A High-Intensity Focused Ultrasound (HIFU) treatment session for prostate cancer typically lasts anywhere from 1.5 to 3 hours, depending heavily on the size of the prostate gland, the volume of targeted cancerous tissue, and whether a focal ablation or a whole-gland procedure is being performed. The procedure is usually conducted under general or regional spinal anesthesia in an outpatient surgical center or hospital setting. Patients generally spend a few hours in recovery following the completion of the acoustic ablation before being discharged home, often with a temporary catheter that is removed within a few days.
