AB  - PURPOSE: To assess the ability of the Percutaneous Renal Ablation Complexity 
      (P-RAC) scoring system to predict procedural complexity or adverse events (AEs) 
      in adult patients undergoing percutaneous thermal ablation of renal tumors. 
      MATERIALS AND METHODS: A retrospective review of 240 consecutive adult patients 
      who underwent percutaneous thermal renal ablation from 2004 to 2018 was 
      conducted. The P-RAC score was calculated for each renal tumor and procedural 
      complexity recorded. A correlation coefficient was calculated for the P-RAC score 
      and both the number of probes used and procedural duration. Receiver operating 
      characteristic curves assessed the score's ability to predict the use of 
      adjunctive techniques and/or major AEs, classified according to the Society of 
      Interventional Radiology guidelines. RESULTS: For the entire cohort, there was a 
      weak correlation between P-RAC scores and both the number of probes used (r = 
      0.31; P < .001) and procedural duration (r = 0.18; P = .03). When evaluating only 
      patients treated with microwave ablation (MWA), no correlation between P-RAC 
      scores and either the number of probes (P = .7) used or procedural duration (P = 
      .4) was found. The area under the curve (AUC) for the P-RAC score to predict the 
      use of adjunctive techniques was 0.55 and 0.53 for the entire cohort and MWA 
      group, respectively. The AUC for the P-RAC score to predict major AEs was 0.70, 
      0.71, and 0.73 for the entire cohort, MWA group, and cryoablation group, 
      respectively. CONCLUSIONS: The P-RAC scoring system is limited in its ability to 
      predict percutaneous thermal renal tumor ablation procedural complexity, 
      especially in patients treated with MWA. The scoring system may have a role in 
      identifying patients at risk of major AEs.
