低脉冲ESWL治疗尿路结石分析

Study on low pulse ESWL in treatment of urinary tract calculi

目的观察低脉冲组体外冲击波碎石术(ESWL)对尿路结石的治疗效果。方法回顾总结我院2004～2008年1086例患者的ESWL治疗。随机等分两组;治疗组(低脉冲)和对照组(高脉冲)。结果两组碎石冲击次数的比较低脉冲组比高脉冲组最高冲击次数减少3290次左右,最低冲击次数减少2044次,平均冲击次数减少2667次。患者的上机治疗时间由45～85min减少到5～20min。低脉冲组的平均冲击次数和平均碎石时间与高脉冲组比较差异有统计学意义(P<0.05)。结论低脉冲组ESWL治疗尿结石时间短、损伤小、疗效确切,是一种安全、有效的方法 ,值得推广。

Objective To explore the application of low pulse ESWL in treatment of urinary tract calculi.Methods The clinical data of 1086 cases（792 male cases and 294 female cases）with an average of 31.7 years old admitted in this hospital during 2004 to 2008 were retrospectively summarized and analyzed,they were randomly divided into trial group（with low pulse）and control group（with high pulse）.Results There was relatively low impact on number of pulse,the number of pulse in trial（low pulse）group was reduced as many as approximately 3290 times at maximum and approximately as 2044 times at the minimum and the average reduction in pulse number was 2667 times.Therapeutic time of patients was reduced from 45 ～ 85 min to 5 ～ 20 min.There was significant difference in average impact of low-frequency and average time between these two groups（P〈0.05）.Conclusion The average times and therapeutic course for low-pulse ESWL in treatment of urinary tract calculi are shorter,its damage is small and curative effect is exact.It is a safe and effective method in treatment of urinary tract calculi and it is worthy to be recommended.
