Abstract

The most common form of replacement therapy for end-stage renal disease (ESRD) is hemodialysis, and the adequacy of hemodialysis is strongly associated with the quality of life and long-term survival of patients. Kt/V is currently one of the most important indicators for evaluating the adequacy of hemodialysis. There are many methods for measuring Kt/V, such as blood collection and measurement, dialysate measurement, bioresistive resistance, WinNonlin software analysis, and artificial intelligence. There are different views on the importance of Kt/V as an indicator of the adequacy of hemodialysis. This article provides a literature review of the various methods of measuring Kt/V and on different perspectives on Kt/V as an evaluation of hemodialysis adequacy.

Keywords: chronic kidney disease (CKD); dialysis adequacy; end‐stage renal disease (ESRD); maintenance hemodialysis (MHD); urea removal index (Kt/V).
