Since very little normal kidney tissue is destroyed, this is an attractive option for patients whose kidney function may already be compromised or who are otherwise poor surgical risks. The reported experience of Dr. Gervais and her colleagues covers 18 tumors in 16 patients, not counting one being treated to palliate hematuria rather than for tumor control. In 12 of 13 exfoliative tumors, post-treatment absence of enhancement on computed tomography or magnetic resonance imaging suggests complete tumor ablation.
Treatment is still in progress for the remaining tumor.
Dr. Gervais attributes this differential effect to the heat sink represented by the central veins. Nevertheless, the rate of growth has been demonstrably slowed in one central tumor, with no pre-treatment data available for the other two. Exfoliative tumors that are 3-cm in diameter or smaller have consistently been ablated with one treatment, but larger tumors often require repeat treatments. Hematuria with oliguria or anuria developed in two patients who were treated with ureteral stenting and a Foley catheter, respectively. However, creatine levels did not return to normal in the latter patient.
