Characterization of Renal Stone in Sudanese Population

Abstract

The general aim of this study was to evaluate the role of spiral computed tomography in the diagnosis of urinary tract stones. 100 patients were enrolled in the study multi detecter ct was performed. The result of the study showed that CT KUB has the ability to detect stones of the urinary tract accurately. And most of these stones appear in male (54.4%). Also the most affected age group is (40-49) with the number of stones that present in right side equal to those at the left side of the urinary tract. The renal pelvis showed the common site for stones 18.3%. Stones of the ureters are more likely to produce hydroureter and hydronephrosis. 50.8 % of stones are associated with hydronephrosis (27.9% mild, 57.4% moderate and 14.7% sever), and stones of the renal pelvis showed the most common site of stones to cause hydronephrosis. Furthermore, the most common site of ureteric stones was middle ureter 71.4%. Also 29.2 of stones are presented with obstructive changes and the upper ureter showed the most common sit for stones that cause obstruction. Spiral CT has largely replaced plain radiographs and IVP. CT for stones requires no contrast and no patient preparation, and the study is routinely completed in less than 90 seconds.
