为了探讨体外冲击波碎石（ESWL）治疗过度肥胖患者上尿路结石的方法，应用西门子Lithostar碎石机治疗过度肥胖患者上尿路结石30例，结果碎石总成功率为96．7％（29／30），疗效满意。并提出对肥胖者上尿路结石的定位和治疗可采取大后斜位（50～85°）或侧卧位（90°）。认为通过呼吸门控触发、尿道导管插入术、治疗床旁安装可调支架和适当增加冲击电压与冲击次数等辅助手段可进一步提高碎石效果。
To investigate the method of extra-shock wave lithotripsy (ESWL) in the treatment of upper urinary calculi in over-obese patients, 30 patients with upper urinary tract stones were treated with Siemens Lithostar lithotripsy machine. The results showed that the gravel assembly success rate was 96.7% (29 / 30), the effect is satisfactory. And put forward the obstruction of upper urinary tract calculi can be taken after the big oblique position (50 ~ 85 °) or lateral position (90 °). It is believed that the gravel effect can be further enhanced by respiratory gating triggering, urethral catheterization, adjustable bedside installation of adjustable support, and appropriate increase of impulse voltage and impact times.
