It will present the different databases/search engines available to clinicians and researchers and describe strategies to focus the search to one's particular needs. Indeed, databases/search engines used and search strategy should vary according to the goal of the research. If the aim is to address a clinical problem, the search should allow to identify a small number of most pertinent articles (high specificity); if the search is for research purposes, instead, it should ensure no meaningful articles are overlooked (high sensitivity).enPublisher Policyevidence based medicinepaediatric urologyliterature searchpediatric urologyArticle
