Abstract: Background: In the past decade, scientific research has developed rapidly in China, but the growth seems to vary widely between different disciplines. In this study, we aimed to compare the quantity and quality of publications in urology and nephrology journals from USA, China and Japan. Methods: Journals listed in the “Urology and Nephrology” category of Science Citation Index Expanded subject categories were included. Scientific papers in these journals written by researchers from USA, Japan and China were retrieved from the “PubMed” and “Web of Knowledge” online databases. Results: The annual number of total scientific articles increased significantly from 2001 to 2010 in China, and has ranked second in the world since 2006. In the field of urology and nephrology, the annual number increased significantly from 2001 to 2010 in USA and China; but not in Japan. The share of articles increased significantly over time in China, decreased significantly in Japan, and remained unchanged in USA. In 2010, USA contributed 32.17% of the total world output in urology and nephrology field and ranked 1st; Japan contributed 5.19% and ranked 5th; China contributed 3.83% and ranked 9th. Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA>Japan>China, p Japan(6704)>China(2233), p Japan>China, p
