    Abstract:
    AIM: We present our experience with partial nephrectomy using radiofrequency energy in patients with kidney cancer. METHODS: From July 2002 to February 2007, 15 radiofrequency ablation assisted partial nephrectomies were performed. Five patients had one kidney only. The average tumour size was 34 (range 22-55) mm, and the mean age was 56 (range 45-69) years. The renal pedicle was not clamped. A monopolar cool-tip radiofrequency device under intra-operative ultrasound guidance was used. Our procedure involved inserting a radiofrequency probe around the tumour. The average ablation time was 6-12 min. Afterwards the tumour was removed and analyzed histopathologically. RESULTS: The average follow-up period was 15 (range 1-42) months. Eleven procedures were performed without any complications. In 4 cases, delayed urine leakage was observed. Histopathological examination revealed 13 clear cell renal cell carcinomas and 2 oncocytomas. In all cases the coagulated surgical margins were negative. Currently, the surviving patients have a well-preserved renal function, and there was no tumour recurrence. CONCLUSIONS: Radiofrequency ablation assisted partial nephrectomy seems to be an effective method of nephron-sparing surgery. The major advantages of this procedure include easy tumour extraction and no signs of bleeding.
