What is uretory?

It seems there might be a typo in your question, as "uretory" doesn't correspond to a commonly recognized term in English. If you're referring to "urethra," it is the tube that carries urine from the bladder to the outside of the body. Alternatively, if you meant "ureter," it refers to the tubes that transport urine from the kidneys to the bladder. Please clarify if you meant something else!
