Objective: To evaluate the global scientific output, collaboration patterns, influential contributors, core publication sources, and thematic trends in urethroplasty research through a comprehensive bibliometric analysis of the literature published between 2000 and 2024.Materials and Methods: This descriptive bibliometric study used the Web of Science Core Collection database. English-language articles and reviews published in the Science Citation Index Expanded between January 1, 2000, and December 31, 2024, were included. Publication and citation data, authors, countries, institutions, journals, and keywords were extracted. Analyses were performed using bibliometrix in R and VOSviewer to assess publication trends, collaboration networks, source patterns, keyword co-occurrence, and thematic structure. Bradford’s law was applied to identify core journals.Results: A total of 3661 publications from 489 sources were analyzed. The annual growth rate was 5.47%, the average citation per document was 16.42, and the mean document age was 9.98 years. Guido Barbagli was the most productive author, while the United States led in both publication output and citation count. China and India also showed high research productivity. Urology and Journal of Urology were the most productive journals. Collaboration analyses revealed prominent author- and country-level research clusters. Keyword and thematic analyses identified urethroplasty, urethral stricture, and hypospadias as core topics, with graft use, reconstructive techniques, outcomes, and recurrence emerging as major research themes.Conclusion: Urethroplasty research is concentrated around a limited number of influential authors, institutions, countries, and core journals, while continuing to expand in thematic scope and collaborative structure.
