title: A giant bladder struvite stone in an adolescent boy.
abstract: A 14-year-old adolescent boy with a history of recurrent lower urinary tract infection presented with a complaint of lower abdominal pain. Renal ultrasonography revealed bilateral hydronephrosis and X-ray film revealed a huge pelvic mass measuring 10 × 8 × 6 cm which filled the whole bladder. Open cystolithotomy was performed and magnesium ammonium phosphate (struvite) stone weighing 420 g was removed. Although a bladder stone is not rare, in the present report, the composition and the huge size of the stone determined in an adolescent patient is an interesting clinical entity. To the best of our knowledge, this is the largest struvite stone reported in an adolescent patient.
