Application of 16-Slice CT Urography in Upper Urinary Tract Obstructive Disorder

Objective To assess the application value of MSCTU(multi-slice computed tomography) in upper urinary obstructive disorders. Methods MSCTU was performed in 38 patients with upper urinary obstructive patients, and we reconstituted all abscissa axis images with 3D-reconstitution technology according obstructive level to select suitable delay scan time and got CTU post-processing images. Results Among 38 patients with upper urinary tract disorders, 13 cases were urolithiasis, 5 cases congenital urinary malformations, 8 cases upper urinary tract Obstruction caused by urinary neoplasm, 5 cases were stricture of ureter caused by inflammation or tuberculosis, and 7 cases by non-uretery derived tumor. The most early of delay scan time were 8 minutes and the most late were 2 hours. Conclusion MSCTU gets advantages such as high speed scan, excellent discrimination, and aplenty post-process technique, and is of great value in application of upper urinary obstructive.
