OBJECTIVE: To determinate the efficacy in the treatment of ureteral estenoses after renal transplantation with metallic self-expandable stent. MATERIALS AND METHODS: From october of 1995 to april of 2002, 8 ureteral obstruction post renal transplantation have treated by means of implants of a metallic self-expandable stent (6 men and 2 women). The average time of pursuit was of 30 months (rank 2-53 months). In this work the severity and location of the estenosis are analysed, the method of implant of the stent, the permeability of the same one, the levels of creatinine pre and postimplant and the complications derived from the same one. RESULTS: The treatment was effective in the 100% of the patients (8/8), with an average reduction of the creatinine of 36% (rank 13,6%-59,6%). The complications were minimun and the hospital stay was short. CONCLUSIONS: In the patients with: chronic deterioration of the graft with short functional expectation, patient with high surgical risk and reestenosis after ureteral reimplantation by previous ureteral estenosis, the use of a metallic self-expandable stent, constitutes technique of election given its efficacy and low associate morbidity.
