MSH: Pathological processes involving the URETERS.,MEDLINEPLUS: <p>Your kidneys form urine by filtering wastes and extra water from your blood. Your blood carries the waste to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder.</p><p>The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine downward and away from the kidneys. Small amounts of urine flow into the bladder from the ureters about every 10 to 15 seconds.</p><p>Problems with ureters may result from obstruction or injury. Also, if urine is allowed to stand still, or back up, you may develop a <a href='http://www.nlm.nih.gov/medlineplus/urinarytractinfections.html'>urinary tract infection</a>.</p><p>Doctors diagnose ureteral problems using different tests. These include urine tests, x-rays and examination of the ureter with a scope called a cystoscope. Treatment varies depending on the cause of the problem. It may include medicines and, in severe cases, surgery.
