Objective To analyze the clinical effects of micro-channel percutaneous nephrolithotomy and standard channel percutaneous nephrolithotomy.Methods 118 patients with ureteral calculi in our hospital from May 2010 to May 2014 were selected and divided into micro-channel percutaneous nephrolithotomy group (MCPN) and standard channel percutaneous nephrolithotomy group (SCPN) according to the surgical approach.Observed and compared changes of each indicator in two groups before and after surgery and postoperative recovery.Results The operative time,flushing water volume and operation bleeding of SCPN group were (83.89±11.04)min,(14900±1800)ml,(68.54±8.10) ml respectively,those of MCPN group were (101.66±12.56)min,(21000±1400)ml,(58.28±6.90)ml respectively.After treatment,the level of Scr in MCPN group significantly lowered,with shorter hospital stay and less surgery cost,with statistically significant differences (P＜0.05).There were no statistically significant differences in calculi clearance and complication rate (postoperative bleeding,embolization,perforation,sepsis and so on) (P＞0.05).Conclusions Micro-channel percutaneous nephrolithotomy for upper ureteral calculi has good clinical efficacy,the type of actual operation can be selected according to the size of calculi.%目的 分析微通道经皮肾镜取石术和标准通道经皮肾镜取石术的临床效果.方法 选择2010年5月至2014年5月在我院接受治疗的输尿管结石患者118例,根据手术方式不同将所选病例分为微造瘘取石术组和标准取石术组,观察并比较两组患者手术前后各项指标以及术后恢复情况.结果 标准取石术组患者手术时间、冲水量以及术中出血量分别为(83.89±11.04)min、(14900±1800)ml、(68.54±8.10)ml,微造瘘取石术组患者分别为(101.66±12.56)min、(21000±1400)ml、(58.28±6.90)ml.与标准取石术组患者比较,微造瘘取石术组术后Scr明显降低,住院时间短,手术费用少,差异有统计学意义(P＜0.05);但两组结石清除率无统计学差异(P＞0.05);术后出血、介入栓塞、结石穿孔、脓毒血症等现象,两组差异无统计学意义(P＞0.05).结论 微通道经皮肾镜取石术治疗输尿管上段结石具有良好的临床效果,实际操作中可根据结石大小选择手术类型.
