[Entero-vesical fistula in primary lymphoma of the small intestine].

The introduction of self-expandable urethral endoprotheses for the management of relapsing urethral stenosis has required the development of a minimally invasive therapeutical approach of widespread acceptance by the urological community. The reason for its success is the simplicity of implantation and the low rate of complications up to date. This paper reports on a patient carrying a ¿Urolume¿ urethral endoprothesis for a relapsing bulbar urethral stenosis, which two years after implantation presents re-stenosis secondary to endoluminal inflammatory tissue growth. After two failure endoscopic resections, endoscopic removal of the prosthesis was required. Currently the patient carries a ¿Urocoil¿ spiral endoprosthesis to avoid tissular reaction. The therapeutical aspects found in the literature are reviewed, emphasizing the need of follow-up to detect complications, to improve indications and to select those patients that may be candidates for this treatment.
