During the past quarter century there has been a renaissance of interest in the use of peritoneal dialysis as the primary dialytic modality for the treatment of children with end-stage renal disease (ESRD). The development of continuous ambulatory peritoneal dialysis (APD) has facilitated the provision of prolonged dialysis to infants, children and adolescents and has provided pediatric nephrologists worldwide with a real opportunity to administer effective dialysis therapy to all patients afflicted with ESRD. It has been more than a decade since the initial publication of CAPD/CCPD in Children. In the interim, a great deal of clinical experience with patients receiving peritoneal dialysis has been accumulated and research efforts have substantially increased our understanding of the technique. Therefore, we felt that a second edition of CAPD/CCPD in Children was propitious to update the advances of the past decade.
