Abstract

Objective: The aim of study was to study the chemical composition of renal stone in Sudanese population using computed tomography scan. Method: This is analytic study conducted in Khartoum state hospitals in the period from November 2018 to October 2019.The problem of the study was no similar study done in Sudanese populations. The study was done in 100 patients. The data was collected from computed tomography scan to the kidneys, ureters and urinary bladder. Classified and analyzed by statistical package for the social sciences application (SPSS). Results: The study found that most chemical composition of renal stone among Sudanese population was uric acid (0%), Cystine (26%) then Struvite (14%) and calcium (60%). The most effective age group with renal stone was (61-70) years old (36.7%) and same age group have a Struvite stone (28.3%). Furthermore, the most common age group with a cyctine renal stone were the cystine affect in the age between 50 years to 60 years old. The uric acid, Cystine, and calcium stone composition may be reliably predicted in vivo on the basis of dual-energy Computed tomography findings. In the future, a single dual-energy computed tomography examination may contribute to not only the identification but also the chemical characterization of stones in the urinary tract and it may add to the information available from nonenhanced conventional CT performed for evaluation of nephrolithiasis.
