Abstract: 【Abstract】Objective To evaluate the current research status and research hotspots of peritoneal dialysis in the past decade. Methods In the Science Citation Index Expanded database of the Web of Science, this study applied the relevant researches on peritoneal dialysis from 2010 to 2019 to extract and analyze according to journals, authors, research institutions, keywords by bibliometrics and VOSviewer software. We analyzed the hotspots and development history of the research field of peritoneal dialysis by visual display. Results A total of 6,864 studies were retrieved. In general, the output of peritoneal dialysis research has fluctuated in the past decade. Number of studies on peritoneal dialysis ranked top 1 country is the United States, and the publication volume, journal distribution, frequency of citations, H index and fund-funded output of peritoneal dialysis research in the United States are all ranked in the forefront. The research on peritoneal dialysis is developing rapidly in China, and the research institutions and authors are mainly concentrated in our country. But domestic research institutions have little cooperation with related international institutions, and the cooperation between research authors is relatively scattered. The hotspots of peritoneal dialysis research mainly focus on the evaluation of treatment prognosis, pathological mechanisms, complications, dialysis quality and quality of life. Conclusions Using bibliometric methods，we can get a clearer and more intuitive understanding
of the current of global research status and hotspots of peritoneal dialysis.
