[ABSTRACT]ObjectiveTo investigate the status and classification of pediatric renal artery variations using the Hisense CAScomputer-assted surgerysystem.MethodsLoweradominalcontrast-enhanced CTimages werecollctedfromthechildrenwithnon-kidneydiseaseorhealthychildreninTheAfliatedHospitalofQingdao UniversityfromJanuary2Ol3toDecember 2024，and theimages were importedintothe HisenseCAS system to perform thre-dimensionalreconstructionandconstruct the modelofthekidney.Thestatusandclasificationofpediatricrenalarteryvariationsweresummarizedandanalyzed.Results Left renal artery variations accounted for 10.78% ，while right renal artery variations accounted for 10.28% ，with no significant difference between the two sides （ P>0.05 ）. There were four types of renal artery variations，i.e.，prehilar renal artery branch type （typeI），accessoryrenalarterytype（typeII），iaraccessoryarterytype（typeIl），ndmixedtype（typeIV），ccoutingfor 16.79% ， 5.76% ， 3.01% ，and 0.50% ，respectively. Conclusion The model of the kidney constructed based on the Hisense CAS systemcanclearlyshowtheshapeoftherenalarteryandclarifythetypeofrenalarteryvariation，which providesananatomical basis for the preoperative planning of renal surgery and a reference for subsequent research.
