Detection of pelvicalyceal system stone by Using CT-KUB

Abstract

The study aimed to determine the accuracy of computed tomography and ultrasound in measuring of pelvicalyceal system stone. This study was explained from May 2017 to December 2017, in yastbshiron hospital random samples of 50 patient, 33 males (66%) and 17 females (34%), their age from 20 to 65 years, where chosen for CT-KUB and renal US. CT KUB was obtained for the stone length, width, computed tomography (CT) number, and measured by using computer. Renal ultrasound was obtained for stone length, width and measured by using computer. CT- KUB was done by using Toshiba (16slices) machine with slice thickness 8mm, collimation 0.8*16 mm, 120 KVP and 150 MAs. The result showed the male were more affected than female, and there is linear relationship between the stone length, width, CT number with age There was significant correlation between age of the patient and stone size (correlation significant 0.943) as well as between size and stone density (correlation significant 0.920). Ct number can characterize the stone type and CT-KUB has accuracy 100%, sensetvity 100% and specificity equal zero. CT-KUB has great value in detection of calculus more than renal ultrasound as it is accurate without magnification.
