“…This upward trend may partly be a reflection of the innovative expansion in the field as it blossomed. Similar exponential trends have been noted elsewhere in scientific literature, however, which has been attributed in large part to the introduction of the Internet as well as increased access to publications through the introduction of open‐access journals …”

“…The impact index was then calculated for each manuscript. This is a recently described concept that allows adjustment of the citation count by the number of years since publication . This novel metric was developed to address the hypothesis that older publications would have a higher potential citation count due to a longer exposure to the scientific community since publication, and thus longer availability for citation.…”

“…This novel metric was developed to address the hypothesis that older publications would have a higher potential citation count due to a longer exposure to the scientific community since publication, and thus longer availability for citation. The index is obtained by dividing the number of years since publication by the number of citations, multiplied by

100 [(\frac{Year since publication}{Number of citations}) \times 100],

with lower indices indicating higher impact …”

“…One such variable is the time elapsed since publication, given that papers that are published earlier have more temporal exposure and could have more citations because of availability rather than importance of findings. As a result, the impact index has been recently described, which allows for adjustment of citation counts based on time since publications, thus yielding a more objective measure of the impact of publications …”

“…As a result, the impact index has been recently described, which allows for adjustment of citation counts based on time since publications, thus yielding a more objective measure of the impact of publications. 8 As a relatively new analytical tool, the objective of the present study was to critically analyze the literature, by performing a bibliometric analysis of the 200 most-cited pediatric RT manuscripts, describe their basic characteristics, determine their impact index and citation counts, and perform visualization and citation mapping to understand their various interrelationships.…”

Introduction Pediatric renal transplantation has been heavily published since the 1950s. Herein, we describe the bibliometrics and impact of the 200 most‐cited pediatric renal transplantation manuscripts. Methods We identified pediatric renal transplantation publications from 1900 onwards. Year, citations, h‐index, geographic origin, impact factor, topic, and design of the 200 top‐cited papers were extracted. Impact index was calculated, adjusting for citation volume and time since publication. Results Of the top 200 papers, mean citation count was 80 ± 40, impact factor 3.9 ± 3.7, h‐index 35 ± 20, and impact index 25 ± 13. Studies were mostly retrospective (31%) or observational (32%). Most papers originated from the United States (58%), Germany (9%), and Italy (6%), which did not correlate with citation counts. Transplantation (18%), Pediatric Nephrology (16%), and American Journal of Transplantation (11%) had the highest publication volume, which did not correlate with citation count. The main topics were medical renal disease, drug monitoring, compliance, and viruses. Most of the top‐cited papers (179; 90%) were published after 1991. The difference in the number of times cited between papers published before and after 1991 was insignificant (75 ± 24 vs 80 ± 42; P = 0.59). There was a difference in impact index for the same period (48 ± 15 vs 22 ± 10; P < 0.01). Conclusions The most‐cited papers were concentrated in three journals, but the top three cited papers were published elsewhere. Recent publications were more cited with a higher impact than older papers. Despite the importance of surgery in transplantation, there is a paucity of high‐impact papers on this topic.

Aims: Electrical neuromodulation of bladder function has been extensively investigated in the literature. To date, there has been no characterization of the field, and there is a lack of bibliometric literature to guide future studies. We directed this scientometric analysis to characterize the distribution, characteristics and relationships of the field, with subanalysis of top 100 articles. Methods: The Web of Science Core Collection of the Thompson Reuters Web of Science was searched and analyzed to determine distributions and characteristics of clinical research investigating electrical neuromodulation in bladder dysfunction. Field citation and coauthorship networks were mapped, and recent citation bursts of the past decade are described. The top 100 cited articles were categorized, with level of evidence rating system applied. Results: A total of 872 articles published from 1949 until October 2020 were included in field analysis. Europe demonstrated the highest continental productivity within field (n = 539, 61.81%), and the United States the top nation (35.55% of field, 39.24% of top 100 articles). The Journal of Urology has historically published the most articles in the field (n = 150, 17.20%), and top 100 articles (n = 41, 40.20%). Top 100 articles reported studies of neuromodulation effects via sacral neuromodulation (n = 59); of non-neurological bladder dysfunction (n = 72); urinary incontinence (n = 92), frequency (n = 73) and urgency (n = 68) symptomology. Conclusions: Analysis of electrical neuromodulation of bladder dysfunction literature reveals historical development, core research clusters and relationships, and an increase in publication activity over past decades.
