摘要：

目的：探讨光耦合控制技术（OCC）在体外冲击波治疗上尿路结石的临床效果。方法：将407例行体外冲击波碎石（SWL）的上尿路结石患者作为研究对象，随机分为研究组（205例，采用OCC）和对照组（202例，采用盲法耦合技术）。应用多尼尔Compact DeltaⅡUIMS冲击波治疗仪进行碎石，比较两组结石排出率、碎石所需能量、冲击波次数及冶疗时间等，并进行统计分析。结果：研究组和对照组结石排出率分别为80.5%和63.9%（P<0.01），碎石所需的能量分别为（1.7±0.6）和（2.4±0.6）级，冲击波次数分别为（1900±403）和（2400±440）次，治疗时间分别为（21.5±5.3）和（27.6±7.3）min，两组比较差异均有统计学意义（P<0.01）。结论：应用OCC进行碎石能够更好地传递冲击波，减少能量的损耗，提高碎石效果。

Objective:To study of the efficacy of optical coupling control technique in shock wave lithotripsy(SWL).Methods:Four hundred and seven patients with urinary stones who underwent SWL were enrolled in this study,and the lithotripter,electromagnetic Dornier Compact DeltaⅡUIMS was used.All patients were randomized into two groups:the study group(OCC,n=205) and the control group("blind" coupling,n=205).The statistical analyses were performed by using a software package SPSS 22.0 to compare the SWL results between the two group.Results:The overall stone-free rates after 3 months in study and control groups were 80.5% and 63.9%,respectively(P<0.01).There were statistical differences in the results about energy level(1.7±0.6,2.4±0.6),numbers of shock wave(1 900±403,2 400±440) and treatment time[(21.5±5.3),(27.6±7.3)min]between the two groups(P<0.01).Conclusions:The lithotripter with OCC have excellent shock wave transmission properties with the least possible loss of energy,and it could improve the efficacy of SWL.
