title: Abdominal colic due to ureteric diverticulum with stone formation.
abstract: In a 15-year-old boy right lower abdominal colicky pain was caused by intermittent obstruction of the ureter by stones which had accumulated in a ureteric diverticulum. As was shown by repeated X-rays, each of these stones had moved to the ureter and back to the diverticulum. Ureteric diverticulum mostly remains asymptomatic in children: stone formation and obstruction of the ureter by the stones is one of the instances which may cause symptoms.
