探讨体外冲击波碎石治疗肾结石疗效的影响因素

目的研究分析肾结石体外冲击波碎石术(ESWL)的临床疗效和影响因素。方法对2011年5月至2013年在我院采用ESWL治疗的400例肾结石患者病例资料进行回顾性分析。结果 400例碎石的成功率为78.0%。结石直径<2.0 cm,2.0³.0cm及>3.0 cm的肾结石,肾结石体外冲击波碎石后清石率(4个月后)差异均有统计学意义(P<0.05);两组在肾盂结石与肾盏结石方面比较后成功率差异有统计学意义(P<0.05);单发结石与多发结石两组成功率比较差异有统计学意义(P<0.05),其他因素对成功率影响均无统计学意义(P>0.05)。结论结石位置、大小和数量是影对ESWL治疗肾结石的疗效有重要影响作用。

To Investigate the Effect of Extracorporeal Shock Wave Lithotripsy Works for the Treatment of Renal Calculi Curative Effect Factors

Objective To study renal calculi extracorporeal shock wave lithotripsy （ESWL） in clinical efficacy and influencing factors. Methods 400 cases of renal calculi patients clinical data in 2011 May-2013 in treated with ESWL in our hospital were retrospectively analyzed. Results 400 cases of lithotripsy success rate was 78%. Stone diameter〈2.0 cm, 2.0-3.0 cm and〉3 cm kidney stones, kidney stones after extracorporeal shock wave lithotripsy kiyoshi rate （4 months） showed significant differences（P〈0.05）;the two group in the pelvis calculi and renal calyceal stones more successful rate difference was statistically significant（P〈0.05）;single stone and multiple calculi in two success rate of group had significant difference（P〈0.05）, other factors have no significant influence on the success rate（P〉0.05）. Conclusion Stone location, size and number is have important influence on the effect of ESWL treatment of renal calculi.
