“…Abdominal ultrasound is useful to assess tumor size, degree of bladder wall invasion, and abdominal metastasis. 259 Currently, CT urography and MRI are preferred for diagnosing and staging bladder tumors. In humans, the current opinion is that the extent of invasion of the bladder wall cannot be accurately assessed by transabdominal ultrasound.…”

“…Aside from TAUS, other approaches include transurethral US and endoluminal US, also known as intravesical US. Akdas et al [73] reported an overall accuracy of 97% in diagnosing and staging bladder tumors with transurethral US in 104 patients: 96% for stage Ta-T1 lesions, 100% for T2 lesions, 92% for T3 lesions, and 100% for T4 lesions. Endoluminal US uses a miniature, high-frequency transducer introduced by a rigid cystoscope for intravesical evaluation [74,75].…”

Muscle-invasive bladder cancer (MIBC) has a tendency toward urothelial multifocality and is at risk for local and distant spread, most commonly to the lymph nodes, bone, lung, liver, and peritoneum. Pretreatment staging of MIBC should include imaging of the urothelial upper tract for synchronous lesions; imaging of the chest, abdomen, and pelvis for metastases; and MRI pelvis for local staging. CT abdomen and pelvis without and with contrast (CT urogram) is recommended to assess the urothelium and abdominopelvic organs. Pelvic MRI can improve local bladder staging accuracy. Chest imaging is also recommended with chest radiograph usually being adequate. FDG-PET/CT may be appropriate to identify nodal and metastatic disease. Chest CT may be useful in high-risk patients and those with findings on chest radiograph. Nonurogram CT and MRI of the abdomen and pelvis are usually not appropriate, and neither is radiographic intravenous urography, Tc-99m whole body bone scan, nor bladder ultrasound for pretreatment staging of MIBC. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

In a prospective study, 71 patients with superficial transitional cell carcinoma of the bladder were given topical immunotherapy with bacillus Calmette-Guerin after transurethral resection and the impact of cystoscopy and bladder wash-out cytology in assessment of recurrent tumours was investigated. Sixteen recurrences were noted histopathologically during the follow-up and 15 of them were also diagnosed properly by wash-out cytology (sensitivity 93.8%). During the follow-up, 10 patients had positive cytology results without evidence of recurrent tumour and 6 of them had recurred cystoscopically in 3 months' time. However, the remaining 4 patients were still tumour-free cystoscopically after a follow-up of 6 months (specificity 92.7%, positive predictive value 78.9%). Although, some false-positive results may be obtained by urine cytology after topical immunotherapy, urine cytology seems to be a reasonable alternative to more invasive and expensive methods during the follow-up of bladder tumours.
