体外冲击波碎石疗效的影响因素及对策

体外冲击波碎石技术是目前各种泌尿系结石治疗方法中的首选，但在体外冲击波碎石过程中经常会出现影响治疗效果的各种因素：由于元器件质量问题、安装问题、老化问题等，造成性能参数发生变化，影响冲击波能量的发生、传导、聚集；人体本身的肥胖、胃肠积气、腹式呼吸、结石的理化性质等因素，使能量传递不良、聚集不良、效率变差。文中列举和分析了各种影响疗效的因素和原因，并提出了相应的解决方案。

Influence Factor and Strategy on ExtracOrporeal Shockwave Lithotripsy

Extracorporeal shockwave lithotripsy （ESWL） is the preferred tool in the urologist＇s armamentarium for the treatment of renal stones at present. But the influence factors in using ESWL treatment process were appeared. The quality components, installation and aging problem can change performance parameters and affect on shockwave energy, transmission and aggregation. The badness of energy transfer and assembly can be influenced by overweight body, flatulence, abdominal and calculus physicochemical property. The varieties of influence factor and causes are analyzed and enumerated. The corresponding solution project can be assigned at the same time.
