经尿道气压弹道与钬激光碎石术治疗小儿下尿路结石的比较

目的探讨经尿道气压弹道与钬激光碎石术治疗小儿下尿路结石的安全性和有效性。 方法回顾性分析2016年9月至2017年8月在喀什地区第一人民医院和伽师县人民医院就诊的14例气压弹道碎石术与30例钬激光碎石术治疗的下尿路结石患儿的临床资料。 结果气压弹道组结石清除率达93％，手术时间7～45 min（22±13），术后1例因排尿困难需要尿道外口取石2次、1例因尿潴留需留置尿管。而钬激光组，一次性清石率为97％，手术时间10～50 min（26±14），术后1例排尿困难复查有残留结石，行二次经尿道钬激光碎石术后排尿通畅。两组均无其余严重并发症。两组手术时间、术后留置尿管时间、术后住院天数及并发症的比较差异无统计学意义。 结论气压弹道和钬激光碎石术治疗小儿下尿路结石均疗效好、结石清除率高、无严重并发症。

Comparative study of transurethral pneumatic cystolithotripsy and transurethral Ho: YAG laser cystolithotripsy in children with lower urinary tract stones

ObjectiveTo evaluate the efficacy of transurethral pneumatic cystolithotripsy versus transurethral Ho: YAG laser cyslithotripsy in children with lower urinary tract stones. MethodsThe clinical data of 14 children treated with pneumatic cystolithotripsy (group A) and 30 children treated with Ho: YAG laser (group B) with lower urinary trackt stones in People's Hospital of Kashgar Area and Jiashi County People's Hospital from September 2016 to August 2017 were analyzed retrospectively. ResultsThe stone free rate in group A was 93%, The mean operating time was (22±13) (range 7-45 min). Post-operatively one case needed stone extraction from the urethral outlet and one case needed catheterizasion because of urine retension. In group B, the stone free rate was 97%. The mean operating time was (26±14) (range 10-50 min). Post-operatively, one case needed second transurethral lithotripsy because of residual stone. There was no other serious complications in two groups. There was no significant difference in age, stone size, operation time, post-operative catheterizasion, hospitalization and complications between the two groups. ConclusionBoth pneumatic and Ho: YAG laser lithotripsy for lower urinary tract stones in children were safe with high clearance rate and less complications.
