title: Chronic perforation of the urinary bladder by self-inserted foreign body.
abstract: We report on a 14-year-old girl with pyelonephritis, secondary to a foreign body, in her urinary bladder. A self-inserted pencil led to stone formation and bladder perforation at two sites. Eighteen months after insertion, the pencil was removed by suprapubic cystotomy.
