Protecting the Ureter during Radiofrequency Ablation of Renal Cell Cancer: A Pilot Study of Retrograde Pyeloperfusion with Cooled Dextrose 5% in Water

RF ablation of RCC within 1.5 cm of the ureter is feasible with cooled D5W retrograde pyeloperfusion and is not associated with reduced efficacy, ureteral injury, or early recurrence.
