目的:探讨输尿管封堵器联合气压弹道碎石治疗输尿管结石的临床疗效。方法:将2011年5月至2012年11月收治的78例输尿管结石患者随机分为观察组40例和对照组38例。对照组采用气压弹道碎石术,观察组采用输尿管封堵器联合气压弹道碎石术。对比两组手术疗效、手术时间、住院时间、血尿时间、BuN和cr水平变化和不良反应发生率。结果:观察组一次性碎石率、一个月结石排净率、治疗后有效率均显著高于对照组(P<0.05);观察组需要再次手术人数明显低于对照组(P<0.05)。观察组手术时间、血尿时间、住院时间、BUN和cr水平均少于时照组(P<0.05)。观察组肾绞痛、发热、胃肠道反应等不良反应发生率明显低于对照组(P<0.05);但观察组血尿发生率明显高于对照组(P<0.05),结论:输尿管封堵器联合气压弹道碎石治疗输尿管结石既能提高碎石成功率。还能降低医疗成本。值得临床推广。
Objective: To investigate the clinical efficacy of ureteral occluder combined with pneumatic lithotripsy in the treatment of ureteral calculi. Methods: 78 patients with ureteral calculi treated from May 2011 to November 2012 were randomly divided into observation group (40 cases) and control group (38 cases). The control group was treated by pneumatic lithotripsy, and the observation group was treated by ureter occluder combined with pneumatic lithotripsy. The curative effect, operation time, hospitalization time, hematuria time, changes of BuN and Cr levels and incidence of adverse reactions were compared between the two groups. Results: The rate of disposable stones, the rate of stone removal in one month and the effective rate after treatment in the observation group were significantly higher than those in the control group (P <0.05). The number of reoperation required in the observation group was significantly lower than that in the control group (P <0.05). The operation time, hematuria time, hospitalization time, BUN and cr levels in the observation group were all less than those in the control group (P <0.05). The incidence of adverse reactions such as renal colic, fever and gastrointestinal reaction in the observation group was significantly lower than that in the control group (P <0.05), but the incidence of hematuria in the observation group was significantly higher than that in the control group (P0.05). Conclusion: The combination of pneumatic lithotripsy and ureteral stones can both improve the success rate of lithotripsy. Can reduce medical costs. Worth clinical promotion.
