Publication landscape of Posterior urethral valve- A scientometric study

      Summary

      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.

      Methods

      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.

      Results

      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).

      Conclusion

      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).
