摘　　要：【目的】探讨后腹腔镜下输尿管切开取石术(RLU)治疗输尿管结石术后并发输尿管狭窄的危险因素。【方法】回顾性分析2016年2月至2019年8月本院收治的501例拟行RLU治疗的输尿管结石患者的临床资料,根据术后是否发生输尿管狭窄将其分为观察组(术后发生输尿管狭窄,n=26)和对照组(术后未发生输尿管狭窄,n=475)。患者术后随访1年。统计RLU术后并发输尿管狭窄的情况,采用Logistic回归分析影响RLU患者术后并发输尿管狭窄的因素。【结果】501例行RLU治疗的输尿管结石患者术后共有26例(5.19%)并发输尿管狭窄,其中21例患者为输尿管近端狭窄,5例患者为输尿管远端狭窄,剩余475例患者术后未出现输尿管狭窄。单因素分析显示,患者结石嵌顿病程、结石直径、肾积水程度是RLU术后并发输尿管狭窄的影响因素(P<0.05)。Logistic多因素分析显示,结石病程、结石直径、肾积水程度是RLU术后并发输尿管狭窄的影响因素(P<0.05)。【结论】输尿管结石患者RLU术后并发输尿管狭窄的风险高,结石病程、结石直径、肾积水程度是RLU后并发输尿管狭窄的危险因素。【Objective】To investigate the risk factors of ureteral stricture after retroperitoneal laparoscopic ureterolithotomy(RLU)in the treatment of ureteral calculi.【Methods】The clinical data of 501 patients with ureteral calculi who were treated with RLU from February 2016 to August 2019 were analyzed retrospectively.According to whether there was ureteral stenosis after operation,they were divided into observation group(postoperative ureteral stenosis,n=26)and control group(no postoperative ureteral stenosis,n=475).The patients were followed up for 1 year.The situation of ureteral stenosis after RLU was counted,and the factors affecting ureteral stenosis after RLU were analyzed by logistic regression.【Results】Total of 26 cases(5.19%)of 501 patients with ureteral calculi treated by RLU were complicated with ureteral stenosis,including 21 patients with proximal ureteral stenosis,5 patients with distal ureteral stenosis,and the remaining 475 patients had no ureteral stenosis.Univariate analysis showed that the course of stone incarceration,stone diameter and degree of hydronephrosis were the influencing factors of ureteral stenosis after RLU(P<0.05).Logistic multivariate analysis showed that the course of stone,stone diameter and degree of hydronephrosis were the influencing factors of ureteral stenosis after RLU(P<0.05).【Conclusion】The risk of ureteral stricture after RLU is high in patients with ureteral calculi.The course of stone,stone diameter and degree of hydronephrosis are the risk factors of ureteral stricture after RLU.
