title: Renoduodenal fistula after renal tumor ablation with radiofrequency.
abstract: OBJECTIVE
  To report a renoduodenal fistula after renal tumor ablation with radiofrequency (RFA).
  
  
  METHODS
  A 1-inch right anterior renal cell carcinoma was subjected to percutaneous RFA under sedation. We used a 14-gauge probe guided by ultrasonographic images in real time.
  
  
  RESULTS
  On the fifth day the computerized tomography with double contrasts showed a fistula between the pelvis and the duodenum.
  
  
  CONCLUSIONS
  A major concern regarding this approach relates to the anterior renal tumor and the guided images during the procedure. To our knowledge, there has never been any report of renoduodenal fistula after RFA.
