Urine transported through the ureter from the kidney to the urinary bladder by peristaltic mechanism. Some of the problems related to urine transportation in ureter is back-flow, severe pain or in some rare cases, rupture of the ureter wall in an obstructed ureter. Ureter flow can get obstructed due to mineral deposits, from highly concentrated urine in the kidney and these deposits also known as kidney stones can then travel through the urinary tract. A number of numerical analyses have been conducted on the ureter to understand the flow mechanics as well as to understand the wall properties. But very few studies exist focusing on an obstructed ureter. To fully understand the effect of obstruction in a ureter, a comparative study of obstructed and unobstructed human ureter is required.
