Predictive Value of Current Imaging Modalities for the Detection of Urolithiasis During Pregnancy: a Multicenter, Longitudinal Study

Abstract

The rate of negative ureteroscopy was 14% among pregnant women undergoing intervention in our series. Of the group treated surgically after imaging with ultrasound alone, 23% had no ureteral stone, resulting in the lowest positive predictive value of the modalities used. Alternative imaging techniques, particularly low dose computerized tomography, offer improved diagnostic information that can optimize management and obviate unnecessary intervention.
