This investigation describes the technical aspects of using laser fibers to deliver ablative energy to renal tumors during interactive MRI guidance and reports patient tolerance, complication rates, long term efficacy of laser ablation of renal malignancies. The technique represents a considerable departure from the complex handling of cryo- and RFA probes within the MRI environment and is likely to facilitate future dissemination of MRI-guided renal ablation. The procedure is well tolerated with a high safety profile. Long-term follow up results for up to >32 months point to an efficacious ablative technique with no residual or recurrent neoplasms in our series.
