术前导尿对输尿管镜置镜成功率的影响研究

Retrospective analysis of the success rate of preoperative catheterization and ureteroscopy

目的评估术前导尿对输尿管镜置镜成功率的影响。方法选取2020年10月至2023年9月期间收治的400例输尿管结石患者为研究对象,均行输尿管镜钬激光碎石术,根据术前是否导尿,将患者分为两组:观察组(导尿组)200例,对照组(非导尿组)200例。记录并分析两组患者一次性置镜成功例数、置镜手术时间、并发症发生率等。结果观察组的置镜时间为(126.35±1.55)s,明显低于对照组的(241.33±1.50)s(P<0.01);观察组的术中并发症发生率为0.5%,明显低于对照组的5.5%(P<0.05);两组的碎石时间、术中并发症发生率比较,差异均无统计学意义(P>0.05)。结论术前导尿可以缩短输尿管镜置镜时间,并且置镜成功率和安全性更高,值得临床推广。

Objective To evaluate the effect of preoperative catheterization on the success rate of ureteroscopy placement.Methods A total of 400 patients with ureteric stones admitted from October 2020 to September 2023 were selected as the study subjects,and all underwent ureteroscopic holmium laser lithotripsy.According to the preoperative catheterization,the patients were divided into two groups:200 in the observation group(catheterization group)and 200 in the control group(non-catheterization group).The number of successful cases,time of lens surgery and complication rate were recorded and analyzed.Results The placement time in the observation group was(126.35±1.55)s,which was significantly lower than that in the control group(241.33±1.50)s(P<0.01).The intraoperative complication rate(0.5%)was significantly lower than that in the control group(5.5%)(P<0.05).The difference was not statistically significant(P>0.05).Conclusion Preoperative catheterization can shorten the ime of ureteroscopy,and the success rate and safety are higher,which is worthy of clinical promotion.
