输尿管软镜与小通道经皮肾镜治疗儿童1～2厘米肾结石的对比研究OA北大核心

Objective To evaluate the safety and efficacy of flexible ureteroscopy(fURS)and mini-per-cutaneous nephrolithotomy(mini-PCNL)in the treatment of 1-2 cm renal stones in pediatric patients.Meth-ods This retrospective study analyzed the clinical data of pediatric patients treated for renal stones with fURS or mini-PCNL(F4.8 and F11)at Shanghai Children's Medical Center between October 2019 and October 2024.Patients were divided into the fURS group(n=26)and the mini-PCNL group(n=18)based on the surgical approach.Data on age,gender,stone size,location,proportion of lower calyx stones,cumulative operation time,hospital stay,hospital costs,and residual stones larger than 3 mm were compared between the groups.Results There were no significant differences between the fURS and mini-PCNL groups in terms of age[(64±44)months vs.(62±39)months],maximum stone diameter[(14±3)mm vs.(15±2)mm],stone density[(785±106)Hu vs.(813±101)Hu]or proportion of lower calyx stones(2/26 vs.4/18).However,the mini-PCNL group had significantly shorter cumulative hospital stay[(10±3)days vs.(6±1)days]and cumulative operation times[(95±28)min vs.(73±14)min](P＜0.05)There were no significant differences between the two groups in cumulative hospital costs[(34 583±4 548)yuan vs.(37 383±5 099)yuan]or stone-free rates at two months post-surgery(21/26 vs.16/18)(P＞0.05).Conclusions Mini-PCNL(F4.8,F11)is a safe and effective surgical option for treating 1-2 cm pediatric renal stones.Compared with fURS,it offers ad-vantages such as shorter operative and hospital stays,particularly for lower calyx stones.
