While in town for the #WCET25 @Endo_Society meeting, @DerekLomas and I had to stop by @MayoUrology Arizona and observe @dfrendl perform two IRE cases. A true tri-site collaboration. Thankful for this opportunity.

Compelling arguments by @LondonProstate1 at the Focal Therapy crossfire debate at #AUA2025 -Treatment side effects are reduced 5-10 fold -Iso-effective to radical therapy at 5-10 year -Focal therapy should be offered as a standard option for (eligible) intermediate patients

Great talk on #AI in the OR by @abhinav__khanna at @MNUrological 🤔 Can it estimate bladder tumor size? 🔢 Assist with tasks like counting instruments? 👩🏻‍⚕️Assess surgical skills, incorporate into education 😱 Will robots replace surgeons??! Tip of the iceberg!

@MayoUrology with two posters at #FOCAL2024 POSTER 1) Those are active surveillance with PIRADS 5 lesions disease have lower rates of high-grade disease on targeted biopsy, compared to those with no previous prostate cancer diagnosis. @dfrendl

POSTER 2) Among men undergoing MR fusion prostate biopsy for unilateral PIRADS 3 or 4 lesions, transperineal biopsy resulted in greater disease detection for both targeted fusion and systematic samples. TP biopsy may provide a more thorough pre-treatment assessment for FT.

Had a great time at the @MNUrological fall meeting in Duluth. It was great to connect with colleagues from across the state, including several @MayoUrology alums. After my talk, it was great to take in the views as we cruised on Lake Superior and through Duluth Harbor.
Today’s @MNUrological meeting had it all! ⚡️ Great talk about focal therapy for prostate cancer from @DerekLomas 👨‍⚕️ Catching up with @drvandersteen 🍁 Fall colors (and a boat ride!) in Duluth Harbor
