【摘要】 目的 探讨负压吸引鞘碎石治疗嵌顿性输尿管结石的疗效及安全性。方法 输尿管嵌顿结石病人98例。根据手术方式将其分为两组，研究组45例，采用负压吸引鞘输尿管碎石取石治疗，对照组53例，采用传统输尿管镜碎石取石治疗，比较两组病人的临床疗效。结果 研究组病人的手术时间及肾盂内压均少于(低于)对照组，结石清除率高于对照组，差异有统计学意义(P<0.05);术前两组病人相关感染指标比较差异无统计学意义(P>0.05),术后第1天研究组相关感染指标变化低于对照组，差异有统计学意义(P<0.05);研究组病人术后并发症发生率低于对照组，差异有统计学意义(P<0.05)。结论 负压吸引鞘输尿管碎石取石治疗嵌顿性输尿管结石疗效显著，可提高结石清除率，减轻手术炎性反应，减少术后并发症。更多还原

【Abstract】 Objective To investigate the efficacy and safety of negative pressure suction sheath lithotriptic for incarcerated ureteral calculi.Methods Ninety-eight patients with ureteral embedded stones admitted to our hospital were selected for the study.They were divided into 2 groups according to the differences in surgical methods.Forty-five patients in the study group were treated with negative pressure suction sheath ureteral lithotripsy, while 53 patients in the control group were treated with conventional ureteroscopic lithotripsy, comparing the clinical efficacy and other differences between the two groups.Results The operation time and renal pelvis pressure in the study group were lower than those in the control group, and the stone clearance rate was higher than that in the control group(P<0.05).There was no difference in the relevant test indexes between the two groups before surgery(P>0.05),while the relevant test indexes in the study group improved significantly after surgery than those in the control group(P<0.05).Postoperative day 1,the complication rate of patients in the study group was significantly lower than that of the control group(P<0.05).After surgery, the prognosis of patients in the study group was significantly better than that of patients in the control group(P<0.05).Conclusion The efficacy of negative pressure suction sheath ureterolithotripsy in patients with incarcerated decrease the occurrence of postsurgical complications, which not only significantly improves the stone removal rate, but also reduces the inflammatory response of patients to surgery and ultimately improves their prognosis.更多还原
