Transurethral microwave thermotherapy is designed to destroy non-malignant tissue by exposure to a cytotoxic temperature ranging from 45 degrees C to more than 70 degrees C. The combination of microwave-induced heat administered transurethrally and protection of the urethra by a cooling circuit allows delivery of sufficient power to induce coagulation of the periurethral prostatic tissues without any form of anaesthesia part from instillation of anaesthetic jelly into the urethra. Treatment takes only 30 minutes. Strict security limits (urethral temperature and rectal temperature) ensure a low complication rate. The therapeutic efficacy of thermotherapy is situated between that of drugs and endoscopic surgery. The effect is lasting. The development of a tailor-made treatment for each patient should increase the response rate of this technique.
经尿道微波热疗旨在通过暴露于45摄氏度至70多摄氏度的细胞毒性温度来破坏非恶性组织。经尿道给予微波诱导的热量与通过冷却回路保护尿道相结合，无需除了向尿道内注入麻醉凝胶之外的任何形式麻醉，就能输送足够的能量以诱导尿道周围前列腺组织发生凝固。治疗仅需30分钟。严格的安全限制（尿道温度和直肠温度）确保了低并发症发生率。热疗的治疗效果介于药物和内镜手术之间。效果持久。为每位患者量身定制治疗方案应能提高该技术的有效率。
