We report a case of stone-containing pyelocaliceal diverticulum which was successfully managed by a percutaneous technique. Percutaneous management of pyelocaliceal diverticulum is discussed and four important points are stressed: 1) direct puncture is best, 2) the operation should be done carefully because a safety wire cannot be placed in most cases, 3) augmentation and stenting of the ostium are necessary and 4) shrinkage may be facilitated by the use of electrofulguration.
