Characterization of Urinary Tract Stones in Kassala State using Multi-detector Computed Tomography

Abstract

Non-contrastComputedtomographyis amethodforevaluatingthestonesofurinary system. Together with the measurement of the stone density and size, become an important way of assessing patients with suspectedstones. Theaim of this study was to evaluate the urinary system stones in patients who came with indication suspected to have urinary stone(s).The study sample was consisted of 100 patients with flank pain and clearly suspected for KUB stone or other pathological problem. A CT KUB was conductedatKassalastate. BytheCTKUBwefoundthemajority(91%)ofpatientsdeveloped(1-2)stones,the most stones located at pelvis (42%), lower calyces (21%) or mid ureter (10%) on either right site (43%) or left site (40%), since most of patients developed mild (28%) or moderate (36%) of Hydronephrosis and mostly (80%) negative Hydro- ureter, and The most common stone type (according to CT number ) cystine stones followed by struvite stones. For stone diameters, the sample found that the stone density was (386-1594)Hounsfield unit (HU) with mean 946.49±244.55, (3-33.5)withmean 10.33±6.73 X-size and (3-53.5) with mean14.28±9.48 Y-size.The results found that the stone site and its number are significantly associate with age (P-value < 0.05), while neither Hydronephrosis nor Hydroureter depend on stone site (P-value > 0.05).
