Many reports of clinical outcomes following treatment of localized prostate cancer suffer from lack of prospective long-term data using objective and validated outcome instruments. The purpose of this research database is to prospectively collect data to assess treatment related complications, oncologic outcomes and urinary/sexual function, and identify predictors of complications, oncological control and functional outcomes after Hhigh-intensity focused ultrasound (HIFU) ablation of prostate cancer with the intent to guide further research and improve patient care. We will include subjects who will have a HIFU procedure performed from all Sub-Investigators included in the study.
