<prompt> Renal vein thrombosis is most commonly associated withDiabetic nephropathyMembranous glomerulopathyMinimal change diseaseMesangio-proliferative glomerulonephritis  <response>: Renal Vein ThrombosisRVT:The left renal vein is more commonly involved and two-thirds of cases are bilateralEtiology: 1. endothelial damage-Homocystinuria, endovascular intervention, and surgery 2. Venous stasis-Dehydration, retroperitoneal fibrosis and abdominal neoplasmscompression and kinking of the renal veins 3. hypercoagulable states-proteins C and S, antithrombin deficiency, factor V Leiden, disseminated malignancy, oral contraceptives, APLA, nephrotic syndromemembranous nephropathy It can either present with flank pain, tenderness, hematuria, rapid decline in renal function, and proteinuria or it can be silentDiagnostic screening can be performed with Doppler ultrasound; the most sensitive test is CT angiographyTreatment for RVT is anticoagulation and therapy for the underlying cause; Endovascular thrombolysis may be used; Nephrectomy in life-threatening complicationsRef: Harrisons 18e p2382
