Although metallic stents offer an alternative to traditional polymer stents, long-term data on their efficacy, particularly for newer devices, are limited. This study evaluates the safety and efficacy of a novel, domestically produced thermally expanding nickel\u2013titanium alloy stent (Fulbright\n                      <jats:sup>\u00ae<\/jats:sup>\n                      ) in treating various ureteral strictures.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A prospective, single-center study was conducted between August 2024 and September 2025. Consecutive patients with ureteral strictures of diverse etiologies (e.g., stone-related, postradiation, iatrogenic, idiopathic) were enrolled. All participants underwent implantation of the thermally expanding nickel\u2013titanium alloy stent (Fulbright). Primary outcomes included technical success, stent patency, and changes in renal function parameters (serum creatinine, estimated glomerular filtration rate (eGFR), hydronephrosis volume) assessed during follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 21 patients (representing 23 ureteral units) were included.

The primary endpoint of an effective decompression was achieved in 87.0% of cases over a median follow-up of 5.0 months (interquartile range [IQR] 2.0\u20136.0). Postoperative renal function improved significantly, with serum creatinine levels decreasing from a median of 95.0 \u03bcmol\/L (IQR 73.0\u2013126.0) to 84.0 \u03bcmol\/L (IQR 68.0\u2013115.0) (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001).
