[A case report of milk of calcium in a renal calyceal diverticulum].

A 24-year-old male with epigastralgia was admitted to our Hospital because a kidney, ureter, bladder X-ray (KUB) revealed a right renal stone. The upright view revealed a crescent-shaped density with horizontal fluid level in the right kidney. With the patient supine the density was round. On retrograde pyelography the stone-like shadow was not enhanced. Since there were no symptoms nor evidence of renal disease other than the density within the right kidney, no treatment for the kidney was given. The patient is being followed in the urological clinic.
