RTx is currently the best treatment for children with ESRD. This study retrospectively analyzed the outcomes of growth after RTx using the pediatric-to-pediatric allocation strategy and some factors that may affect it. From March 2012 to August 2016, 8 en bloc and 38 single pediatric RTxs were performed at our center using organs from small pediatric deceased donors (weight < 15 kg). Growth before and after RTx was analyzed according to the height-for-age z-score at RTx, the 3-year follow-up, and adulthood and compared between the procedures. The chi-square test and multiple linear regression analysis were used for statistical analyses. Overall, 79.2% of children were diagnosed with chronic nephritis before RTx; 14.6% of cases were due to congenital urinary tract malformation, and 6.3% of cases were due to unknown causes. All grafts and patients survived postoperatively. The mean estimated GFRs were 92.7 ± 28.6 mL/min/1.73 m2 , 100.9 ± 32.3 mL/min/1.73 m2 , and 110.1 ± 34.8 mL/min/1.73 m2 at 1, 2, and 3 years' postoperatively, respectively. The children's postoperative growth and development, particularly during the first year postoperatively, improved but were negatively correlated with age and the height-for-age z-score before RTx. The growth of children after RTx was moderate and accelerated during prepubescence. The rate of post-RTx growth during the first year postoperatively was unrelated to the recipient's sex or duration of dialysis (P > 0.05) but was negatively correlated with age at RTx (r = -0.349, P = 0.043). Future studies on the long-term outcomes are still needed.
