Please note that this variant describes initial imaging evaluation after the discovery, by imaging or otherwise, of asymptomatic hydronephrosis in a pregnant patient with unknown cause. The choice of initial imaging in this situation is dependent on clinical context and on the information available from the means of hydronephrosis discovery (eg, CT, MR, US). CT Abdomen and Pelvis With IV Contrast There is limited evidence to support the use of CT abdomen and pelvis with IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause. CT Abdomen and Pelvis Without and With IV Contrast There is limited evidence to support the use of CT abdomen and pelvis without and with IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause. Hydronephrosis on Prior Imaging-Unknown Cause CT Abdomen and Pelvis Without IV Contrast There is limited evidence to support the use of CT abdomen and pelvis without IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause. CT Abdomen With IV Contrast There is limited evidence to support the use of CT abdomen with IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause. CT Abdomen Without and With IV Contrast There is limited evidence to support the use of CT abdomen without and with IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause. CT Abdomen Without IV Contrast There is limited evidence to support the use of CT abdomen without IV contrast (separate from CTU) for initial imaging of pregnant patients with asymptomatic hydronephrosis with unknown cause.
