Renal Ablation Technologies – Impact on the Treatment of Small Renal Masses

Posted by Thomas W. Jarrett, MD | Oct 2024

Thomas W. Jarrett, MD, explores the evolving role of renal ablation technologies in managing small renal masses (SRMs), highlighting their increasing importance as an alternative to traditional surgical approaches. In this 20-minute talk, he provides a detailed overview of the various ablation techniques, including radiofrequency ablation (RFA), cryoablation, and microwave ablation, emphasizing their distinct mechanisms of action and clinical applications.

The presentation delves into the outcomes associated with renal ablation, discussing the advantages and disadvantages of the different ablation options. Dr. Jarrett also addresses the limitations and challenges of renal ablation, including the potential for incomplete tumor destruction and the difficulties in monitoring long-term outcomes.

Life Expectancy as It Relates to the Treatment of Urologic Cancers

Posted by Thomas W. Jarrett, MD | Jul 2024

Thomas W. Jarrett, MD, discusses the impact of life expectancy on urologic cancer treatment and management in the United States. He begins by highlighting outdated life expectancy models and the importance of assessing life expectancy prior to exploring treatment options.

Dr. Jarrett then discusses the traditional methods of assessing life expectancy and their failure to account for patient comorbidities. He lists the most significant comorbidities which impact life expectancy according to their hazard score.

Dr. Jarrett then addresses overall trends in life expectancy in the United States. He notes that life expectancy sharply decreased during COVID-19 and that the United States has yet to recover compared to European life expectancy trends.

Dr. Jarrett concludes by illustrating the influence of perceived life expectancy on urologic cancer management and outcomes. He discusses the impact of life expectancy on treatment options for urothelial cancer, testicular cancer, renal cancer, and prostate cancer.
