Subsequently, there have been hundreds of reports of foreign literature. Early literature on the disease named chaos, the current name of the majority of calyceal diverticulum (Cal-yceal Diverticulum) or Calyceal cyst (Calycealcyst). Although small calyceal diverticulum is not uncommon, but the larger are rare. So far there is no report in our country, so we come
