The aim is to analyze by physical\u2013chemical characterization of the stent after use and to evaluate the material performance in this human <jats:italic>in vivo<\/jats:italic> case study. Six Resonance\u00ae metallic stents (Cook Ireland) were inserted in six patients for 6, 10, 11, 12, 24, and 36 months. The stents were then collected and studied by Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectroscopy (EDS), gaining information about the metal stent surface and the amount and nature of the formed encrustation. The stents were all draining adequately, despite the presence of the bacterial biofilm layer in all stents. This layer was more dense and compact as the indwelling time increased. Some slight precipitation of inorganic compounds, such as brushite and calcium oxalate was observed. No epithelial tissue in growth was recorded. These preliminary results with Resonance\u00ae metallic ureteral stents suggest the feasibility of a long\u2010term approach in patients with chronic ureteral obstruction. The durability of the metal stent, the lack of epithelial tissue ingrowths and limited pain or discomfort to patients were proven over long time periods. The long\u2010term use of these stents is therefore feasible, avoiding the continuous exchange of the stent, decreasing hospital costs and increasing the quality of life of patients affected by malignant pelvic tumors. \u00a9 2010 Wiley Periodicals, Inc.
