A modified relief of unilateral ureteral obstruction model

2019 
AbstractObjectives: To improve the mouse model of relief for unilateral ureteral obstruction (RUUO) and explore the pathological process of renal fibrosis after the obstruction was relieved.Methods: C57BL/6 mice in model group were randomly divided into RUUO group, improved RUUO group, and UUO group. After leaving Unilateral Ureteral Obstruction (UUO) for 3 days, the obstruction was released by reimplantation way in RUUO group and in reimplantation + catheter way in improved RUUO group. C57BL/6 mice in observation group were randomly divided into 1d RUUO group, 3d RUUO group, 7d RUUO group, and 14d RUUO group. Three days after UUO, the obstruction was released by reimplantation + catheter in four groups. We detected the renal volume, H&E, Masson staining, and immunohistochemistry of kidney pathology on the seventh day after RUUO in model group and on the 1st, 3rd, 7th, and 14th day after RUUO in observation group.Results: Comparing with mice in RUUO group, mice in improved RUUO group had lower renal volum...
