微通道联合负压吸引行经皮肾镜取石术治疗鹿角形肾结石的效果

Effect of percutaneous nephrolithotomyusing micro-channel combined with vacuum suction for treatment of staghorn kidney stones

目的探讨持续负压吸引在微通道经皮肾镜取石术治疗鹿角形肾结石的临床效果。方法选取2016年1月—2017年12月在我院确诊鹿角形肾结石并行经皮肾镜取石术治疗的病例138例;根据通道大小、有无负压吸引装置分为观察组和对照组,其中观察组66例,采用20F微通道联合持续负压吸引,对照组72例,采用22F标准通道,无负压吸引。比较两组的术中生命体征变化、肾盂内压力以及术后发热的发生率。结果观察组在术中血压和心率等生命体征变化、肾盂内压力以及术后发热的发生率均低于对照组,差异有统计学意义(P<0.05)。结论微通道联合负压吸引行经皮肾镜取石术治疗鹿角形肾结石可以有效降低肾盂内压力,有效维持生命体征的稳定,减少术后发热的发生率,提高手术安全性。

Objective To explore the clinical effect of percutaneous nephrolithotomy for treatment of staghorn kidney stonesusingmicro-channel combined with vacuum suction.Methods A total of 138 patientsofstaghorn kidney stones with PCNL in our hospital from January 2016 to December 2017 were included and divided into experimental group and control group according to the size of the channel and the vacuum suction device.Y-type minimally invasive dilatation drainage kit of 20F micro-channelandvacuum suctionwere used in experimental group within 66 patients.A standard channel(22F diameter)without vacuum suction was used in control group within 72 patients.The changes in vital signs,intrapelvic pressureand incidence of postoperative fever were compared between experimental and control groups.Results The vital signs variety of blood pressure and heart rate,intrapelvic pressure and incidence of postoperative fever in experimental group were lower than those in control group(P<0.05).Conclusion Micro-channel combined with vacuum suctioninpercutaneous nephrolithotomy for treatment of staghorn kidney stones could effectively maintenance of stable vital signs,reduce intrapelvic pressure and the incidence ofpostoperative fever,and improve the safety of surgery.
