3:45 PM Abstract No. 341 Pivotal study of magnetic resonance imaging–guided transurethral ultrasound ablation in men with localized prostate cancer: 12-month clinical and imaging outcomes

MRI-guided transurethral ultrasound ablation (TULSA) is an incision-free in-bore procedure for customized prostate ablation using directional thermal ultrasound under real-time MRI thermometry guidance and control. We report 12-month outcomes from the TULSA-PRO Ablation Clinical Trial (TACT) pivotal study. TACT enrolled 115 men with localized prostate cancer at 13 sites. Treatment intent was whole-gland ablation sparing the urethra and urinary...
