CT Abdomen and Pelvis With IV Contrast Although there is limited evidence to support the use of CT abdomen and pelvis with IV contrast (separate from CTU) for initial imaging of patients with asymptomatic bilateral hydronephrosis or asymptomatic hydronephrosis in a solitary kidney with unknown cause, it may be useful in this setting in some clinical situations. The addition of IV contrast is helpful in assessment for pelvic masses as a cause of bilateral hydronephrosis. More comprehensive evaluation can often be achieved with CT, MRU, or renal scintigraphy. 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 patients with asymptomatic bilateral hydronephrosis or asymptomatic hydronephrosis in a solitary kidney with unknown cause, and more comprehensive evaluation with CT, MRU, or renal scintigraphy is preferred. CT Abdomen and Pelvis Without IV Contrast Although there is limited evidence to support the use of CT abdomen and pelvis without IV contrast (separate from CTU) for initial imaging of patients with asymptomatic bilateral hydronephrosis or asymptomatic hydronephrosis in a solitary kidney with unknown cause, it may be useful in the setting of some clinical situations. A more comprehensive evaluation can often be achieved with CT, MRU, or renal scintigraphy. CT abdomen and pelvis without IV contrast is particularly useful when obstructive urolithiasis is a primary concern, although this etiology is less likely in the setting of bilateral hydronephrosis. 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 patients with asymptomatic bilateral hydronephrosis or asymptomatic hydronephrosis in a solitary kidney with unknown cause.
