Endoscopic treatment of urethral stenosis is not an alternative to surgical therapy but is an ideal therapeutical partner. The limits of endoscopic resection lie in the lack of anatomopathologican and clinical knowledge regarding the long-term maintenance of stability of the urethral lumen that in every case the internal urethrotomy manages to create. In fact internal urethrotomy is capable of almost totally eliminating the urethral stenosis but with a higher incidence of relapse, even in the short-term. The complications of endoscopic therapy of urethral stenosis are the usual local complications and of mild seriousness. Among the most frequently noted are the swelling and/or peno-scrotal suffusion by incorrect routes, and post-operative urethraemorrhagia. More rarely, but with serious effects, are purulent urethritis or sepsis. In our case list major complications such as priapism, cavernositis or septic shock were not noted. In conclusion endoscopic therapy of urethral stenosis is a simple technique, repeatable with low morbidity and is the best technique in the congenital 'ring'.
