Characterization of Urinary Tract Urolithiasis using Computed Tomography

Abstract

Kidney stone disease is one of the most common diseases of the urinary system, which ranks third in urology departments after urinary tract infection and prostate disease, and is the most prevalent by 10-15%. This spread has also increased in the last twenty years with a high rate, from the mid-1990s to the beginning of the second millennium. The study aimed to characterize of urinary system stones by using computed tomography for kidney, ureter and bladder (CT-KUB), and performed in National Ribat university Hospital on 100 patients, they were recommended to have CT-KUB, by computed tomography (Toshiba a (64 slices) machine with slice thickness 5 mm, collimation of 0.3*64 mm, 120 Kvp and 150– 250 mill ampere) for urinary system diseases. The results of this study showed that the most affected age group are those between (50-59) years, and that males are 57% more likely to have kidney stone disease than women by 43%. This study showed that, the frequency distribution of location of stone, were the mean frequent location was right pelvic kidney with (29%), LT Pelvic kidney stone and LT UPJ Stone with (18%). The most common site for stones is the right kidney. The repeated kidney stone scale was from (1-50) mm with a density of (200-600) HU, and its type was Calcium Oxalate and Uric Acid. This study found that the CT device has the full ability to detect and measure the stones and know its type and the main component of it, and that there is a direct relationship between the present of stones with the increase of age, and an inverse relationship between stone size and age.
