Abstract:
Objective To study the diagnostic value of 3 dimentional CT reconstruction in upper urinary tract obstructive diseases. Methods 37 patients with upper urinary tract obstructive diseases underwent thin slice helical CT scan and 3 dimentional reconstruction of the urinary tract as well as 3 dimentional CT angiography when needed. Results All the cases have been definitely diagnosed including ureteral carcinoma in 8, bladder carcinoma in 2, ureteral calculi in 9, benign ureteral stricture in 7, congenital malformation in 7 and pelvic tumor in 4.All the patients except those with pelvic tumors underwent surgical intervention and the diagnosis were confirmed.The operative findings were in concord with the helical CT results. Conclusions 3 dimentional CT reconstruction of the urinary tract can provide distinct urinary tract images and helps determining the site and the cause of the obstruction. Compared with other methods, the procedure has the advantages of high resolution, rapid imaging and low invasiveness. It might become the most valuable means of detecting upper urinary tract diseases.
