A history of urinary stone.

Urinary stone was well known to the ancient Greeks, as the reference to it in the Oath of Hippocrates shows. The oldest renal stone on record actually comes from an Egyptian mummy. For obvious reasons our forefathers were better acquainted with bladder stones than renal stones until the advent of radiography. Interesting aspects of the story are the gradual decline in the incidence of bladder stones and their apparent replacement by renal stones.
