INTRODUCTION: Once reserved solely for non-surgical cases, percutaneous ablation is becoming an increasingly popular treatment option for a wider array of @entity1 with small renal masses and the radiation risk needs to be better defined as this transition continues. MATERIALS AND METHODS: Retrospective review of our @entity703 ablation database revealed 425 @entity1 who underwent percutaneous ablation for treatment of 455 @entity703 over a 5-year time period. Imparted radiation dose information was reviewed for each procedure and converted to effective @entity1 dose and skin dose using established techniques. Statistical analysis was performed with each ablative technique. RESULTS: For the 331 cryoablation procedures, the mean DLP was 6987  mGycm (SD  =  2861) resulting in a mean effective dose of 104.7  @entity2073 (SD  =  43.5) and the mean CTDIvol was 558  mGy (SD  =  439) resulting in a mean skin dose of 563.2  mGy (SD  =  344.1). For the 124 RFA procedures, the mean DLP was 3485  mGycm (SD  =  1630) resulting in a mean effective dose of 50.3  @entity2073 (SD  =  24.0) and the mean CTDIvol was 232  mGy (SD  =  149) resulting in a mean skin dose of 233.2  mGy (SD  =  117.4). The difference in @entity1 radiation exposure between the two renal ablation techniques was statistically significant (p  <  0.001). CONCLUSION: Both cryoablation and RFA imparted an average skin dose that was well below the 2  Gy deterministic threshold for appreciable sequela. @entity703 cryoablation resulted in a mean skin and effective radiation dose more than twice that for RFA. The radiation exposure for both @entity703 ablation techniques was at the high end of the medical imaging radiation dose spectrum.
