Little is known about pediatric nephrology (PN) prenatal consultations for congenital anomalies of the kidney & urinary tract (CAKUT) or possible initiation of kidney replacement therapy (KRT) in neonatal end stage kidney disease (N-ESKD). The aims were to evaluate PN practice patterns for prenatal counseling of fetal CAKUT & to describe criteria used by PN to offer KRT in N-ESKD.


A 35 question Qualtrics® survey was distributed via the North American Pediatric Renal Trials and Collaborative Studies email list between 1/1/2021-3/31/2021.


39 of 108(36%) participating pediatric sites in the US & Canada responded. Median number of faculty (MDs, APPs, APRNS) per center was 7. Median chronic hemodialysis (HD) and peritoneal dialysis (PD) patients per center were 8 & 8,respectively. 38(97%) centers provide prenatal consultation for fetal CAKUT and KRT for N-ESKD. Of those 38 centers,71% report only a select number of non-trainee workforce members (median 2 per center) participate in prenatal consults. 47% of centers have either written/unwritten criteria for offering KRT in N-ESKD.The most common contraindications to KRT was parental refusal(61%;Table 1). The most common birth weight contraindication was <1500g(52%). 82% of centers reported <5 neonates with ESKD were started on KRT within the past year. 58% of centers use HD therapies as a bridge to PD in N-ESKD(Figure 1); 100% of centers report PD as the primary modality at discharge.


Many PN programs provide prenatal consultations for CAKUT diagnoses by a select group of non-trainee workforce members. Only 50% of centers use written/unwritten criteria for decisions about KRT initiation in N-ESKD. Further multi-center research regarding prenatal consultations and neonatal KRT outcomes is necessary to provide greater evidence based practice.
