Abstract:
Objective To evaluate the clinical feasibility of laparoscopic cool-tip radiofrequency ablation (LCRFA)for renal cell carcinoma. Methods Twelve selected cases of primary renal, ceil carcinoma underwent LCRFA. Of them, 4 cases of left renal carcinomas, 7 cases had right renal carci-nomas and 1 case had bilateral renal carcinomas. The maximum diameter of the tumors was 2.1-8. 5 era. Eleven cases were T, No M0 and the other one was T2 N0 M0. Results The mean operation time was 92±24 min, and the mean blood loss was 50±29 ml. None of the cases need blood transfusion post-operation. No laparoscopic operative complications were observed. Six weeks after operation, complete ablation was achieved in 12 lesions and partial ablation in 1, with a complete ablation rate of 92.3%(12/13). There was no statistic change of Hb. ESR. SCr and GFR after operations (P>0.05). Ten cases underwent CT examination 3 months after the treatment ,9 cases showed complete necrosis of tumor,1 case showed partial necrosis. No recurrence was found. All of the 12 cases remained sur-vived during the follow-up for 1-16 months(median,7.8 months). Conelusions LCRFA for renal cell carcinoma is an accurate and effective intervention with a low incidence of complications, and is more accurate than ultrasound-guided pereutaneous radiofrequency ablation.
