Objective: We report on a new technique for percutaneous radiofrequency ablation of tumors in the upper pole of kidneys in the presence of intervening lung parenchyma.
Conclusion: Percutaneous radiofrequency ablation of tumors in the upper pole of kidneys with intervening lung parenchyma can be accomplished successfully using a transthoracic approach through an iatrogenic pneumothorax. This technique allows for precise placement and repositioning of the radiofrequency electrode under CT guidance without repeated puncture of the visceral pleura.
