title: Laparoscopic radiofrequency renal ablation in patients with simultaneous visceral tumors: long-term follow-up.
abstract: OBJECTIVE
  To report our experience with in situ laparoscopic radiofrequency ablation (RFA) of renal tumors.
  
  
  METHODS
  From September 2000 to May 2002, two men, 81 and 71 years old, and one woman, 75 years old, were referred to our department for right renal clear-cell carcinoma <3.5-cm diameter. The 71- year-old patient had only one kidney. Because of the tumor location, the percutaneous route was not considered the approach of choice. Moreover, a simultaneous large right adrenal incidentaloma (myelolipoma) and a right colon cancer were known to be present in the second and third patient, respectively. The aforementioned findings suggested the laparoscopic route as a preferable technique to treat both the renal and the other morbidities.
  
  
  RESULTS
  Under laparoscopic ultrasonography control of tine placement, a 20-minute thermoablation cycle at 100 degrees C mean temperature was performed. Including right colectomy and right adrenalectomy, the operative time was 120, 200, and 275 minutes, with postoperative hospital stays of 3, 4, and 6 days for the three patients, respectively. Abdominal CT scans after 1 and 4 weeks and then every 6 months confirmed complete treatment of the lesion at 44 months' average follow-up (range 36-56 months).
  
  
  CONCLUSIONS
  When percutaneous access is not feasible or the patient should undergo another laparoscopic procedure simultaneously, laparoscopic RFA of renal tumors is feasible and effective, as shown by long-term follow-up.
