Focal laser ablation (sometimes described as MRI-guided laser interstitial thermal therapy or similar trade names) delivers laser energy into a planned region of the prostate while MRI provides real-time temperature feedback.
Laser fibre is placed perineally into the lesion or zone to be treated. MRI thermometry helps the operator stay within predefined temperature and volume limits relative to adjacent structures such as the urethra and neurovascular bundles.
Published cohorts usually restrict treatment to MRI-visible, biopsy-proven disease in men who accept close follow-up. The presence of high-volume or bilateral disease outside the target zone may argue for whole-gland strategies instead.
Oncological and functional outcomes vary by series, technique generation and length of follow-up. Ask your team how they define treatment success, when repeat biopsy or imaging is planned, and what retreatment options remain.
You can ask for a second opinion on imaging, diagnosis and treatment options before you decide.
