    Abstract:
    OBJECTIVE: To compare morbidity, oncological and functional outcomes of percutaneous radiofrequency ablation (RFA) and partial nephrectomy in indications of renal tumor treatment with imperative nephron-sparing procedure. PATIENTS AND METHODS: Between January 2005 and December 2010, 50 consecutive patients were referred in our center for NP or RFA for a renal tumor with either a renal function impairment defined as estimated glomerular filtration (eGFR) less than 60 mL/min/1.73 m(2), and/or solitary kidney and/or bilateral tumors. Perioperative outcomes were compared. RESULTS: Thirty-six PN and 14 RFA were performed. RFA patients were older (79.2 vs. 62.5 years old), had a higher ASA score (3 vs. 2), a lower RENAL score (6 vs. 7.5) and a lower rate of tumor on solitary kidney or bilateral tumors (P=0.009). Overall complications (29.4% vs. 6.3%), transfusions (20.6% vs. 0) and longer hospital stay (9 vs. 3 days) were more likely to occur in the NP group. During a median follow-up of 22 months (4.3-53.7), eGFR decrease was similar between the two groups (P=0.34). On multivariate analysis, PN was associated with an increased occurrence of overall complications (OR=14.09, P=0.02) but with a similar eGFR decrease. No patient died. CONCLUSION: For patients with an indication of treatment of renal tumor and imperative nephron-sparing procedure, RFA seems to provide low morbidity and comparable functional outcomes as partial nephrectomy. Our limited follow-up does not permit to conclude on oncologic data.
