筋膜扩张器协助输尿管镜钬激光治疗婴幼儿中下段输尿管结石的疗效观察

Treatment of paediatric stone disease in middle and lower ureter with fascia dilator and ureteroscopic holmium laser

目的探讨筋膜扩张器协助输尿管镜钬激光在婴幼儿中下段输尿管结石中的临床应用疗效。方法对35例婴幼儿中下段输尿管结石患儿,常规采用6.0~8.0F筋膜扩张器扩张输尿管,并行输尿管镜钬激光碎石术。结果 35例患儿中,Ⅰ期碎石成功33例(94.3%),2例(5.7%)患者有碎石块被冲入肾盂,行体外冲击波碎石术(ESWL)治愈,手术时间平均30~40 min,未出现结石残留或严重并发症。随访10~12个月未发现输尿管狭窄;泌尿系感染1例。结论临床应用筋膜扩张器配合输尿管镜钬激光治疗婴幼儿中下段输尿管结石能提高手术成功率、降低手术风险,是婴幼儿输尿管镜碎石术治疗输尿管结石理想、安全、有效的辅助手段。

Objective To evaluate the methods for treatment of paediatric stone disease in middle and lower ureter with fascia dilator and ureteroscopic holmium laser. Methods For 35 child patients with middle and lower ureteral calculi, the dilation of orifice was taken by 6.0 - 8.0 F fascia dilator, then ureteroscopic holmium laser lithotripsy followed. Results Among the 35 cases, 33 cases were the successful gravel, with a total rate of 94.3% gravel. In other two cases, the broken stones were rushed into the renal pelvis and ESWL was successfully carried. Conclusion Fascia dilator and ureteroscopic holmium laser in paediatric middle and lower ureteral calculi can improve the successful rate of operation and reduce the operation risks. It is safe and effective.
