TULSA (Transurethral Ultrasound Ablation) is an advanced, incisionless medical procedure used to treat prostate diseases, including localized prostate cancer and benign prostatic hyperplasia. Guided continuously by real-time magnetic resonance imaging (MRI) and closed-loop thermal feedback, a specialized transurethral device delivers directional ultrasound energy to destroy diseased prostate tissue precisely while protecting surrounding critical nerves and urinary structures.
