单通道负压吸引鞘在经皮肾镜中的临床应用

目的探讨单通道负压吸引鞘在经皮肾镜治疗肾结石的安全性和有效性。 方法回顾性分析北京平谷区医院和哈尔滨工业大学附属黑龙江省医院从2018年1月至2019年11月住院期间的111例肾结石患者,一组行负压吸引鞘（Y型鞘）经皮肾镜手术56例（负压组）,一组行常规鞘（常压鞘）经皮肾镜手术55例（常压组）。分别记录两组的手术时间、肾盂压力、术中患者出血量、术后结石清除率、术中术后并发症等临床资料,对两组患者的临床资料进行分析和总结。 结果观察组的手术时间、肾盂压力明显低于对照组并且差异有统计学意义（P<0.05）。观察组结石清除率,术中出血量,术后出血发生率两组比较,两组差异无统计学意义（P>0.05）,术后发热发生率,术后总并发症发生率、术后第1天降钙素原（PCT）值、C反应蛋白（CRP）值明显低于对照组且差异有统计学意义（P<0.05）。 结论单通道负压吸引鞘在经皮肾镜中应用安全性高,并发症少。

Application of percutaneous nephrolithotomy with negative pressure suction in one channel

ObjectiveTo explore the safety and efficacy of negative pressure suction in percutaneous nephrolithotomy. MethodsThe data of all patients were diagnosed with renal stones between January, 2018 and November, 2019 were analyzed retrospectively. All patients were divided into two groups. The experimental group included 56 patients and the control group included 55 patients. The experimental group was operated by percutaneous nephrolithotomy with negative pressure suction and the control was done by routine percutaneous nephrolithotomy. Operative time, stone-free rate, renal pelvis pressure, complications were compared between the two groups. ResultsThe renal pelvis pressure and operate time in the experimental group are less than those in the control group (P<0.05). There are no difference between two groups in the stone-free rate, blood loss volume the rate of blood loss (P>0.05). The rate of fever and total complications, the level of PCT and CRP in the experimental is less than the control group. ConclusionsIt is safe and effective that the negative pressure is used in the percutaneous nephrolithotomy.
