摘要
目的探讨微创经皮肾穿刺联合输尿管镜下碎石术治疗婴幼儿肾盂结石的疗效和安全性。方法 8～36月龄婴幼儿单侧肾盂结石10例,全麻后经尿道从患侧输尿管内逆行置入F4输尿管导管;从11肋间隙与腋后线相交处,在B超或C臂X线机引导下穿刺至肾盂,以能量密度120mJ/cm2,脉冲频率5～10HzU100倍频双波长脉冲激光将结石粉碎,从输尿管导管冲出碎石,留置F4～F6单"J"管7～10d。结果 10例患者均一期穿刺取石成功,所有患者均采用单通道,结石1期清除率100.0%。1例患儿因结石位于肾盂和肾下盏采用C臂X光机定位,9例采用B超引导下定位。手术时间30～50min,平均手术时间40min。无输血、尿外渗病例,无开放手术。结论微创经皮肾穿刺联合输尿管镜下U100倍频双波长脉冲激光碎石术治疗婴幼儿肾结石安全、有效。
Objective To evaluate the efficacy and safety of mini-invasive percutaneous nephrolithotripsy（MPCNL）for urolithiasis infants with age less than 3 years.Methods The infants aged 8-36 months with unilateral kidney stones were operated with following methods：after anesthesia to insert F4 ureteral catheter transurethrally,then puncture it from the intersection of 11th intercostal space and posterior axillary line to pelvis renalis under X-ray or B-ultrasound.After that,shattered the stones by frequency-doubled-double pulse laser with 120 J/cm^2 energy and 5-10 Hz U100.In the end,flushed the stones via ureteral catheter and retented the F4-F6 mono-J tube for 7 to 10 days.ResultsTen cases were stone-free after a single session of percutaneous nephrolithotripsy （1 case under X-ray and 9 under B-ultrasound）,the surgical operation time was 30-50 min,there was no blood transfusion or excessive intraperitoneal extravasation of urine,no one was converted to open surgery.ConclusionsMPCNL is safe and effective for renal calculi of infants.
