Comparative evaluation of CAPD and PD-plus effectiveness.

Decline in residual renal function in CAPD patients often leads to reduced overall solute clearances. Inadequate dialysis has been linked to malnutrition and increased morbidity and mortality rates. Achieving dialysis adequacy targets is often difficult by the conventional method of increasing CAPD exchange volumes. In comparison, substantial increases in solute clearances can be achieved with the use of automated peritoneal dialysis with large fill volumes and an extra daytime exchange.
