Abstract

Objectives

To retrospectively evaluate the efficacy and safety of super-mini percutaneous nephrolithotomy (SMP) and retrograde intrarenal surgery (RIRS) for children with upper urinary tract calculus (1–2 cm).

Patients and methods

Children with upper urinary tract calculus (1–2 cm) who underwent the SMP or RIRS were enrolled in this study. Patients were divided into two groups: group SMP, 36 patients; and group RIRS, 25 patients. Patients were evaluated with KUB radiography or CT after 1 month. The collected data were analyzed.

Results

The mean stone size was 14.18 mm in group SMP, and 14.00 mm in group RIRS (p = 0.812). Group RIRS compared to group SMP showed longer operating time [76.3 vs 53.9 min (p = 0.002)], and postoperative hospital stay [4.2 vs 2.9 days (p = 0.011)]. The overall stone-free rate (SFR) was 94.4% for group SMP, and 60.0% for group RIRS in 1 month after operation (p = 0.001). The re-treatment rate was significantly higher in group RIRS compared to group SMP [20.0% vs 0.0% (p = 0.009)]. The complication rate was 5.6%, and 24.0% for groups SMP, and RIRS, respectively (p = 0.036).

Conclusions

SMP was more effective than RIRS to obtain a better SFR, less re-treatment rate, and complication rate in children with upper urinary tract calculus (1–2 cm).

超微型 PCNL 和输尿管软镜治疗儿童上尿路结石 (1-2 cm) 的比较

摘要

目标

回顾性评价超微型经皮肾镜取石术（SMP）和逆行肾内手术（RIRS）治疗儿童上尿路结石（1~2cm）的疗效和安全性。

患者和方法

接受 SMP 或 RIRS 治疗的患有上尿路结石 (1–2 cm) 的儿童被纳入本研究。患者分为两组：SMP组，36例；和 RIRS 组，25 名患者。1 个月后用 KUB 放射线照相术或 CT 对患者进行评估。对收集到的数据进行了分析。

结果

SMP 组的平均结石大小为 14.18 毫米，RIRS 组为 14.00 毫米 ( p  = 0.812)。与 SMP 组相比，RIRS 组手术时间更长 [76.3 vs 53.9 分钟 ( p  = 0.002)]，术后住院时间 [4.2 vs 2.9 天 ( p  = 0.011)]。术后 1 个月，SMP 组的总结石清除率 (SFR) 为 94.4%，RIRS 组为 60.0% ( p  = 0.001)。与 SMP 组相比，RIRS 组的再治疗率显着更高 [20.0% 对 0.0% ( p  = 0.009)]。SMP 组和 RIRS 组的并发症发生率分别为 5.6% 和 24.0% ( p  = 0.036)。

结论

SMP 比 RIRS 更有效地获得更好的 SFR，更少的再治疗率和上尿路结石（1-2 cm）儿童的并发症发生率。
