excretion Removal from the body of the waste products of metabolism.
Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
excretion any elimination from an organism of unwanted materials, for example, carbon dioxide and nitrogenous substances produced in METABOLISM. It is worth noting that excretory materials must be produced by the organism rather than just pass through it; thus faeces in mammals contain a mixture of excreta (e.g. bile pigments) and undigested gut contents. Compare SECRETION.

Patient discussion about excretion
Q. what is the best thing to do to eliminate or to let it be remove without surgery?I'm afraid but laser mayb ok If I can go for laser where can you suggest coz I'm jobless and can't afford to pay.Or is there some remedy that i can take to melt those stones inside my bladder then they can come out through my waste ?
A. Bladder stones, also called bladder calculi, often form when concentrated urine sits in your bladder. Bladder stones usually need to be removed. If the stone is small, your doctor may recommend that you drink an increased amount of water each day to help the stone pass. If the stone is large or doesn't pass on its own, your doctor may need to remove the stone. Bladder stones are usually removed during a procedure called a cystolitholapaxy. This is done by inserting a small tube with a camera at the end (cystoscope) through your urethra and into your bladder to view the stone. Your doctor uses a laser, ultrasound or mechanical device to break the stone into small pieces and then flushes the pieces from your bladder.
I am not familiar with the cost of such procedure.
