The ureter is the tube that carries urine from the kidney to the bladder. It is located in the abdominal-pelvic visceral region, that is, the inner back part of the back (as a wall), sharing place with the pancreas, part of the liver and of course the spine. This tube has very interesting characteristics, since it contains the ability to control urinary flow, that is, the sphincter.
The ureter etymologically comes from the Greek “οὐρητήρ”, its inner body has the property of being mucous, in order to guarantee an effective transport of the liquid and the compounds that are formed in the kidneys. When this organ produces calculi, which are calcified elements, extra lubrication is needed for these to pass through the canal, they are not blocked and can damage the canal.
The basic composition of the ureter is of flexible muscles intertwined in layers of different fibers that allow control of the sphincter, the muscular layers cover the entire route from the kidney to the bladder.
Ureter duct failures are very vague, all mostly influenced by a change in the patient's anatomy or a complication in the kidneys, where the product that passes through the ureter comes from. A disease called "Retroperitoneal Fibrosis" creates tumors that, by accumulating size and shape, can deviate the ureter until pressing it against the tissue wall, blocking the passage. The kidney stones already mentioned above, being of considerable size, can cause rupture of the muscular tissue of the ureter.
