Introduction:
This study aimed to perform a bibliometric analysis of academic research on uremia, identifying research hotspots, development trends, and international collaboration networks in this field. Methods. Relevant publications related to uremia were retrieved from Web of Science database. Bibliometric analysis was conducted using R software. Co-occurrence analysis of keywords, co-citation network analysis, and author/country collaboration analysis were performed to explore research focuses and academic influence.
Results:
From 2021 to 2022, research on uremia mainly concentrated on traditional areas such as chronic kidney disease, hemodialysis, and patient management. Since 2023, the focus has gradually shifted toward emerging topics including plasma biomarkers, inflammation mechanisms, and precision patient care. Co-citation network analysis revealed that studies related to chronic kidney disease and hemodialysis had the strongest academic influence, while research on inflammation and uremia also occupied central positions in the network. International collaboration was most active in China, the United States, and Europe, reflecting a trend toward cross-border and interdisciplinary research. Meanwhile, keywords such as gut microbiota, metabolomics, and precision medicine are increasingly frequent, highlighting new research frontiers.
Conclusion:
This study demonstrates that uremia research is shifting from traditional areas such as chronic kidney disease and hemodialysis toward emerging themes including inflammation, biomarkers, and patient management. These findings provide objective evidence of research hotspots and trends in uremia and underscore the importance of enhancing international and interdisciplinary collaboration.
