The objective of this study is to present outcomes of MRI-guided laser ablation for early stage renal cell carcinomas and to describe associated prognostic factors in a consecutive cohort of patients with relative long-term longitudinal follow-up. A prospective cohort of patients presenting with pathology-confirmed RCC underwent MRI-guided biopsy and subsequent laser ablation. Twenty-four consecutive patients presenting with 35 RCC were recruited. Follow-up MRI imaging was obtained in all cases with a median follow-up period of 20 months. Of the different analyzed prognostic factors, R.E.N.A.L nephrometry score was the only one predicting the incidence of complications.
