9. Intrinsic renal ESRD in neonates
Rare
Extremely poor prognosis
Renal replacement therapy not always recommended. As recently as 1998, only 40% of international pediatric nephrologists would offer dialysis to infants < 1 month
(J. Pediatr 1998, 133, )

12. Outcomes of dialysis initiated during the neonathal period for treatment of ESRD: a NAPRTCS special analysis.
Pediatrics 2007: ; 119

13. For physicians and parents alike, the decision to initiate long-term dialysis for a neonate with presumptive ESRD poses a complex ethical quandary.This dilemma derives,at least in part, from the paucity of published reports describing the outcomes of infants who initiate dialysis during the first month of life.
Neonates were as likely to terminate dialysis during the study period as were older children. However, the reason for terminating dialysis differed significantly between the 2 age groups. Neonates were more likely to terminate because of death, and they were less likely to terminate because of transplantation.

14. Death 17/193 Recovery of function 23/193
Neonates with renal dysplasia or obstructive uropathy are at risk for associated congenital anomalies, either true malformations or deformations, because of severe oligohydramnios. In such cases, the presence of significant comorbid conditions may preclude long-term dialysis as a bridge to renal transplantation, thus excluding these neonates from the NAPRTCS database.
