体外冲击碎石治疗输尿管结石伴肾绞痛

Ureteral Calculus Combined with Renal Colic Treated with Emergency ESWL

目的探讨ESWL在输尿管结石伴肾绞痛时的治疗效果。方法应用HX～902型和HK～ESWL～Ⅵ型体外冲击波碎石机治疗输尿管结石伴肾绞痛198例,冲击能量8～13kV,频率60次/min,次数300～2500次。结果碎石1次成功者158例,占79.8%;2次成功22例,占11.1%;3次成功者10例,占5.0%。其中,8例经3次碎石结石,仍大部分残存,为无效,占4.0%,碎石总有效率为95.5%。结论输尿管结石致肾绞痛的患者,由于输尿管管壁的肿胀和炎症尚轻,加上蠕动增强,使管壁或管腔与结石之间形成一定的流体界面,能为碎石发挥充分的治疗效应。因此,急诊ESWL应视为输尿管结石伴肾绞痛的首选治疗方法。

Objective To study the efficacy of ureteral calculus combined with renal colic treated with ESWL. Methods 198 cases of ureteral calculus combined with renal colic were treated with HX-902 and HK-ESWL-VI lithotripter, impulse energy was 8～13 kV, frequency was 60 bpm, total times was 300～2500. Results The stone -free cases after first ESWL was 158, took up 79.8%, and the second retreatment cases was 22, took up 11.1%, the third retreatment cases was 10,took up 5%, total stone-free rate was 95.95%. Conclusion For the patients of urteral calculus combined with renal colic, ureteral paries swell up and inflammation was little, and ureteral wriggiedstrengthened, liquid interface became between ureteral paries or cavity and calculus, it could improve treatment efficacy, so ESWL might be the preferred emergency method to treat ureteral calculus combined with renal colic.
