[A continuously revised problem: the treatment of stenosis of the male urethra]

This paper outlines the evolution experienced in the treatment of male urethral stenosis over the last 25 years, based on self experience and the review of relevant literature. Criteria justifying such evolution are illustrated including explanations and criticism of techniques from the primitive urethral "dilatation" to endoprothesis. Special emphasis is laid on the importance of pre-operative diagnosis and the need for adequate urethrographic examination which, very often, the urologist himself should perform in order to avoid interpretation mistakes and lamentable surprises during surgery. Finally, in view of all the above, a strategy of practical actuation is outlined.
