Knowledge‑map Analysis of Ureteroscopy for Urolithiasis

Area of Science:

• Urology
• Bibliometrics
• Medical Technology Assessment

Background:

• Ureteroscopy (URS) is a globally recognized treatment for urolithiasis (kidney stones).
• Bibliometric analyses specifically on URS for urolithiasis are relatively scarce.
• Understanding research trends is crucial for advancing clinical practice.

Purpose of the Study:

• To conduct a bibliometric analysis of literature on URS and urolithiasis.
• To identify core research directions, developmental frontiers, and hotspots in the field.
• To provide valuable insights for urologists regarding research trends.

Main Methods:

• Literature search of the Web of Science Core Collection over the past two decades.
• Data compilation and analysis using CiteSpace and VOSviewer software.
• Identification of publication trends, keywords, leading authors, prominent journals, and contributing countries.

Main Results:

• 1,461 publications identified, showing consistent annual growth with a surge post-2010.
• "Ureteroscopy" and "calculi" were the most frequent keywords.
• Olivier Traxer (France) identified as a leading expert; The Journal of Urology published most frequently; Turkey is the most prolific country.

Conclusions:

• Four primary research hotspots identified: complication mitigation, treatment protocol standardization, stone type-based indication determination, and novel ureteroscopic lithotripsy techniques.
• The field demonstrates dynamic growth and evolving research interests.
• This analysis provides a comprehensive overview of URS research in urolithiasis management.
