Although there is debate regarding the timing of initiation of renal replacement therapy (RRT) in adults with end-stage renal disease, there is a paucity of reliable epidemiological data on pediatric patients. The present study was performed to investigate current practice in Japan with regard to the timing of initiation of RRT in children based on estimated glomerular filtration rate (eGFR).


A total of 649 pediatric patients < 20 years old with eGFR at the initiation of RRT between 1 January 2006 and 31 December 2013 were included in the study. Baseline eGFR was calculated for each patient using the Schwartz formula.


eGFR at the start of RRT was 12.1 mL/min/1.73 m2 [interquartile range (IQR) 8.4–16.3]. A total of 209 children (32.2%) had high eGFR (eGFR > 15 mL/min/1.73 m2) at the initiation of RRT. Initiation of RRT was more likely in those undergoing preemptive transplantation (PEKT) with high eGFR [odds ratio (OR) 4.16; 95% confidence interval (CI) 1.95–8.90, P < 0.001]. There were 31 deaths of various causes during follow-up, with infections representing the leading causes of death.


The median eGFR at the initiation of RRT in children showed a wide range of variation. Further studies are needed to investigate the impact of the decision regarding when to initiate RRT in individual pediatric patients.
