超声引导经皮肾镜术中不置输尿管导管的安全性探讨

目的 探讨超声引导经皮肾镜取石术中(PCNL)不置输尿管导管的可靠性及安全性.方法 采用PCNL 治疗合并一定肾积水的肾和输尿管上段结石120 例,入选病例随机分为2 组,A 组(不使用输尿管导管)60 例,B 组(使用输尿管导管)60例,两组性别、年龄、结石大小、结石停留时间、同侧肾盂分离距离无统计学差异.统计麻醉时间、手术时间、住院时间、医疗费用、结石清除率、术后发热、术中失血量等指标.结果 2 组平均手术时间、结石清除率、住院时间、术中失血量无显著性差异(P>0.05);麻醉时间、医疗费用、术后发热A 组显著低于B 组(P<0.05).结论 对于肾盂分离>10 mm 的肾积水患者,超声引导PC原NL不置输尿管导管是一种经济、可靠、安全的方法.

The security explore in percutaneous nephrolithotripsy under B-type ultrasound without ureteral catheter

Objective To explore and evaluate the efficacy and safety of percutaneous nephrolithotomy under ultrasonic guidance without ureteral catheter.Methods One hundred and twenty cases diagnosed as renal or upper ureteral calculi were randomly divided into two groups:A(unstented group,n= 60)and B(stented group,n= 60).There were no statistical significant differences in sex,age,calculi size,calculi stay time,pelvis separation between the groups.Anesthesia time,operative time,hospital stay,cost,calculi clearance rate,postoperative fever,blood loss were compared in both groups.Results No statistical significant differences were found with the time of operation,stone clearancerate,hospital stay,blood loss between the two groups.However,group A had more advantages in anesthesia time,cost,postoperative fever.Conclusion Percutaneous nephrolithotomy under ultrasonic guidance without ureteral catheter is an economy,effective and safe treatment of renal or upper ureter.
