title: Percutaneous endoscopic treatment for calyceal diverticular calculi.
abstract: A 29-year-old man complaining of gross hematuria was referred to our department. DIP demonstrated calyceal diverticular calculi of the left kidney. The patient requested ESWL, but the stone had not been discharged after two treatments. He then underwent PNL with dilation of the narrow neck of the calyceal diverticulum under fluoroscope. The neck of the diverticulum was dilated using an amplats dilator. Three months after the surgery, DIP demonstrated that the diverticulum was completely free from calculi and the size of the diverticulum was reduced. He was doing well 24 months after the operation. Calyceal diverticular calculi should be managed not only with ESWL and PNL but also with dilation of the narrow neck of the calyceal diverticulum.
