Characterization of Renal Stones by Computed Tomography and Ultrasound

Abstract

This study assessed the effectiveness of computed tomography and ultrasound in the diagnosis of renal stone and compared between two images modalities when they are applied for the same cases. It was conducted at radiology departments in Al-amal hospital _ Khartoum. This study was expanded from August 2011 up to December 2011. Random samples of 50 patients, 35males (70%)and 15 females (30%)their ages range from 15 to 72 years old with symptoms of renal stones were chosen, spiral CT and US were done to explain the suitable technique that demonstrate renal stones clearly. The most affected age group from 21-40 years old represent 56 %, most patients were affected in the both sides, with no history of renal stones in their families, kidneys were the most affected area, and Most patients suffer from kidney stones (36%) and ureters 6%). Ultrasound images have a role in the diagnosis of renal stones but CT scan is better and more sensitive. These results are established by account the number of appearances that showing in CT images and compared them with those appeared in ultrasound images It can be said that the two image modalities were performed together and used as essential techniques of renal stones, which help to obtain accurate diagnosis and demonstrate any changes that can affect urinar systems by stones.
