钬激光碎石术与体外冲击波碎石术治疗输尿管不同部位结石的临床研究

目的比较钬激光碎石术（LL）与体外冲击波碎石术（ESWL）治疗不同部位输尿管结石的优劣。方法ESWL组66例患者采用体外冲击波术，LL组66例患者采用钬激光碎石术。结果LL组患者上段结石残留率明显高于ESWL组，中下段结石残留率明显低于ESWL组，LL组患者平均治疗时间明显短于ESWL组；LL组患者血尿、膀胱刺激、结石上移、输尿管穿孔发生率明显高于ESEL组，肾绞痛和发热发生率明显低于ESWL组（P〈0．05）。结论上段结石ESWL效果更好，中下段结石LL疗效更佳。

Clinical Study of Holmium Laser Lithotripsy and Extracorporeal Shock Wave Lithotripsy for Treating Different Parts of Ureteral Stones

Objective To compare the pros and cons of holmium laser lithotripsy （LL） and extracorporeal shock wave lithotripsy （ESWL） treating in different parts of ureteral stones. Methods All of 66 cases in ESWL Group were treated by extracorporeal shock wave lithotripsy and 66 cases in LL Group were treated by holmium laser lithotripsy. Results The upper stone residual rate of LL Group 12.5% was significantly higher than ESWL Group, the middle and lower stone residual rate of LL Group was significantly lower than ESWL Group. The average hospital stay time of LL Group was longer than ESWL Group. The complications rate of hematuria, bladder irritation, move stones, ureteral perforation in LL Group were significantly higher than ESWL Group, and complications rate of renal colic and fever were lower than ESWL Group（P〈0.05）. Conclusion ESWL had better effects in upper stones and LL had better effects in middle and lower stones.
