两种微创治疗技术经尿道输尿管镜下治疗小儿输尿管囊肿合并结石的比较

Comparative Research on Transurethral Ureteroscopic Microinvasive Treatment of Ureterocele with Calculi in Pediatrics

目的探讨两种经尿道输尿管镜下微创化治疗小儿输尿管囊肿合并结石的方法有效性。方法回顾性分析2011年3月至2015年2月,小儿输尿管囊肿合并结石患者55例的临床资料。按入院先后顺序分为两组:常规组,患者18例,采用经尿道输尿管镜下电切联合超声弹道碎石术治疗;激光组,患者37例,采用2μm激光汽化切除联合碎石术治疗。比较两组患者手术时间、留置导尿时间、术后住院时间和并发症发生率。结果激光组囊肿切除时间、总体手术时间、留置导尿时间明显短于常规组(P<0.01),两组患者的碎石时间、术后住院时间和并发症发生率比较,差异无显著意义(P>0.05)。结论经尿道输尿管镜下2μm激光汽化切除联合碎石术治疗小儿输尿管囊肿合并结石具有手术时间短、出血少、操作安全简便等优点,是一种安全、可靠的微创手术方法。

Objective To compare the effectiveness of 2 microinvasive methods in treating pediatric ureteroceles with calculi via ureteroscopy.Methods A retrospective analysis on 18 patients（ the routine group） given electroscission plus lithotripsiesand 37 patients（ the laser group） given 2 μm laser vaporesections and lithotripsies was made to compare the operation time,catheterization period,hospitalization length after operation and postoperative complication rate.Results Compared with the routine group,the laser group had shorter cystic resection time,whole operation length and catheterization period,and the differences were statistically significant（ P〈0. 01）. There was no obvious difference in lithotripsy time,hospitalization length after operation,and postoperative complication rate between these 2 groups（ P〉0. 05）.Conclusions Being characterized by little blood loss,high safety,convenient operation and rare complications,transurethral 2 μm laser treatment via ureteroscopy was a superior micro-invasive surgery method for pediatrics ureterocele with calculi.
