Several case reports showing that the long-term administration of magnesium trisilicate induced silica renal calculi. We report two cases of silicate renal calculi in children and the composition is purely silicon dioxide (100%) in both cases. The first child was a 7-year-old boy who presented with fever, vomiting, and loin pain for 2 months. His father and younger sister had undergone interventions for renal calculi. Intravenous urogram (IVU) revealed a left renal calculus of 2.2 × 1.8 cm which was treated by percutaneous nephrolithotomy (PCNL). The second case was an 8-year-old girl who's clinical and radiological evaluation lead to a diagnosis of left renal calculi which was treated by PCNL. In both cases the composition of the stone was 100% silicon dioxide. ER -
