[Placement technique of a permanent urethral endoprosthesis].

By taking into account the properties of this stent, which must eventually become completely epithelialized, it is important to clearly define its length so that its proximal and distal ends lie in healthy mucosa and the stricture must be dilated to allow maximum expansion of the stent. On the other hand, due to the severity of periurethral fibrosis, which can advance through the stent, this solution is contraindicated in the case of posttraumatic stricture or recurrence after urethroplasty. Apart from these contraindications, this is a rapid, sophisticated and effective procedure for which the current data of the literature are convincing.
