title: Fluid overload and residual renal function in peritoneal dialysis: the proof of the pudding is in the eating.
abstract: McCafferty and colleagues report on a retrospective analysis in peritoneal dialysis patients in whom fluid status was assessed by multifrequency bioimpedance. During 12 months of follow-up, overhydration, as identified by an increased ratio of extracellular over total body water, was not associated with better preservation of residual renal function (RRF). These findings suggest that running patients 'wet' might not contribute to better preservation of RRF in peritoneal dialysis.
