To assess the global research landscape in the field of Posterior urethral valve (PUV), a scientometric study was conducted to determine the quantity and quality of the research output and get insight into the key research areas and pattern of collaboration in the research community.
Primary data was acquired from the Scopus® database. Various parameters like the total research productivity, citations, citations per publication, citations per year, citations per publication per year, the scientific output of countries, institutions, authors, and journals were calculated. Key research areas were inferred by examining the top-cited articles (citations >150). Collaborative maps were generated by calculating co-authorship links amongst countries and authors using VOSviewer software.
One thousand seven hundred fourteen results were found published from 1913 to 2019, receiving a total of 27,253 citations, authored by 5138 authors from 125 countries. The top three countries were the United States of America (USA), India, and the United Kingdom (UK). The leading institutes were the Children's Hospital Boston, USA (n = 48), All India Institute of Medical Sciences (AIIMS, Delhi), India (n = 38), and Great Ormond Street Hospital, UK (n- = 27). The journals which published the most articles on PUV were the Journal of Urology (n = 278), Journal of Pediatric Urology (n = 121), followed by Urology (n = 86). Leading authors were Glassberg, K. L and Bajpai M (n = 17, each), Canning DA & Kajbafzadeh, AM (n = 16, each), followed by Peters CA with 14 manuscripts. The top-cited documents (n = 10) received 2104 citations and were published between 1986 and 2010. The key areas of interest found were "long-term outcomes" (n = 4) and "fetal surgery" (n = 2). The most productive countries were also the most collaborative countries (the USA and UK).
In the research landscape of PUV, the USA, Children's Hospital Boston, and Glassberg, K. L, along with Bajpai, M were the top contributors in terms of the country, organization, and authors, respectively. The "Journal of Urology" and "Pediatric Nephrology" stands out in terms of bibliometric parameters considered. The hotspot topics based on the number of citations received were "long-term outcomes" and "fetal surgery" in PUV. The most productive countries were also the most collaborative countries (the USA and UK).
为评估后尿道瓣膜（PUV）领域的全球研究状况，开展了一项科学计量学研究，以确定研究产出的数量和质量，并深入了解关键研究领域以及研究群体中的合作模式。
从Scopus®数据库获取原始数据。计算了各种参数，如总研究生产力、引文、每篇出版物的引文、每年的引文、每年每篇出版物的引文、各国、各机构、各作者和各期刊的科研产出。通过审查被引频次最高的文章（引文>150）推断关键研究领域。使用VOSviewer软件通过计算国家和作者之间的共同作者链接生成合作图谱。
发现1913年至2019年发表了1714篇研究成果，共获得27253次引文，由来自125个国家的5138名作者撰写。排名前三的国家是美利坚合众国（美国）、印度和英国。领先的机构是美国波士顿儿童医院（n = 48）、印度全印度医学科学研究所（AIIMS，德里）（n = 38）和英国大奥蒙德街医院（n = 27）。发表关于PUV文章最多的期刊是《泌尿学杂志》（n = 278）、《小儿泌尿学杂志》（n = 121），其次是《泌尿学》（n = 86）。领先作者是格拉斯伯格，K.L和巴杰帕伊，M（各n = 17），坎宁，D.A和卡吉巴法扎德，A.M（各n = 16），其次是彼得斯，C.A，有14篇手稿。被引频次最高的文献（n = 10）获得2104次引文，发表于1986年至2010年之间。发现的关键关注领域是“长期结果”（n = 4）和“胎儿手术”（n = 2）。研究产出最多的国家也是合作最多的国家（美国和英国）。
在PUV的研究领域中，就国家、机构和作者而言，美国、波士顿儿童医院以及格拉斯伯格，K.L和巴杰帕伊，M分别是最大贡献者。就所考虑的文献计量参数而言，《泌尿学杂志》和《小儿肾脏病学》最为突出。基于获得的引文数量，PUV中的热点主题是“长期结果”和“胎儿手术”。研究产出最多的国家也是合作最多的国家（美国和英国）。
