This is an interventional treatment trial for Localized Prostate Cancer focused on measuring HIFU, Prostate Cancer, Focal, Quality of life, Index study Read More

Inclusion Criteria:

• OR Gleason score of 6 AND corresponding focal lesion on MRI with a PIRADS (Prostate Imaging Reporting and Data System) score ≥4/5 and a diameter ≥5 mm,
• OR Gleason score of 7 (3+4) whatever the biopsy invasion length or the MRI results may be.
• Patient with normal anal and rectal anatomy.
• Patient with a condition corresponding to an ASA (American Society of Anesthesiologists) classification 1 or 2.
• Patient for which treatment by focal HIFU (without performing an associated TURP) has been validated in Multidisciplinary meeting.
