Laparoscopic radiofrequency renal ablation in patients with simultaneous visceral tumors: long-term follow-up.

Abstract

PURPOSE:

To report our experience with in situ laparoscopic radiofrequency ablation (RFA) of renal tumors.

PATIENTS AND 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).

CONCLUSION:

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.
