无管化微创经皮肾镜取石术治疗上尿路结石31例

目的探讨无管化微创经皮肾镜取石术治疗上尿路结石的可行性和安全性。方法回顾性分析31例无管化微创经皮肾镜取石术的临床资料。结果 31例均顺利完成手术。术后发现残留结石1例,经体外冲击波碎石术（ESWL）治疗后残留结石排出,本组取净结石率为96.8%。手术时间34-56 min,平均42.8 min。术后2例需要输血,其中1例进行高选择性肾动脉介入治疗止血。术后住院3-7 d,平均4.3 d。结论选择性地对微创经皮肾镜取石术进行无管化处理,是一种安全、可行的处理方法,值得临床推广应用。

Tubeless minimally invasive percutaneous nephrolithotomy in the treatment of upper urinary tract calculi

Objective To explore the efficacy and safety of tubeless minimally invasive percutaneous nephrolithotomy（ mPCNL） in the treatment of upper urinary tract calculi. Methods A retrospective analysis was performed on clinical data of 31 cases of tubeless mPCNL. Results The operations in 31 cases were successfully completed.Residual stones was found in one case,the stones were eliminated after extracorpoveal shock wave lithotripsy（ ESWL）treatment. The stone free rate was 96. 8%. The operation time was 34 - 56 min,with an average of 42. 8 min. Blood transfusion after operation were in 2 cases,in which one case received highly selective renal artery embolization and got stopping bleeding. The postoperative hospitalization time was 3 - 7 d,with an average of 4. 3 d. Conclusion The tubeless of mPCNL was safe and efective when the patients are selected by certain criteria,it is worthy of clinical application.
