To compare the outcomes of percutaneous nephrolithotomy (PCNL) in 2 age groups.
Fifty-one renal units (RU) of 45 patients were operated between January 2006 and December 2010. In all patients, PCNL was performed by pediatric nephroscope of 17F size through a 20F Amplatz sheath. Patients were examined in 2 groups (Group1: ≤5 years, Group 2: >5 years) and outcomes were compared accordingly.
The mean age was 5.95 ± 3.63 years and male-to-female ratio was 23/22. The mean stone burden, operative time, and postoperative hospital stay were 4.24 ± 2.03 cm(2), 94.30 ± 37.28 min, and 5.18 ± 2.97 days, respectively. In the postoperative period, 44 renal units (86.2%) were stone-free. Two age groups were similar regarding the postoperative hospital stay, gender distribution, stone location, stone composition, and complication rates. However, stone burden and number of access was less and stone-free rate was higher in younger age group.
The stone-free rate in preschool children is at least as good as older children without an increase in complication rates. The older children (>5 years) have a higher stone burden and need multiple accesses more frequently. The complications are mostly low grade and can be managed conservatively. Our results showed that PCNL in younger children as safe and effective as in the older children and age should not be considered as a limiting factor.
比较 2 个年龄组经皮肾镜取石术（PCNL）的结果。
2006 年 1 月至 2010 年 12 月，45 例患者共 51 个肾单位（RU）接受了手术。所有患者均采用 17F 大小的小儿肾镜通过 20F Amplatz 鞘进行 PCNL。患者分为 2 组（组 1：≤5 岁，组 2：>5 岁），并进行相应的比较。
平均年龄为 5.95 ± 3.63 岁，男女比例为 23/22。平均结石负荷、手术时间和术后住院时间分别为 4.24 ± 2.03cm²、94.30 ± 37.28min 和 5.18 ± 2.97 天。术后，44 个 RU（86.2%）结石清除。2 个年龄组在术后住院时间、性别分布、结石位置、结石成分和并发症发生率方面相似。然而，在年龄较小的组中，结石负荷和通道数量较少，结石清除率较高。
学龄前儿童的结石清除率与年龄较大的儿童一样好，且并发症发生率没有增加。年龄较大的儿童（>5 岁）结石负荷更高，需要多次通道。并发症大多为低级别，可保守治疗。我们的结果表明，PCNL 在年龄较小的儿童中与年龄较大的儿童一样安全有效，年龄不应作为限制因素。
