Abstract :

Urinary tract stone disease or urolithiasis is a common problem worldwide. There are different modalities available for treatment of urinary tract stones disease which depends on stone composition, size, location, number and the patient factors. Knowledge of the composition of stones is a fundamental part of the preoperative patient evaluation, and this information influences treatment plans and prevention of recurrence. Currently stone composition can only be determined once it has been removed which is too late to impact treatment decisions. Recently, it has been shown that dual–energy CT (DECT) could be helpful in prediction of renal stone composition. The present study is being carried out to determine the accuracy of DECT in determining the composition of urinary tract calculi by correlating DECT prediction of stone composition with that of postoperative Fourier Transform Infrared Spectroscopy as the reference standard.
