    【Abstract】 Objective To summarize and evaluate the endourethral surgery for urethrostenosis.Methods 26 patients suffering from urethrostenosis were treated by interal urethrotomy. Some experiences were learned and summed up.Results The success rate in this series was 96%(25/26). 1 patient was treated by opening operation because of the long urethrostenosis and unable to posting the guiding silk.25 patients have been followed up for 1～6 years. Satisfactory voiding has been achieved in all.Conclusion Endourethral surgery is safe and efficient treatment for urethrostenosis.The success of the treatment depends on a few key points. Firstly,the stenosed segment of urethra should be thoroughly understood .Secondly,during operation,the stricture should be incised along the true urethra tract with cold-knife.The scar should be incised completely. Finally,in the post-operation period,infection should be prevented and the urethral catheterization should be managed appropriately. ......
