Bipolar radiofrequency ablation using wet-cooled electrodes: an in vitro experimental study in bovine liver.
OBJECTIVE
Our aim was to evaluate the performance of hypertonic saline (HS)-enhanced bipolar radiofrequency ablation using wet-cooled electrodes versus monopolar radiofrequency ablation to create coagulation necrosis in explanted bovine liver.


CONCLUSIONS
HS-enhanced bipolar radiofrequency ablation using the wet-cooled electrodes shows better performance in creating coagulation necrosis than the monopolar mode.
