经输尿管鞘输尿管镜碎石取石治疗复杂输尿管结石的临床研究

Management of ureteral complicated calculi using ureteroscope via ureteral access sheath

摘要:

目的  探讨经输尿管鞘输尿管镜碎石取石治疗复杂输尿管结石的有效性及安全性。方法  2012年8月-2015年5月采用经输尿管鞘输尿管镜碎石取石治疗复杂输尿管结石36例，观察手术情况及术后并发症。结果  36例手术均成功，平均手术时间（53.1±26.8）min，结石清除率为100%。无发热及输尿管损伤、狭窄等并发症。结论  经输尿管鞘输尿管镜碎石取石治疗复杂输尿管结石安全有效，尤其适用于输尿管中下段较大或多发结石及石街患者，术中能保持肾盂低压，可反复进镜而不损伤输尿管，并且完全取出输尿管结石，有较好临床应用价值。

Abstract:

【Objective】 To evaluate the efficacy and safety of ureteroscope via ureteral access sheath for ureteral complicated calculi. 【Methods】 Between August 2012 and May 2015, a total of 36 patients underwent technique of ureteroscope via ureteral access sheath for ureteral complicated calculi were retrospectively analyzed. 【Results】 All cases were stone-free with one procedure, mean operating time was (53.1 ± 26.8) min, and no complications such as fever or ureteral injury happened. 【Conclusion】 Ureteroscopy via ureteral access sheath is a safe and effective option for ureteral complicated calculi, especially for large or multiple distal ureteral stones and steinstrasse. It can keep low pelvic pressure, protect ureter, and remove ureter stones completely. Thus it could be used in clinical practice.
