[Prolonged survival after right nephrectomy, excision of the inferior vena cava and ligation of the left renal vein: a case report].

A 70-year-old male patient was found to have a right renal mass with tumor thrombus extending into the inferior vena cava. Right nephrectomy, excision of the vena cava and ligation of the left renal vein were performed. Postoperatively, there was neither episode of hypotension nor edema in the lower extremities, but the patient experienced transient renal failure. The serum creatinine level elevated to 12. 5 mg/dl on the 6th postoperative day, but decreased to 2. 8 mg/dl on the 48th postoperative day. It was 1. 4 mg/dl 3 years after surgery without any specific treatment. He was clinically free of disease and in good health 3 years after surgery.
