High-Intensity Focused Ultrasound for Focal Ablation of Prostate Tissue: An Observational Study of Multiparametric MRI and Ultrasound Fusion Imaging for Guidance
University of California, Los Angeles
Summary
The Sonablate HIFU device was approved by the U.S.FDA for prostate tissue ablation in October, 2015. The purpose of this observational research study is to investigate the localized treatment of prostate cancer using HIFU through clinical data and health-related quality of life (HRQOL) questionnaires.
Description
This observational study will serve to collect data from medical record review and questionnaires before and after High Intensity Focused Ultrasound (HIFU) for focal ablation of prostate tissue. The subject will have already undergone or opted to receive the HIFU procedure as part of standard of care in order to participate in this study.

Interventions
- DeviceSonablate HIFU device
In this study, we will be using the Sonablate 450 HIFU System. The Sonablate HIFU device was approved by the U.S. FDA for prostate tissue ablation in October, 2015. HIFU is an example of focal therapy, where the intervention involves targeting diseased areas of prostate tissue, while preserving healthy prostate tissue and minimizing damage to surrounding structures.
