Role of computed tomography with no contrast medium enhancement in predicting the outcome of extracorporeal shock wave lithotripsy for urinary calculi.


OBJECTIVE To evaluate the usefulness of urinary calculi attenuation values from non-contrast computed tomography (NCCT) in predicting the outcome of treatment by extracorporeal shock wave lithotripsy (ESWL). PATIENTS AND METHODS We evaluated 112 patients with solitary renal and upper ureteric calculi of 0.5-2 cm undergoing ESWL. All patients had NCCT at… (More)
