title: Ablative techniques for the management of kidney cancer.
abstract: For lesions smaller than 4 cm, nephron-sparing surgery has been shown to be oncologically equivalent to radical nephrectomy, albeit with the advantage of preservation of overall renal function. As such, partial nephrectomy became the first-line treatment option for localized, small renal masses. Minimally invasive options associated with limited morbidity--such as probe-ablative procedures--are, however, being investigated in selected patients for whom invasive, nephron-sparing surgery (whether laparoscopic or open) is undesirable. The main probe-ablative techniques being investigated as alternatives to partial nephrectomy are cryoablation, radiofrequency ablation, and high-intensity focused ultrasound. Advances in imaging, ablative system technologies, and early evidence that in situ tumor ablation can yield comparable results to those achieved with tumor resection in selected cases, have sparked significant interest in these minimally invasive techniques.
