abstract: OBJECTIVE
  To present one cases of the use of balloon catheter in surgical treatment of renal angiomyolipoma involving the renal vein and vena cava as a tumor thrombus and review literatures.
  
  
  METHODS
  Abdominal ultrasound and CT and MRI demonstrated a large right renal mass with tumor thrombus in the inferior vena cava. Right nephrectomy and en-bloc removal of the intra caval tumor thrombus were performed. A balloon catheter was used to block vena cava under the level of liver vena during the operation.
  
  
  RESULTS
  The pathological diagnosis was angiomyolipoma. The length of the tumor thrombus was 6.5 cm. The patient recovered well 1 year after surgery.
  
  
  CONCLUSIONS
  Renal angiomyolipoma with a tumor thrombus should be paid more attention.
