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.
