Patients with findings on chest radiographs and those thought to be at high risk should have chest CT, as is recommended in other guidelines [31,32]. Original research comparing the usefulness of chest radiographs with chest CT in this patient population is lacking. CT Chest Without and With IV Contrast There is no relevant literature to support the use of CT Chest without and with IV contrast in the pretreatment staging of UTUC. CT Chest Without IV Contrast All patients with UTUC need pulmonary evaluation [31]. Patients with findings on chest radiographs and those thought to be at high risk should have chest CT, as is recommended in other guidelines [31,32]. Original research comparing the usefulness of chest radiographs with chest CT in this patient population is lacking. CT chest with IV contrast is preferred over CT chest without IV contrast when evaluating for metastatic disease and lymphadenopathy. CT Pelvis With IV Contrast There is no relevant literature to support the use of CT pelvis with IV contrast (separate from CTU protocol) in the pretreatment staging of UTUC. Imaging of the entire abdomen and pelvis would be indicated for a comprehensive assessment of the entire urothelial system and evaluation for metastases. CTU and MRU are of greater usefulness because they allow for the comprehensive evaluation of the genitourinary tract, as well as the assessment of retroperitoneal and pelvic lymph nodes (see CTU and MRU sections). CT Pelvis Without and With IV Contrast There is no relevant literature to support the use of CT pelvis without and with IV contrast (separate from CTU protocol) in the pretreatment staging of UTUC. Imaging of the entire abdomen and pelvis would be indicated for a comprehensive assessment of the entire urothelial system and evaluation for metastases.
