[Chronic kidney insufficiency in children].

Chronic kidney insufficiency (CKI) in children: Failure to thrive, feeding disorders and/or excessive thirst must evoke CKI in children. More than 50% of renal diseases in children with CKI are congenital or inherited. Major issues are growth, nutrition and renal osteodystrophy. Psychological and social management are crucial aspects of the therapeutic project. Peritoneal dialysis is the renal replacement therapy of choice, especially in children under 2 years, with an important risk of peritonitis. Kidney transplant, which can be performed in children more than 10 kg, is the best treatment of end-stage renal failure in children. Pediatric transplant specificities are increased risks of thrombosis, post-transplant lymphoproliferative disorders in EBV-negative recipients, and poor compliance to medication during adolescence.
