Abstract:
Objective To evaluate the diagnostic efficacy of the reformatted unenhanecded spiral CT of ureter for ureterolithiasis. Methods 39 patients were examined using nonenhenced spiral CT from the top of the kidneys to symphysis pubis in a single breath hold. The postprocessing method used in our studies was curved planar reformatting(CPR). Results Reformatted CT displayed clearly the entire course of ureter in all 39 cases . The diagnosis of ureterolithiasis was made on CPR views by definitive demonstration a calculus actually within the ureter, including the stone size, shape, location and the obstruction degree of ureter in 33 patients. The CPR views also demonstrated the ureter and the structures around clearly to aid greatly in differentiating the other 6 cases miscellaneous urinary tract conditions. Conclusion Our findings suggest that the reformatted nonenhanecded spiral CT of ureter has potential as an imaging tool for the ureterolithiasis and other urinary tract abnormalities.
