Die endoskopische Behandlung der Harnröhrenstriktur

Abstract

Great progress has been seen in the treatment of urethral strictures since the first endoscopic urethrotomy was performed in 1893 by Felix Martin Oberländer in Dresden, Germany. With the introduction of endoscopic laser therapy and the variety of urethral reconstruction methods other ways to treat this important urologic entity became available. Despite this progress, urethrotomy still represents the preferred treatment concept for primary, short and bulbar urethral strictures. In this study we performed a 2-year retrospective analysis of 20 patients undergoing primary endoscopic urethrotomy by single bulbar or penile narrowing. A high incidence of recurrence was seen in 70% of the patients. Nevertheless, direct vision urethrotomy represented a safe and effective transitory method to treat these patients. Moreover, 80% of the patients preferred, in cases of recurrence, a repeated urethrotomy as the treatment of choice. Although the long-term results evidence high relapse rates after the first and second procedures, there have been no sufficient data in the literature which support the use of other methods. Furthermore, primary endoscopic management of urethral strictures remains a simple, safe, and cost-effective procedure that should be indicated before more invasive approaches are taken to provide relief to these patients from this limiting problem.
