Utility of iodinated contrast medium in hydrodissection fluid when performing renal tumor ablation.

In 21 patients undergoing percutaneous renal tumor ablation, hydrodissection with use of a mixture of 5% dextrose in water and iodinated contrast medium was performed to prevent thermal injury to adjacent structures. This technique allows for the movement of adjacent organs as well as improved differentiation among the hydrodissection fluid, renal tumor, and adjacent tissues.
