Objective: A urethral stricture is the narrowing of the urethra caused by scar formation. The etiologies include infection, trauma with total urethral disruption, and iatrogenic procedures. The impact of urethral stricture diseases is very high. Several kinds of endoscopic procedures have become available for managing the disease. Among them, complete obliteration of the urethra during endoscopic procedures remains a challenge for surgeons. We describe a modified procedure in which laser urethrotomy was guided under the light source from an antegrade flexible cystoscope for treating a short completely obliterated urethra. This procedure is indicated if the obliterated segment is less than 10 mm because longer strictures may increase the chance of extra false lumen formation and bleeding.Materials and Methods: Forty-three male patients who underwent optical urethrotomy for urethral strictures at Kaohsiung Municipal Ta-Tung Hospital (Kaohsiung, Taiwan) between March 2013 and January 2015 were induced in the study. Five of these patients were diagnosed as having complete urethral obliteration.Results: In all five patients with a completely obliterated urethra, retrograde laser incision was performed successfully. Three patients had total bulbar urethral obstruction and two had penile obstruction. All patients experienced improved urination after the procedure.Conclusion: Our preliminary data showed that our modified method for treating a completely obliterated urethra yielded satisfactory results. Long-term follow-up and large-scale studies should be conducted to better examine technique efficacy; however, our current results regarding the simple modification of endoscopic urethrotomy seem promising
