The aim of this study is to verify whether transperineal needle microwave needle ablation under transrectal prostate sonography is safe and effective for the patients with symptomatic benign prostatic hyperplasia.Three patients having International Prostate Symptom Score (IPSS) above 8 and quality of life (QOL) index above 2 were enrolled in this study. After full explanation of the objective and method of this study, which our Institutional Reviewer Board approved, informed consent was obtained from all patients. The operations were performed under general anesthesia in all cases. The mean operation time was 52 min. Postoperatively, the IPSS and QOL index improved from 14.7 to 10.3 and 6.0 to 4.7, respectively. Furthermore, the maximum urine flow rate increased from 6.3 to 14.3 mL/s, and the volume of prostate decreased from 70.3 to 35.1 cm3 after 3 months. There were no surgical complications. We concluded that transperineal needle microwave needle ablation under transrectal prostate sonography was safe and effective for the patients with symptomatic benign prostatic hyperplasia.
