Abstract:
We report an unusual case of a foreign body removed from the urinary bladder of an 11-year-old boy, which had mimicked a recurrent bladder stone. The diagnosis was suspected by ultrasound. As the clinical presentation appeared typical, no other examination was performed. Open surgery revealed that this foreign body was a surgical dressing forgotten during the first surgery eight years earlier. The absence of clinical evidence or infectious complications related to this foreign body over such a long period was surprising.
