ABSTRACT
Chronic kidney diseases severely affects human health and quality of life.The end-stage renal disease (ESRD) patients require extensive blood purification treatments.Due to the limitations of methods,traditional dialysis treatments greatly limit the activity of the patients undergoing dialysis.Portable artificial kidneys can meet the diverse needs of these patients,and has become a new direction of research.There are two types of portable artificial kidneys,which are respectively based on hemodialysis and peritoneal dialysis,such as wearable artificial kidney (WAK) and bio-implantable artificial kidney (BAK).At present,preclinical experiments with artificial kidneys have achieved initial success,basically meeting treatment needs.Portable artificial kidneys are expected to achieve a mobile continuous dialysis treatment,reduce hospitalization and mortality in ESRD patients,save medical resources,improve the life quality of the patients,and make the patients return to normal lifestyles.The research status of WAK and BAK was reviewed,and their future developments were prospected.
