To evaluate the safety and efficacy of percutaneous mini-nephrolithotomy (mini-PCNL) in children with complex staghorn stones.Objectives: We analyzed prospectively data of 28 children undergoing pediatric mini-PCNL during a period of 18 months. Stone complexity was defined according to the validated Guy's stone score (GSS). Our patients were GSS III and IV. All PCNL procedures were performed in the prone position, under fluoroscopic guidance, and in the same standardized fashion with F12 and F17 mini-nephroscopes.Patients and Methods: Eleven children were boys (totalResults: n = 28). Mean age was 7.25 ± 3.27 (2–14) years. Mean stone burden was 36.89 ± 8.002 (30–60) mm. GSS was in 57% grade III and in 43% grade IV. The initial stone-free rate was 78%, which increased to 89% after few ancillary procedures. Seventeen percent of children had major complications (1 hydrothorax, 4 blood transfusions). On statistical analysis, stone clearance rates were found inversely dependent on stone complexity (GSS;p < 0.025). Stone burden, number of tracts, and procedure time were associated with stone complexity (p < 0.000). In turn, stone complexity (p < 0.015) and the number of tracts (p < 0.049) were significantly associated with complications. Mini-PCNL is effective and safe for treating complex renal stones in pediatric patients. Complication rates are acceptable and predictably stable on comparison with the literature.
