目的 分析标准通道经皮肾镜取石术与微通道经皮肾镜取石术治疗肾结石的临床疗效。方法 对我院泌尿外科2014年 6月-2015年6月收治的60例肾结石患者进行实验观察，根据不同手术方式将患者分为观察组和对照组各30例。观察 组采用微通道经皮肾镜取石术，对照组采用标准通道经皮肾镜取石术。观察两组患者的临床疗效和并发症发生情 况。结果 观察组患者的手术时间、住院时间、早期下床活动时间、住院费用明显低于对照组，两组差异有统计学 意义(P＜0.05)。两组患者并发症和结石清除率差异较小，无统计学意义(P＞0.05)。结论 在肾结石的手术治疗方 法中，微通道经皮肾镜取石术的治疗效果明显优于标准通道经皮肾镜取石术，缩短了患者的住院时间、降低了患者 住院费用、术中出血量少、减少了患者的痛苦

Objective To analyze the clinical efficacy of the standard channel percutaneous nephrolithotomy lithotripsy and percutaneous nephrolithotomy microchannel lithotripsy for the treatment of kidney stones. Methods 60 patients with kidney stones treated in our hospital urology from June 2014 to June 2015 were selected and divided into observation group and control group with 30 cases of each group depending on the surgical methods. Patients in observation group were undentwent microchannels percutaneous nephrolithotomy surgery whilc patients in control group were undent standard channel percutaneous nephrolithotomy surgery. Clinical efficacy and complications were observed and analyzed between groups. Results The patient's operation time, hospital stay, early ambulation time, hospital costs of observation group were significantly lower than those of control group, the difference was statistically significant (P <0.05). The difference of complications and stone clearance rate between two groups was not statistically significant (P>0.05). Conclusion The surgical treatment of kidney stones, the therapeutic effect of microchannel percutaneous nephrolithotomy surgery was significantly better than the standard channel percutaneous nephrolithotomy surgery, which can shorten the hospital stay, reduce hospital costs of patients, bleeding less, and reduce the suffering of patients.
