Abstract
Purpose: We wanted to report the our early experience with performing nephron-sparing radiofrequency ablation(RFA) of renal tumor.
Materials and Methods: Three percutaneous RFAs were performed under combined computed tomography(CT) and ultrasonogram guided, and two intraoperative ultrasonograpy-guided laparoscopic RFAs were performed since June 2004. The treatment indications were localized, small (＜4cm), solid renal masses in elderly patients and also the same type masses in the patients with comorbid conditions. The follow-up studies included physical examination, CBC, serum creatinine, urine analysis and kidney CT, and these were performed at day 1, 1 week, 1 month, 3 months, 6 months and 1 year after ablation, and then semi-annually thereafter. The mean follow-up duration was 8.8 months(range: 5-12 months).
Results: All five patients underwent successful RFA without any serious events. One patient had a mild perinephric hematoma and another patients had mild gross hematuria postoperatively. With a mean follow-up of 8.8 months, none of the patients showed any residual tumor on follow-up contrast-enhanced CT after the final tumor ablation. Complete tumor ablation was achieved after a single treatment session in 80% of the patients and in 20% of patients after the subsequent ablation sessions.
Conclusion: Percutaneous or laparoscopic RFA is a promising nephron- sparing treatment for selected patients with small renal mass. Contrast- enhanced CT performed immediately after ablation is a reliable method to exclude residual viable tumor. The ultimate role for this modality will continue to evolve and this warrants further studies. (Korean J Urol 2006; 47:244-251)
