Endourethral prosthesis. Current indications, materials and types of prosthesis

OBJECTIVES: To update the topic of endourethral prosthesis for the treatment of recurrent urethral stenosis comprehensively, focusing on current indications, materials and types of prosthesis in use nowadays. METHODS: We used the PubMed database (1995-2013) with the terms "endourethral", "prostheses", "endourethral prosthesis" and selected the most relevant articles for this publication. RESULTS: Results were variable depending on the series published, with great differences among them. They are not homogeneous groups, so they are not comparable to each other. CONCLUSIONS: Endourethral prostheses have an important role today in the treatment of recurrent urethral stenosis. More studies are required, with longer follow up to be able to establish which one is the one with the lowest complication rates and best results in terms of urethral caliber and symptom questionnaire.
