OBJECTIVE: To study the feasibility and the innocuity of the treatment by radiofrequency of @entity703 . MATERIAL AND METHODS: From June 2000 to September 2001, 10 @entity703 in 6 @entity1 were treated by radiofrequency. The mean age of the @entity1 was 57 years. The mean @entity5 diameter was 20 mm. Indications for partial surgery were 3 solitary kidneys, one @entity1 with @entity177 , one @entity1 with @entity280 and one @entity1 in whom several @entity359 were @entity8 . 4 @entity1 were treated via a lumbar incision and 2 were treated percutaneously (one with ultrasound guidance and the other with computed tomography guidance). @entity1 were reviewed by imaging (CT and/or MRI) with injection of contrast agent to demonstrate complete devascularization of the @entity5 . RESULTS: Treatment lasted an average of 180 minutes. The intraoperative complication rate was 16%. The mean hospital stay was 9 days (4 days for the percutaneous route). Nine @entity5 (5 @entity1 ) were devascularized after a single session. One @entity1 (treated via the percutaneous route under ultrasound guidance) showed persistence of @entity5 tissue (identified by CT). A second session, performed 4 months later, allowed complete devascularization of the @entity5 . The mean follow-up is 13 months. CONCLUSION: This study demonstrates the feasibility and safety in terms of renal function of radiofrequency treatment of @entity703 . However further studies are necessary to precisely define the radiological criteria of @entity5 @entity39 and to evaluate the long-term results of this method (outcome of @entity5 tissue, metastatic risk, @entity5 recurrence along the needle track in the case of a percutaneous approach). This treatment must be reserved for selected @entity1 .
