国产双端支架烟威地区首例手术成功

Core Viewpoint - The successful placement of the first dual-end new type of thermally expanded nickel-titanium alloy stent in the Yantai region marks a significant advancement in medical technology, improving treatment for ureteral strictures and enhancing patient quality of life [1][2] Group 1: Medical Technology Advancement - The new nickel-titanium alloy stent effectively supports the narrowed ureteral area, reduces stone shell formation, and extends stent retention time while minimizing urinary tract irritation symptoms [1] - This stent is the first domestically produced ureteral stent that can be retained long-term, featuring a segmental design that precisely covers the narrowed area without affecting ureteral peristalsis [1] - The metal stent offers high support strength and is less prone to deformation, providing better internal drainage and structural assurance for long-term retention [1] Group 2: Economic and Quality of Life Benefits - The introduction of the domestic thermally expanded nickel-titanium alloy stent alleviates the financial burden on patients caused by high-priced imported stents, enhancing treatment outcomes and patient quality of life [1] - The metal ureteral stent system can be retained long-term, avoiding issues associated with frequent replacements, such as bladder irritation and poor drainage, thus lowering medical costs and increasing health economic value [1] - The stent's tight spiral structure provides strong radial support, reduces complications like bladder irritation and reflux, and is easy to install and remove, ensuring a safe and smooth surgical process [1]
