Introduction and Hypothesis

Urethral diverticulum (UD) is a complex condition with significant implications for patient quality of life. Despite increasing interest, gaps remain in understanding its etiology, optimal diagnosis, and long-term outcomes. This bibliometric analysis examines global research trends in UD to identify key themes and knowledge gaps.

Methods

A literature search was conducted in the Web of Science Core Collection on January 8, 2025, using the terms “urethral diverticulum” OR “urethral diverticula” OR (“urethra” AND “diverticulum”). English-language original and review articles published between 1970 and 2024 were included. Articles were manually screened for relevance. Bibliometric analysis was performed using Bibliometrix and VOSviewer to assess publication trends, citation impact, collaboration networks, and keyword co-occurrence.

Results

A total of 357 articles met inclusion criteria, with a slow annual publication growth rate (0.95%). The United States, China, and the United Kingdom were the top contributors, with low international co-authorship rates (5.6%). Most research focused on surgical management, especially diverticulectomy, with limited studies on conservative treatments or minimally invasive approaches. Key research themes included imaging techniques, surgical outcomes, and UD management in women, while gaps persisted in long-term patient-reported outcomes and standardized diagnostic protocols.

Conclusions

UD research remains underdeveloped with a predominance of surgical studies. Increased international collaboration and research on nonsurgical management, minimally invasive techniques, and long-term outcomes are needed to refine clinical guidelines and improve patient care.
