Post-marketing Clinical Study of Transrectal High-intensity Focused Ultrasound for Localized Prostate Cancer
In this study, the safety and effectiveness data of Sonablate system, a transrectal high-intensity focused ultrasound therapeutic instrument, in the treatment of localized prostate cancer were collected, and the treatment conditions of patients with other methods (such as radical prostatectomy) were compared and analyzed. Observe the differences in treatment effect, survival rate, postoperative PSA, recurrence and complications. To analyze and compare the clinical outcome, postoperative complications and tumor control of HIFU and robot-assisted laparoscopic radical prostatectomy for localized prostate cancer, and to explore the effectiveness and safety of HIFU in the treatment of localized prostate cancer, so as to provide an alternative treatment for localized prostate cancer.
• Men over the age of Forty;
• Localized prostate cancer for which transperineal template prostate biopsy or MRI targeted biopsy combined with systematic biopsy is performed;
• Ti-T2cN0M0 disease stage; Serum psa \< 20 ng/ml; Gleason score ≤7(3+4 or 4+3 or lower); Or the researcher evaluates the medium-low risk prostate cancer within T2 stage without lymph node and distant metastasis; Treatment was performed using Sonablate® transrectal high intensity focused ultrasound (HIFU) or robot-assisted laparoscopic radical prostatectomy (RALP)
