Hippocrates, who is generally considered a focal point for the start o
f western medical tradition, left behind a corpus of medical writings
that constituted the first recorded comprehensive health system. The p
ivotal point of the Hippocratic corpus was the Hippocratic Oath, which
outlined the duties of healers of his school, but demarcated lithotom
y as a practice that was off limits to his fellow physicians. Surgery
for bladder stone, urology in essence, was thus the first specifically
identified surgical subspecialty. (C) 1997, Elsevier Science Inc. All
