Abstract:
The study aimed to determine the accuracy of computed tomography kidney ureter bladder (CT-KUB) in measuring of urinary system stones.
This study was expanded from February 2013 to August 2013, in Yastabshiroon hospital Random samples of 50 patients, 33 males (66%) and 17 females (34%), their ages range from 20 to 65 years, were chosen for CT-KUB.
CT-KUB was obtained for the entire subject and the stones length, width, computed tomography (CT) number, and we were measured by using computer.
Scanning was done using Toshiba (16slices) machine with slice thickness 8mm, collimation of 0.8*16 mm, 120 kvp, and mAs 150 mill ampere.
The result showed, the male were more affect than female and there were linear relationship between the stone lengths, width, area, CT number with age.
CT number can characterize the stone type and CT-KUB has accuracy 100%, the sensitivity 100%, and the specificity equal zero.
There is significant correlation between age of the patient and stone size (correlation significant 0.934) as well as between the size and stone density (correlation significant 0.920).
CT-KUB has great value in detection of calculus as it is accurate without magnification.
