输尿管镜钬激光碎石术与体外冲击波碎石术治疗输尿管结石的疗效比较

目的 观察输尿管镜钬激光碎石术与体外冲击波碎石术治疗输尿管结石的临床疗效。方法 选取2015年1月~2018年10月在余江县人民医院治疗的输尿管结石患者72例，采用随机数字表法分为对照组和观察组，各36例。对照组采用体外冲击波碎石术治疗，观察组采用输尿管镜钬激光碎石术治疗，比较两组清石率、手术时间、住院时间以及并发症（血尿、输尿管水肿、结石移位）发生情况。结果 观察组结石直径≥1 cm清石率为92.30%，高于对照组的85.71%，差异有统计学意义（P＜0.05）；观察组结石直径＜1 cm清石率为91.30%，与对照组的90.90%比较，差异无统计学意义（P＞0.05）；观察组结石直径≥1 cm、＜1 cm手术时间均短于对照组，差异有统计学意义（P＜0.05）；观察组并发症发生率为5.56%，低于对照组的23.08%，差异有统计学意义（P＜0.05）。结论 输尿管镜钬激光碎石术治疗输尿管结石手术时间短，并发症少，且对于结石直径＞1 cm者效果更优。

Comparison of Ureteroscopic Holmium Laser Lithotripsy with Extracorporeal Shock Wave Lithotripsy for Ureteral Calculi

Objective To observe the clinical efficacy of ureteroscopic holmium laser lithotripsy and extracorporeal shock wave lithotripsy for ureteral stones. Methods 72 patients with ureteral calculi treated in Yujiang County People’s Hospital from January 2015 to October 2018 were selected and divided into a control group and an observation group by random number table method, with 36 cases in each group. The control group was treated with extracorporeal shock wave lithotripsy, and the observation group was treated with ureteroscopy holmium laser lithotripsy. The two groups were compared for the rate of lithotripsy, operation time, length of hospital stay, and complications (hematuria, ureteral edema, and stone displacement). Results The clear stone rate of stones with a diameter of ≥1 cm in the observation group was 92.30%, which was higher than the 85.71% of the control group,the difference was statistically significant (P<0.05).The stones with a diameter of <1 cm and the rate of clear stones were 91.30%. Compared with 90.90% of the control group, the difference was not statistically significant (P>0.05). The stones in the observation group with a diameter of ≥1 cm and <1 cm were shorter than the control group,the difference was statistically significant (P<0.05); the incidence of complications in the observation group was 5.56%, which was lower than 23.08% in the control group,the difference was statistically significant (P<0.05).Conclusion Ureteroscopy holmium laser lithotripsy for ureteral calculi has a shorter operation time, fewer complications, and is more effective for those with a stone diameter＞1 cm.
