ABSTRACT：ObjectiveTo investigate the diagnosisand treatment of 2cases with spontaneous renal vascularrupture，and discussthe posiblecausesand treatment methods of thisdisease.MethodsTheclinicaldataand treatment methods of the 2 patients with spontaneousrenal vascularrupture treatedwithrenalarteryembolizationin Universal Global Xi'an Beihan Hospital were analyzed.Relevant literature was reviewed to summarize the posible causes of this condition.ResultsThe patientshad noobvious historyoftraumaandnoobviousabnormalcoagulationfunction，and soughttreatmentdueto sudden lumbarandabdominal pain.Laboratory tests revealed significantly decreased hemoglobin level，and elevatedblood glucose （27.8，27.6mmol/L） .Abdominal computed tomography（CT） indicated perirenal hematoma and active bleeding. The bleeding arteries were located attheterminal branchesof theanteriorrenalartery.Preciseembolization was performed using CTangiographyand selective renal arteryangiography plus embolization，achieving an immediate hemostasis sucess rate of 100% .Postoperative hemoglobin level stabilized，andfollow-up CTscansshowed significant absorptionoftheperirenal hematoma without significant deteriorationofrenalfunction.Basedonliteraturereviewandcaseanalysis，thepossblecauseof spontaneous renal vascular rupture in these two patients wasrenal vascularsclerosis due to long-term diabetes.Other common etiologiesof thiscondition included renal tumor，vascular malformation，and hypertension.ConclusionSpontaneous renal vascularruptureisrare.Renalarteryembolization，asaminimally invasive treatment，caneffectivelycontrolbleeding and protectrenal function.Thespecificpathogenesisofthisconditionstillrequires furtherinvestigation.Long-termdiabetes melitus with poor blood glucose control may be associated factors，but more evidence is needed.
