrostenosis. It is easy to handle and the results are satisfactory.
