In the literature, there are few case reports regarding pediatric giant bladder stones, although they are more common in children living in low-income countries due to low socioeconomic status, a diet with low protein, animal milk (goat milk), and dehydration. Herein, we report a child with a giant bladder stone of 72 × 42 × 44 mm in dimension and 152 gm in weight successfully managed with open cystolithotomy. Early diagnosis and management of bladder stones in the pediatric age group are crucial to prevent subsequent complications including recurrent urinary tract infections, excessive antimicrobial use and dissemination of antimicrobial resistance, and consequent renal insufficiency.
