Abstract: The work is a literature review. Residual kidney function (RKF) is one of the crucial indicators of mortality and quality of life in patients with chronic kidney disease. Residual renal function provides better control of hydration, blood pressure, clearance of substances with low and middleweight, anemia, Ca/P metabolism, chronic inflammation. However, approaches to preservation of RKF in dialysis patients have been studied not enough, the importance of RKF preservation is underlined. The wide range of predictors of RKF loss are presented in the article, approaches to measurement of RKF, the relationship between level and presence of RKF with survival and mortality of patients with CKD 5D were analyzed. The possibility of RKF preservation and extension using different approaches by correction of dialysis prescription were estimated. There is no standardized method for applying incremental hemodialysis in practice. Onceto twice-weekly hemodialysis regimens are often used randomly, without knowing the benefit for current patient or how to escalate the dialysis dose if RKF declines over time. It is important to change the HD/HDF prescription according to the range of RRF using objective data.
