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).
