ASSOCIATION OF ALTERNATIVE APPROACHES TO NORMALIZING PERITONEAL DIALYSIS CLEARANCE WITH MORTALITY AND TECHNIQUE FAILURE: A RETROSPECTIVE ANALYSIS USING THE UNITED STATES RENAL DATA SYSTEM-DIALYSIS MORBIDITY AND MORTALITY STUDY, WAVE 2

摘要

Background: Total body water (V) is an imprecise metric for normalization of dialytic urea clearance (Kt). This poses a risk of early mortality/technique failure (TF). We examined differences in the distribution of peritoneal Kt/V when V was calculated with actual weight (AW), ideal weight (IW), and adjusted weight (ADW). We also examined the associations of these Kt/V measurements, Kt/body surface area (BSA), and non-normalized Kt with mortality and TF.
