目的:对肾结石ESWL疗效判断影响因素进行研究和探讨。方法:以对我院2006年9月至2012年9月收治的287例行ESWL治疗的肾结石患者为研究对象,对结石特征与疗效关系进行回顾性分析,比较各组行ESWL术后3个月的疗效情况。结果:本组287例患者中碎石成功221例,成功率为77.01%,结石长径<1.0cm清石率为(157/175)89.71%;结石长径在1.0cm-2.0cm清石率为(51/72)70.83%;结石长径>2.0cm清石率为(13/40)32.50%;三组清石率比较差异具有统计学意义(P<0.05)。肾盏结石组与肾盂结石组清石率(69.11%和82.93%)差异具有统计学意义(P<0.05);多发结石与单发结石清石率(60.21%和85.71%)差异具有统计学意义(P<0.05)。结论:患者肾结石长径大小、结石数量及结石位置对肾结石ESWL疗效具有重要影响。
Objective: To study the influencing factors of judging the therapeutic effect of ESWL in kidney stones. Methods: A total of 287 ESWL-treated nephrolith patients admitted from September 2006 to September 2012 in our hospital were retrospectively analyzed. The relationship between the features of stone and the curative effect was analyzed retrospectively. The efficacy of the month. Results: Of the 287 patients, 221 cases were successfully treated with gravel, the success rate was 77.01%, the rate of clear stone with long axis <1.0cm was (89/175) 89.71%, the long diameter of stone was 1.0cm-2.0cm (51/72) 70.83%. The stone diameter of> 2.0cm was (13/40) 32.50%. There was significant difference between the three groups (P <0.05). There were significant differences between the calculus group and the pyelolitholithic group (69.11% vs 82.93%) (P <0.05). The rates of clear stones (60.21% vs 85.71%) in multiple calculus and single calculus were statistically different (P <0.05). Conclusion: The length of kidney stones, the number of stones and the location of stones have an important influence on the therapeutic effect of ESWL in kidney stones.
