    • ...A percutaneous technique is desirable, particularly in patients for whom surgical procedures pose a high risk [7]...
    • ...A relatively new percutaneous approach is microwave ablation (MWA), which allows cellular destruction of localized tumors while preserving the uninvolved renal parenchyma [7, 10]...
    • ...The aim of this report is to evaluate the feasibility, safety, and preliminary clinical outcome of MWA for small RCCs [7, 10, 12]...
    • ...The main problems with RFA have been the high local recurrence rates in the treatment of masses larger than 3.0 cm in diameter and the incomplete tumor ablation near blood vessels because of the heat sink effect of local blood flow [7, 24]...

    • ...At this time only a few experiences with treatment of RCC have been reported, including a small number of patients [7, 10, 12]...
    • ...Heating of the tissue is based on agitation of water molecules inducing cellular death via coagulation necrosis; the electrical charge on the water molecule flips back and forth 2 to 5 billion times a second, depending on the frequency of the microwave energy [7]...
    • ...With RFA, the zone of active tissue heating is limited to a few millimeters surrounding the active electrode, with the remainder of the ablation zone being heated via thermal conduction [7]...
    • ...Other phase I clinical trials [7, 26, 27] have been performed to confirm the effectiveness of MWA in patients undergoing tumor resection (ablate and resect intraoperative trials)...

    • ...Electromagnetic energy heats tissue by targeting the water molecules and, like RF, induces cell death by coagulative necrosis [75, 76]...
    • ...In comparison, active RF heating is limited to a few millimetres around the applicator, with reliance on conduction of cytotoxic temperatures through the tissues in order to create an ablation zone [76, 97, 98]...
