Microbiome in Lower Urinary Tract Symptoms (LUTSs): Mapping the State of the Art with Bibliometric Analysis

Background: The main objective of this study is to provide the first characterization of the current research field of the clinical microbiome in LUTSs. Methods: First-of-its-kind scientometric insight into the historical development and structural state of the discipline is provided by a field analysis, mapping, and sub-analysis of articles for future research. On 22 December 2022, the entire Scopus database was searched without language or date restrictions. Search terms included “Chronic prostatitis”, OR “Interstitial cystitis”, OR “Lower urinary tract symptoms”, OR “Lower urinary tract dysfunction”, OR “Overactive bladder”, OR “Incontinence”, OR “Urolithiasis”, OR “Urothelium”, OR “Urine”, OR “Urology”, OR “urinary disorder”, OR “Pathophysiology”, OR “Benign prostatic hyperplasia”, OR “Benign prostatic enlargement”, AND “Microbiota”, OR “Microbiome”, OR “Urobio-ma”, OR “Urobiota; microflora”. The author and institutional data were transformed using the analytical tool Biblioshiny (a Shiny app for Bibliometrix), which took into account variations in author spelling as well as institutional naming and subgroups. Results: The specified search strategy was able to locate 529 documents from 267 sources published from 1981 to 2022. The average number of years from publication was 4.59 years. The authors with the most publications were Wolfe AJ and Brubaker I. The top three most collaborative networks were Loyola University Chicago, Loyola University Medical Center, and the University of California San Diego. The most frequently occurring words among the 50 nodes were: human, humans, nonhuman, female, adult, article, microbiology, microflora, microbiota, and controlled study. Frontiers in Cellular and Infection Microbiology and the International Urogynecology Journal, followed by Nature Reviews Urology, were the top three most relevant sources in microbiome research in urology. Conclusions: One of the most crucial requirements for developing research policies and anticipating the scientific requirements of researchers is paying attention to the evolution of various scientific fields. Understanding research gaps and future needs in microbiome research in urology can be effectively understood by paying attention to the models, maps, and visualizations used in this research, which are the results of systematic analysis of scientific products in the most esteemed scientific journals in the world.
