To assess the incidence of pediatric AKI after HCT treatment,we conducted a systematic literature review. Databases PubMed, Embase, Cochrane Library, and WOS were searched as of June 2022 to identify studies on the incidence and the risk of death in AKI children undergoing HCT. Random effects and generic inverse variance methods were used, and effect estimates were subsequently derived from individual studies. Twelve cohort studies with 2 159 HCT cases were included in this analysis. The combined estimated incidence of AKI and severe AKI (stage AKI III) was 51% (95% confidence interval (CI) 39–64%) and 12% (95%CI 4–24%), respectively. The estimated incidence of AKI based on RIFLE (pRIFLE), AKIN, and KDIGO criteria was 61% (95%CI 40–82% score I 95.1%), 64% (95%CI 49–79% score I 90.4%), and 51% (95%CI 2–100% score 99.0%), respectively. However, we found no significant correlation between the years of publication of the included studies and the incidence of AKI.  Conclusions: AKI affects approximately half of the children after HCT. With the advancements in medical techniques, it is expected that AKI in this population will decrease gradually.What is Known:• Hematopoietic stem cell transplantation is recognized as a treatment for malignant and non-malignant diseases in children.• Hematopoietic stem cell transplantation causes acute kidney injury in children.What is New:• This metanalysis showed that the overall frequency of post-HCT AKI in children is 51%.• The frequency of severe AKI after HCT was found to be 12%.
