摘要目的 探讨倒置排石床在治疗肾下盏结石中的作用.方法 2006年3月至2008年9月,收治的36例肾下盏结石患者,其中结石直径>4 mm且<2 cm者13例,进行体外冲击波碎石术(ESWL)同时配合倒置排石床治疗,直径≤4 mm且≥2 mm的单纯肾下盏结石或输尿管镜钬激光碎石术及后下盏残石23例,仅进行倒置排石床治疗.3个月后复查尿路平片,了解结石排尽情况.结果 所有36例患者均顺利完成排石床排石治疗,倒置排石过程中未出现严重的心脑血管意外,3个月复查结石排净率83.3%(30/36),残石率16.7%(6/36).结论 采用倒置排石床可以提高肾下盏结石排石率,可作为结石微创治疗的辅助手段.

abstractsObjective To investigate the effect of inversion-table in the treatment of lower pole renal stones.Methods From March 2006 to September 2008,36 patients with lower pole renal calculi were treated by inversion-table,13 cases with stone diameter from 4 mm to 20 mm received extracoporeal shock wave lithotripsy (ESWL) combined with inversion-table treatment and other 23 cases with stone diameter from 2 mm to 4 mm received inversion-table treatment alone.Results All of 36 cases underwent inversion-table treatment successfully and no one had cardio-cerebral accident.After following up 3 months,the radiologically documented complete stone clearance rate at 3 months group was 83.3%.Conclusion Inversion-table treatment is a safe and valuable adjunct in assisting passage of lower pole renal stone fragments after mini-invasive treatment of stone and can improve stone-free rate.
