Caliceal diverticular calculi are rather fixed and they are rare to be delivered spontaneously. We experienced a case of spontaneous passage of left ureteral multiple calculi from caliceal diverticular calculi. A 65-year-old female suffered from left back pain and was referred to our hospital. She was found to have left ureteral multiple calculi and left caliceal diverticular calculi. After a month observation, all ureteral calculi were delivered spontaneously. Multiple ureteral calculi from caliceal diverticular calculi could be delivered spontaneously and conservative management may be an option for the treatment.
