高强度聚焦超声刀(HIFU)作为治疗局灶性肾肿瘤的新方法近几年在国内外得到迅速发展。研究发现体外HIFU同手术切除相比无法造成足够的瘤体破坏;腔镜下HIFU可有效避免肾脏移动和声分裂对疗效的影响,肿瘤清除率高。HIFU治疗肾肿瘤仍处于试验阶段,其疗效评估还需要大量的长期随访及前瞻性临床试验。 High intensity focused ultrasound knife (HIFU) as a new method of treatment of focal renal tumors in recent years at home and abroad have been rapid development. The study found that in vitro HIFU compared with surgical resection can not cause enough tumor destruction; endoscopic HIFU can effectively avoid the impact of renal movement and acoustic splitting on the efficacy of tumor clearance rate. HIFU treatment of renal tumors is still in the experimental stage, and its efficacy evaluation also requires a large number of long-term follow-up and prospective clinical trials.
