A child with a large bladder stone: A case report

Bladder stones account for approximately 5% of all urinary system stones and are prevalent among children living in poor or rural regions. The symptoms and findings in children with bladder stones are usually urgency, frequency, incontinence, dysuria, pyuria, difficulty voiding, and fever, small caliber of urinary stream, lower abdominal pain and urinary intermittency. Most bladder stones are composed of calcium oxalate, followed by calcium phosphate, and they are usually larger than 2.5 cm in diameter. We present a case of a larger-than 2.5-cm bladder stone in a child.
