We aimed to compare the effectiveness of 15- and 30-W holmium:yttrium-aluminum-garnet (Ho:YAG) laser devices used in the treatment of pediatric kidney stones. Eighty-six consecutive pediatric patients who underwent retrograde intrarenal surgery (RIRS) between February 2010 and August 2020 were enrolled in the study. After exclusion criteria were applied, the data of 79 children were evaluated retrospectively. Patients were divided into two groups according to the laser device power of 15 W (Group 15: = 30) and 30 W (Group 30: = 49). The groups were compared according to demographic characteristics, stone feature, and clinical efficacy. The age, gender, height, weight, and stone characteristics were similar between the groups. The mean operation time was shorter in Group 30. The stone-free rate after the first RIRS session (SF) was 66.7% in Group 15 and 83.3% in Group 30. The SF for 20-mm or larger kidney stones was found to be 0% in Group 15 and 62.5% in Group 30. However, there was no statistically significant difference between the two groups in terms of stone-free rate. In pediatric kidney stone treatment, 30-W Ho:YAG laser devices should be preferred as they shorten the operation time compared with 15-W devices and provide the final stone-free status with fewer procedures, especially in large kidney stones.
我们旨在比较 15W 和 30W 钬：钇铝石榴石（Ho:YAG）激光设备在治疗小儿肾结石中的疗效。2010 年 2 月至 2020 年 8 月期间，86 例连续接受逆行性肾内手术（RIRS）的小儿患者入组本研究。应用排除标准后，回顾性分析了 79 例儿童的数据。根据激光设备功率分为 15W 组（组 15：=30）和 30W 组（组 30：=49）。比较两组的人口统计学特征、结石特征和临床疗效。两组间年龄、性别、身高、体重和结石特征相似。30W 组的平均手术时间更短。首次 RIRS 后结石清除率（SF）在组 15 为 66.7%，在组 30 为 83.3%。20mm 或更大肾结石的 SF 在组 15 为 0%，在组 30 为 62.5%。然而，两组的 SF 率无统计学差异。在小儿肾结石治疗中，与 15W 设备相比，30W Ho:YAG 激光设备可缩短手术时间，且尤其在大肾结石中，可通过更少的操作次数获得最终的结石清除状态。
