To compare the effectiveness and safety of pneumatic and holmium:YAG laser lithotripters in the treatment of pediatric ureterolithiasis.
Medical records of patients treated using pneumatic (PL) (n = 29) or laser (LL) (n = 35) lithotripter between 2009 and 2011 were retrospectively analysed. The patients were evaluated with respect to age, gender, stone size, complications, and stone-free rates 1 month after the operation.
For the PL and LL groups, mean ages (8.8 ± 3.4 and 8.3 ± 3.5 years), male/female ratios (19:10 and 22:13) and stone locations were similar (p > 0.05). Mean stone sizes were 55.6 mm2 and 47.6 mm2 in the PL and LL group, respectively, with no statistically significant difference (p = 0.850). Mean operative times were 20.5 min in the PL group and 25.2 min in the LL group, with a statistically significant difference (p = 0.020). Stone-free rates 1 month after intervention were 79% in the PL group and 97% in the LL group (p = 0.022). Stone migration was detected in the PL group (n = 6) and in the LL group (n = 1). No major complication was found in either group.
In the ureteroscopic treatment of pediatric ureterolithiasis, both pneumatic and laser lithotripters are effective and successful. However, laser lithotripsy has a higher stone-free rate and lower complication rate.
比较气动和钬激光碎石器治疗小儿输尿管结石的疗效和安全性。
回顾性分析 2009 年至 2011 年间使用气动（PL）（n = 29）或激光（LL）（n = 35）碎石器治疗的患者的病历。对患者的年龄、性别、结石大小、并发症以及术后 1 个月的结石清除率进行评估。
PL 和 LL 组的平均年龄（8.8 ± 3.4 和 8.3 ± 3.5 岁）、男女比例（19:10 和 22:13）和结石位置相似（p > 0.05）。PL 和 LL 组的平均结石大小分别为 55.6 mm2 和 47.6 mm2，差异无统计学意义（p = 0.850）。PL 组的平均手术时间为 20.5 分钟，LL 组为 25.2 分钟，差异有统计学意义（p = 0.020）。干预后 1 个月的结石清除率分别为 PL 组 79%和 LL 组 97%（p = 0.022）。PL 组（n = 6）和 LL 组（n = 1）均发现结石迁移。两组均未发现严重并发症。
在小儿输尿管结石的输尿管镜治疗中，气动和激光碎石器均有效且成功。然而，激光碎石术具有更高的结石清除率和更低的并发症发生率。
