Abstract：Objective To investigate the efficacy and safety of mini-percutaneous nephrolithotomy(Mini-PCNL)and retrograde intrarenal surgery(RIRS)in the treatment of renal stones with 10-20 mm high hardness in children.Methods The clinical data of 62 children with renal calculi who underwent Mini-PCNL or RIRS at Beijing Friendship Hospital,Capital Medical University from June 2021 to June 2024 were retrospectively analyzed.The patients were divided into Mini-PCNL group(29 cases)and RIRS group(33 cases).The general data,intraoperative and postoperative data of the two groups were compared.Results There were no significant differences in general data between the two groups(all P＞0.05).The length of postoperative hospital stay and the decrease of hemoglobin in Mini-PCNL group were longer/greater than those in RIRS group[(4.7±1.7)d vs(2.9±1.5)d,6(4,10)g/L vs 2(0,4)g/L].The number of anesthesia and operation time in the Mini-PCNL group were less/shorter than those in the RIRS group[(1.9±0.3)times vs(2.8±0.4)times,(58±19)min vs(69±21)min](all P＜0.05).Conclusions Mini-PCNL and RIRS have good stone-free effect and safety in the treatment of renal stones with 10-20 mm high hardness in children.Although Mini-PCNL has longer hospital stay,it has the advantages of shorter operation time and fewer times of anesthesia.
