    Abstract:
    OBJECTIVE: To compare the outcomes of mini-percutaneous nephrolithotomy (m-PCNL) and retrograde intrarenal surgery (RIRS) in treating renal stones in preschool-aged children. MATERIALS AND METHODS: Forty-five patients treated with m-PCNL and 32 patients treated with RIRS for renal stones were compared retrospectively. The operative and postoperative outcomes of both groups were analyzed retrospectively. RESULTS: The mean age and gender were similar between the groups. The mean stone size was 19.30 ± 4.21 mm for the RIRS group and 21.06 ± 5.61 mm for the PCNL group (P = .720). The mean operative times, fluoroscopy times, and hospitalization times were statistically higher in the PCNL group. The stone-free rates (SFRs) after a single procedure were 84.4% in the PCNL group and 75% in the RIRS group (P = .036). After auxiliary procedures, the overall SFRs reached 91.1% for the PCNL group and 90.6% for the RIRS group (P = .081). No major complications were observed for both groups. Minor complication (Clavien 1-3) rates were 15.5% and 12.5% for the PCNL and RIRC group, respectively (P = .385). CONCLUSION: RIRS has some advantages over PCNL such as shorter hospitalization times, shorter fluoroscopy times, and shorter operative time in treating renal stones. However, PCNL achieves higher SFR after a single session.
