体外冲击波碎石治疗肾及输尿管结石的疗效分析

目的 总结我院15年来体外冲击波碎石治疗肾及输尿管结石的经验及体会。方法 按美国食品与药品管理局(FDA)标准对肾结石进行分类，按输尿管结石部位分类及逆行插管，急诊体外冲击波碎石(ESWL)和手术发现，同时对肾结石的复发和ESWL与高血压的关系作一总结。结果 肾结石治疗成功率：A类为91．2％，B类为86．5％，C类为72．3％，输尿管结石治疗成功率为84．5％。逆行输尿管插管配合ESWL可提高治疗的成功率。1．1％的输尿管结石ESWL失败需外科手术治疗。肾结石复发率为6．1％，高血压发生率为7．9％。结论 体外冲击波碎石是肾及输尿管结石首选的治疗方法。

Analysis of the ESWL treatment for patients with urinary calculi

Objective To summarize our experiences in treatment of patients with urinary calculi. Methods The kidney stones were sorted by FDA standard .The ureteric stone was sorted by its site and retrograde pyelography. At the same time, we summerized the recurrence of kidney stone and its relationship between extracorporeal shock ware lithotripsy (ESWL) and hypertension. Results The efficacy for type A kidney stone was 91.2%, that for type B 86.5% and type C 72.3%, the successful rate of treatment for ureteric stone was 84.5%. Combined retrograde pyelography and ESWL could improve the efficacy. If ESWL failed, the ureteric stone could still be removed by operation (1.1%). The rate of recurrence of kidney stone was 6.1% and the incidence of hypertension reached 7.9%. Conclusion ESWL is the method of choice in treatment of urinary calculi.
