目的:分析泌尿外科输尿管软镜治疗肾结石术后结石残留的影响因素,并提出相关预防措施。方法:回顾性分析2014年1月~2016年12月行输尿管软镜治疗的肾结石患者临床资料,根据术后是否残留结石将其分为残留组与无残留组,单因素及Logistic多因素回归分析术后结石残留原因。结果:残留组与无残留组在结石≥2cm(71.11%vs.58.13%)、结石负荷>400mm2(42.22%vs.28.12%)、手术时间>100min(36.67%vs.23.12%)、结石部位(下盏比例55.56%vs.13.75%)、结石成分(一水草酸钙结石比例66.67%vs.31.25%)方面比较差异有统计学意义(P<0.05);Logistic回归分析显示输尿管软镜术后结石残留独立危险因素包括结石负荷、结石部位、结石成分。结论:肾结石患者经输尿管软镜治疗后结石残留与结石部位、结石负荷等密切相关,建议熟悉掌握输尿管软镜处理适应证,针对可能导致结石残留因素采取相应措施。
OBJECTIVE: To analyze the influencing factors of residual ureteral ureteral calculi after ureteroscopic soft-lens surgery and to provide relevant preventive measures. Methods: The clinical data of patients with renal calculus underwent ureteroscopic treatment from January 2014 to December 2016 were retrospectively analyzed. According to the residual stones after operation, they were divided into residual group and non-residual group, and single factor and Logistic regression Analysis of postoperative causes of stones. Results: There was no significant difference between the residual group and the no residual group in the patients with stone ≥2cm (71.11% vs.58.13%), stone load> 400mm2 (42.22% vs.28.12%), operation time> 100min (36.67% vs.23.12% (55.56% vs.13.75% in the lower cup), and the stone composition (66.67% vs.31.25%, respectively) was statistically significant (P <0.05). Logistic regression analysis showed that the ureteral calculi Residual independent risk factors include stone load, stones, stones composition. Conclusion: Residual calculi in patients with renal stone after ureteroscopic treatment are closely related to the location of stone and stone load. It is suggested that patients with ureteral calculi should be familiar with the indication of ureteroscopic treatment and take corresponding measures for the possible causes of residual stones.
