Single 15-Min Protocol Yields the Same Cryoablation Size and Margin as the Conventional 10-8-10-Min Protocol: Results of Kidney and Liver Swine Experiment.

Fifteen-minute cryoablation yielded an ablation size and margin identical to that of the conventional 10-8-10-min protocol. Within the ablated region, cell death was uniform. The only difference was a larger cryoablation zone in hepatic tissue compared to renal tissue, likely attributable to differences in blood perfusion.
