The median interval between PN and RFA was 42.7 months (interquartile range [IQR]: 15.4\u201373.3). The median tumor size was 2.1 cm (IQR: 1.6\u20132.4). The median RENAL nephrometry score for recurrent tumors was 6 (IQR: 5\u20137). The median procedure time was 19.0 minutes (IQR: 16.0\u201322.6), with a median postoperative hospital stay of 1 day (IQR: 1-1). With a median follow-up of 29.3 months (IQR: 15.5\u201364.5), the incidences of severe complications, tumor recurrence, and incomplete ablation were 2.2%, 17.4%, and 10.9%, respectively.
