Renal function injury represents a final common outcome of congenital obstructive nephropathy and has attracted a great deal of attention. However the molecular mechanisms are still not fully established. In this study, we compared transcriptome sequencing data of miRNAs of renal tissues from congenital hydronephrosis children with or without renal functional injury, in order to better understand whether microRNAs could play important roles in renal functional injury after ureteropelvic junction obstruction. A total of 22 microRNAs with significant changes in their expression were identified. Five microRNAs were up-regulated and 17 microRNAs were down-regulated in the renal tissues of the hydronephrosis patients with renal function injury compared with those without renal function injury. MicroRNA target genes were predicted by three major online miRNA target prediction algorithms, and all these mRNAs were used to perform the gene ontology analysis and Kyoto Encyclopedia of Gene and Genomes pathway analysis. Then, twelve candidate human and rat homologous miRNAs were selected for validation using RT-qPCR\n                    <jats:italic>in vitro<\/jats:italic>\n                    and\n                    <jats:italic>in vivo<\/jats:italic>\n                    ; only miR-187-3p had a trend identical to that detected by the sequencing results among the human tissues,\n                    <jats:italic>in vivo<\/jats:italic>\n                    and\n                    <jats:italic>in vitro<\/jats:italic>\n                    experimental models. In addition, we found that the change of miR-187-3p\n                    <jats:italic>in vivo<\/jats:italic>\n                    was consistent with results\n                    <jats:italic>in vitro<\/jats:italic>\n                    models and showed a decrease trend in time dependence. These results provided a detailed catalog of candidate miRNAs to investigate their regulatory role in renal injury of congenital hydronephrosis, indicating that they may serve as candidate biomarkers
