微创经皮肾镜取石术治疗输尿管上段结石合并肾积脓效果观察

Effect observation of minimally invasive percutaneous nephrolithotomy in the treatment of upper ureteral calculi combined with pyonephrosis

目的:探讨输尿管上段结石合并肾积脓应用微创经皮肾镜取石术治疗的临床效果。方法:选取输尿管上段结石合并肾积脓62例为研究对象,随机分为2组,观察组(n=31)采取微创经皮肾镜取石术治疗,对照组(n=31)采取经皮肾镜分期取石术治疗,比较两组患者的治疗效果。结果:两组患者手术均一次取石成功,观察组结石清除率为93.5%,对照组为96.8%,两组比较差异无统计学意义(P>0.05)。两组术中出血量比较差异无统计学意义(P>0.05);观察组手术时间和住院时间明显短于对照组,且其住院费用少于对照组,组间比较差异有统计学意义(P<0.01)。术后12个月随访结果显示,观察组和对照组并发症发生率分别为9.7%和12.9%,两组比较差异无统计学意义(P>0.05)。结论:输尿管上段结石合并肾积脓采用微创经皮肾镜取石术治疗,取石成功率高,术后并发症少,可有效减少住院费用。

Objective： To explore the clinical efficacy of microinvasive percutaneous nephrolithotomy in the treatment of ureteral calculi combined with pyonephrosis. Methods： 62 cases of ureteral calculi with renal accumulation were selected. They were randomly divided into two groups,the observation group（ n = 31）was treated by microinvasive percutaneous nephrolithotomy and the control group（ n = 31） was treated by percutaneous nephrolithotomy staging. The treatment effect of two groups of patients was compared.Results： The patients in both groups were operated on successfully. The stone clearance rate was 93.5% in the observation group and 96.8% in the control group. There was no significant difference between the two groups（ P〈0. 05）. The amount of blood loss between the two groups was no statistically significant difference（ P〈0.05）. The operation time and hospitalization time of the observation group were significantly shorter than that of the control group,and the hospitalization cost was less than that of the control group,and the difference between the two group was statistically significant（ P〈0. 01）. Observation group were followed up for 12 months after surgery,and the incidence of complications was 9. 7%,compared with12.9% in the control group,and there was no statistically significant difference between the two groups（ P〈0.05）. Conclusion： The treatment of nephrostasis of ureteral calculi by microinvasive percutaneous nephrolithotomy was high stone success rate,less postoperative complications,can effectively reduce the cost of hospitalization.
