Aims and objectives
The incidence of the Renal cell carcinoma(RCC) is 4 per 100000 people per year and its 5-year relative survival rates is almost 72 % between 2003 and 2009 in United States [1]. Detection of the RCC is increased by frequent use of the cross-sectional imaging for other reasons,
and most of incidental RCC measured less than 4 cm (T1 stage) [2]. To treat T1 stage RCC,
primarily partial nephrectomy (PN) was performed as standard treatment.
Recently,
considering general condition of the patients,
minimal invasive technique including radiofrequency ablation (RFA) was emerged as alternative treatment options for T1 stage RCC [3]. However,
outcome of the RFA and PN was still controversial [4,5]. To improve the outcome of the RFA,
we used ultrasonography (US)-CT fusion imaging-guided RFA because conventional RFA was performed under one of the CT or US guidance.
And we compared outcome of the fusion imaging-guided RFA with laparoscopic partial nephrectomy (LPN) for the treatment of T1 stage renal cell carcinoma (RCC) to confirm the effectiveness of the RFA.
