可弯曲负压吸引鞘联合输尿管软镜治疗2~3cm上尿路结石

Application of Flexible Negative Pressure Ureteral Access Sheath Combined With Flexible Ureteroscope in the Treatment of 2-3cm Upper Urinary Tract Stones

目的探讨可弯曲负压吸引鞘联合输尿管软镜治疗上尿路较大结石(2~3 cm)的效果。方法回顾性分析2021年9~11月应用可弯曲负压吸引鞘联合F_(7.5)一次性输尿管软镜治疗上尿路较大结石16例资料。肾结石14例,结石大小2.4~3.2 cm,(2.50±3.66)cm;输尿管上段结石2例,大小分别为2.0 cm、2.4 cm。结果手术均顺利完成,未出现大出血、发热、感染性休克、输尿管石街形成等严重并发症。术后第3天复查CT,14例无结石残留,2例肾下盏结石残留0.6 cm,体外冲击波碎石排出。结论可弯曲负压吸引鞘联合输尿管软镜治疗2~3 cm上尿路结石可行且有效。

Objective To report the feasibility,safety,and effectiveness of flexible negative pressure ureteral access sheath combined with flexible ureteroscope lithotripsy in the treatment of 2-3 cm upper urinary tract calculi.Methods A retrospective analysis of 16 patients with 2-3 cm upper urinary tract calculi,which were treated by using a F_(7.5) negative pressure ureteral access sheath combined with flexible ureteroscope lithotripsy in our hospital from September to November 2021,was reviewed.There were 14 cases of kidney stones,with a size of 2.4-3.2 cm(mean,2.50±3.66 cm),and 2 cases of upper ureteral stones with sizes of 2.0 cm and 2.4 cm,respectively.Results The operation was completed in all the patients.There were no serious complications,such as hemorrhage,fever,septic shock,or ureteral stone formation during and after the operation.CT re-examination on the third day after operation showed that 14 cases had no residual stones.Two cases had residual stones of 0.6 cm in the lower renal calyx,and extracorporeal shock wave lithotripsy was used for removal.Conclusion Flexible negative pressure ureteral access sheath combined with flexible ureteroscope lithotripsy for 2-3 cm upper urinary tract calculi is a feasible and effective method.
