To determine diagnosis and treatment options with USG and CT in large size ureteral stones.

Ureteral stones are usually small and originate from kidney. Primary ureteral stone is very rare and is associated with an abnormality. The most important issue is to determine treatment options according to stone properties and patient's clinic in patients with urinary tract stones. Direct urinary system graph can detect ureteral stone but ultrasonography and computed tomography scans are more convenient to determine treatment options, number of stones, location, size, degree of obstruction, and differential diagnosis of calcification.
