目的探讨输尿管肾镜钬激光碎石术治疗输尿管结石的临床疗效和安全性。方法选取2011年1月~2014年6月我院收治的180例输尿管结石患者作为研究对象,采用随机数字表法将所选患者分为研究组和对照组,各90例,研究组采用输尿管肾镜钬激光碎石术治疗,对照组采用输尿管气压弹道碎石术治疗,随访6个月,综合比较两组患者手术时间、术中出血量、住院时间、碎石成功率、结石排净率及并发症情况。结果研究组手术时间、术中出血量、住院时间分别为(28.3±3.2)min、(30.5±11.6)m l、(5.1±1.4)d,均少于对照组(P<0.05);研究组碎石成功率、结石排净率分别为96.7%、97.8%,均高于对照组的85.6%、87.8%(P<0.05);研究组患者出现发热、严重出血、黏膜撕脱、尿外渗、输尿管穿孔等并发症发生率为6.7%,低于对照组的21.1%(P<0.05)。结论输尿管肾镜钬激光碎石术治疗输尿管结石效果确切,具有微创、操作简便、安全高效等优点,结石一次清除率高,值得临床推广使用。
Objective To investigate the clinical efficacy and safety of ureteroscopic holmium laser lithotripsy in the treatment of ureteral calculi. Methods A total of 180 patients with ureteral calculi admitted to our hospital from January 2011 to June 2014 were selected as study subjects. The patients were divided into study group and control group by random number table method, 90 cases in each group. Ureteral nephrology Holmium laser lithotripsy, the control group was treated with ureteral pneumatic lithotripsy, followed up for 6 months, a comprehensive comparison of two groups of patients operating time, blood loss, hospital stay, gravel success rate, stone removal rate and Complications. Results The operation time, intraoperative blood loss and hospital stay were (28.3 ± 3.2) min, (30.5 ± 11.6) ml and (5.1 ± 1.4) d, respectively, less than those in the control group (P <0.05) Stone success rate and stone removal rate were 96.7% and 97.8%, respectively, which were higher than 85.6% and 87.8% (P <0.05) of the control group. The patients in study group had fever, severe hemorrhage, mucosal avulsion, The incidence of complications such as ureter perforation was 6.7%, lower than 21.1% of the control group (P <0.05). Conclusion ureteroscopic holmium laser lithotripsy for the treatment of ureteral calculi exact, with minimally invasive, easy to operate, safe and efficient advantages, a clear rate of stones, worthy of clinical promotion and use.
