Abstract

Background: Systematic reviews and meta-analyses are essential for evidence-based urology practice. Despite their importance, no comprehensive assessment of their evolution exists, limiting understanding of research priorities. This bibliometric analysis examines systematic reviews and meta-analyses in urology, analyzing publication trends, influential works, and collaboration networks to guide future research. Methods: In this bibliometric study, a comprehensive search of the Scopus database was conducted until January 2024, focusing on English-language systematic reviews and meta-analyses in urology. Bibliometric data were analyzed using Excel, VOSviewer, and Scimago Graphica to examine publication trends, citations, collaborations, and research themes. Results: Analysis of 9006 publications (55.4% open access) showed exponential growth from 1987 (n = 1) to 2024 (n = 1025). The top 50 cited papers focused mainly on urological oncology (uro-oncology), surgical outcomes, and diagnostic imaging. European Urology emerged as the leading journal, showing strong bibliographic coupling with other specialty urological journals. Term co-occurrence analysis revealed 5 major clusters: (1) drug efficacy in prostatic hyperplasia; (2) cancer risk and genetic studies; (3) treatment modalities in urological cancers; (4) surgical complications; and (5) diagnostic accuracy in prostate cancer. The United States, Italy, and the United Kingdom demonstrated the strongest international collaboration networks, with European countries showing robust research partnerships. Conclusion: Urological evidence synthesis shows particular emphasis on uro-oncology, surgical outcomes, and diagnostic imaging, reflecting the evolution of evidence-based urological practice. Future research should focus on expanding international collaborations, addressing emerging diagnostic technologies, and developing standardized methodologies for evidence synthesis in urological practice. © 2025 Elsevier B.V., All rights reserved.
