The accuracy of urinary ultrasound in the diagnosis of urinary stone disease in patients with acute flank pain: is it influenced by the time of ultrasound performance during the day or week?

Abstract

Our study showed no significant influence of US timing on its diagnostic accuracy. A larger randomized prospective series is necessary to evaluate the impact of different factors on "precision" and "accuracy" in US reporting and, hence, the diagnostic accuracy of urinary US in identifying urinary stone disease.
