Have you routinely sent out kidney stones for analysis of their composition?

The American Urological Association recently released its first guidelines for the medical management of kidney stone disease.

The guidelines, which contain 27 statements addressing evaluation, diet and pharmacologic therapies, and follow up, recommend that that a stone analysis be performed at least once if a stone is available because its composition can provide clues to certain underlying etiologies, such as a low urine pH in a patient with uric acid stones.

Renal & Urology News would like to know what urologists’ practice has been in this regard, so please address the following question. All responses are anonymous.
