Abstract：Objective: To explore the method of the urethral under cystoscopy to treat the urethrostenosis and to evaluate the curative effect of this method. Methods: The therapeutic data of the urethrostenosis in 20 cases admitted to our hospital from September 2010 to September 2012 were retrospectively analyzed. Of them, 11 cases had the history of lower abdominal open operation and all of them were admitted to hospital because of acute urine retention and failure to indwell catheter and urethral dilatation. All patients were further dilated with cystoscopy under direct vision of 19.5 F cystoscopy after the ureteral catheter dilatation. 16 F and 18 F catheters were indwelled for 1-2 weeks after operation, then the conventional regular dilatation was performed. Results: Operations were successfully performed and catheter was indwelled in 20 cases. Of them, the conventional urethral dilatation could be smoothly performed under the blindness and urine could swimmingly urinate after catheter was removed postoperatively 1 week. Postoperative follow-up for 3 months-2 years. Five cases of swimmingly urination needn’t treat again, the rest of patients could smoothly undergo regular urethral dilatation. Conclusion: The endoscope dilatation technique for treatment of urethral stricture has better effect, and can avoid urethral false passage, especially for patients with acute urinary retention with lower abdominal open operation history and can avoid risks of bladder puncture fistulation and the intestinal perforation.
