Ureteral stent (US) is vital in managing ureteral obstruction, ensuring drainage, and providing structural support. Despite extensive research, a comprehensive synthesis of findings is lacking. This study employs bibliometric analysis and visualization tools to examine 2,994 articles from the Web of Science (1975-2024), identifying key researchers, institutions, countries, and trends. Results indicate a rising publication trend, particularly in the last five years, with the United States leading in output and centrality. The University of California System emerged as the top institution. Key journals and bridging keywords such as "complication" and "ureteral obstruction" (centrality > 0.1) highlight critical research areas, including surgical interventions, iatrogenic injury, and stent failure. Clustering revealed hotspots such as intrarenal surgery, ureteropelvic junction obstruction, stent-related symptoms, and benign ureteral obstruction. Current research focuses on guideline development, outcome evaluation, prevalence studies, and complications such as sepsis. This analysis provides insights into US research trends, guiding future innovation and topic selection in the field.
输尿管支架（US）在处理输尿管梗阻、确保引流以及提供结构支撑方面至关重要。尽管进行了广泛研究，但仍缺乏对研究结果的全面综合。本研究采用文献计量分析和可视化工具，对来自科学网（1975 - 2024年）的2994篇文章进行分析，确定关键研究人员、机构、国家和趋势。结果表明发表趋势呈上升态势，尤其是在过去五年，美国在产出和中心性方面领先。加利福尼亚大学系统是排名第一的机构。关键期刊以及诸如“并发症”和“输尿管梗阻”（中心性>0.1）等桥梁关键词突出了关键研究领域，包括手术干预、医源性损伤和支架失效。聚类分析揭示了肾内手术、输尿管肾盂连接部梗阻、支架相关症状和良性输尿管梗阻等热点。当前研究集中在指南制定、结果评估、患病率研究以及败血症等并发症方面。该分析为输尿管支架研究趋势提供了见解，指导该领域未来的创新和选题。
