CT Abdomen and Pelvis Without IV Contrast There is no relevant literature to support the use of CT abdomen and pelvis without IV contrast (separate from CTU) in the evaluation of NMIBC. CT Abdomen With IV Contrast It has been suggested that abdominal CT can be obtained simultaneously with pelvic CT in a single scan, but its usefulness in detecting abdominal lymphadenopathy and metastases in patients with NMIBC may be limited due to the low risk of distant metastasis. In a study by Rajesh et al [30], a CT whole-body staging was performed in 201 patients with biopsy-proven bladder cancer to evaluate distant metastatic disease at the time of diagnosis. Of these patients, 6% had distant metastasis, with retroperitoneal lymph nodes being the most common site of metastasis. None of the patients with NMIBC had metastases detected by CT imaging. CT Abdomen Without and With IV Contrast There is no relevant literature to support the use of CT abdomen without and with IV contrast (separate from CTU) in the evaluation of NMIBC. 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 Abdomen Without IV Contrast There is no relevant literature to support the use of CT abdomen without IV contrast (separate from CTU) in the evaluation of NMIBC. CT Chest With IV Contrast Although chest CT is generally recommended for patients with MIBC [31,32], the necessity of chest CT in patients with NMIBC is not clearly established. The study by Juri et al [33] suggests that the risk of chest metastasis in patients with Ta or T1 NMIBC is low, and chest CT may not be necessary in these patients unless there is upstaging Pretreatment Staging of Urothelial Cancer 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 evaluation of NMIBC.
