This webinar will explore a retrospective analysis was performed of 107 patients treated with CT-guided renal ablation for clinical stage T1 renal cell carcinoma between February 2005 and December 2017. Patients were stratified into two cohorts on body mass index of ≥ 40 kg/m2 (morbidly obese) and body mass index of 18.5 to 24.9 kg/m2 normal-weight). Anesthetic and radiation dosages, procedure time, residual disease, and local recurrence and adverse events were analyzed between the two groups. Kaplan-Meier statistics evaluated cancer-related outcomes for each group.

Learning Outcomes

After attending this session, participants will be able to:

  • Describe how CT guided renal ablation is a safe and effective procedure in patients with morbid obesity.
  • Describe how morbidly obese patients appear to be at higher risk for hematoma and require longer procedure time, higher anesthetic dose and radiation exposure.
