title: Calculus formation on a retained Acucise wire.
abstract: We report the case of a patient who developed an obstructing calculus embedded at the ureteropelvic junction after treatment of ureteropelvic junction obstruction with the Acucise cutting balloon catheter. Within the length of the stone, we found a wire consistent with the cutting wire. To our knowledge, this is the first report of a fractured and retained cutting wire resulting in calculus formation.
