术前免留置双J管一期输尿管软镜治疗肾结石的应用效果

Application efficacy of stage Ⅰ flexible ureteroscopic surgery for treating kidney calculi with non-indwelling double J ureteral stent before operation

目的观察术前免留置双J管一期输尿管软镜治疗肾结石的临床疗效及安全性。方法选取行输尿管软镜治疗的肾结石患者84例,按照随机数字表法分为研究组42例和对照组42例,研究组术前免留置双J管,对照组术前留置双J管1周。观察两组患者手术指标、术后恢复情况及并发症发生率。结果研究组输尿管软镜鞘置入成功率为80.95%(34/42),低于对照组的95.23%(40/42)(P<0.05),但研究组术后住院时间短于对照组(P<0.05)。研究组输尿管软镜进镜成功率、手术时间、结石清除率及术后并发症发生率与对照组比较,差异均无统计学意义(P>0.05)。结论对于术前检查输尿管无明显狭窄的肾结石患者,术前免留置双J管一期输尿管软镜治疗效果安全、有效,可缩短患者术后住院时间。

Objective To observe the clinical efficacy and safety of stageⅠflexible ureteroscopic surgery for treating kidney calculi with non-indwelling double J ureteral stent before operation. Methods A total of 84 patients with kidney calculi undergoing flexible ureteroscopic surgery were divided into 42 cases in the study group and 42 cases in the control group according to the random number table method. The study group received non-indwelling double J ureteral stent before operation,and the control group received non-indwelling double J ureteral stent for one week before operation. The indices of operation,postoperative recovery and incidence rate of complications were observed in both groups. Results The success rate of flexible ureteroscopic insertion with a ureteral access sheath in the study group was 80. 95%（ 34/42）,which was lower than that in the control group[95. 23%（ 40/42）; P〈0. 05]. The postoperative hospital stay in the study group was shorter than that in the control group（ P〈0. 05）. No significant difference was found in the success rate of flexible ureteroscopic insertion,duration of operation,stone-free rate or incidence rate of postoperative complications between the study group and the control group（ P〈0. 05）.Conclusion For kidney calculi patients without obvious ureteral stricture confirmed before operation,it is safe and effective to use non-indwelling double J ureteral stent before stage Ⅰ flexible ureteroscopic surgery,which can reduce the postoperative hospital stay of the patients.
