[Endoscopic treatment of urethral strictures]. / Traitement endoscopique des sténoses de l'urètre.

ABSTRACT

The present article reviews the literature regarding the endoscopic treatment of urethral strictures. Only few prospective randomised clinical trials with sufficient power have been performed and most of the literature provides evidence of only level 3 and 4. Since length, location, extent and calibre of the urethral stricture have an important impact on prognosis, diagnosis and the role of ultrasonography are discussed. Pathophysiology of wound healing is discussed in relation to urethrotomy, as it explains the outcomes of the procedure. Operative techniques using cold knife and laser, use of endoprostheses, indications, complications, results and postoperative management are described. The possible role of urethral catheters, hydraulic dilatations and corticosteroid applications are discussed.
