Conditions
Outcome Measures
Primary Outcomes (1)
Concordance between US and core needle biopsy stage and final surgical specimen pathologic stage
The radiology-assessed tumor stage from the ultrasound (US) and the core needle biopsy-assessed tumor stage will be compared with the final pathologic tumor stage.
Baseline (after completion of bladder surgery)
Study Arms (1)
Observational
Patients undergo standard of care radical cystectomy and residual tissues collected undergo US core needle biopsy. Additionally, patients have their medical records reviewed on study.
Interventions
Eligibility Criteria

You may qualify if:
- Undergoing radical cystectomy for confirmed or suspected urothelial carcinoma of the bladder
- Prior abdominal imaging
You may not qualify if:
- History of partial cystectomy or complex bladder reconstruction or substitution (i.e. bladder augment or urothelial recurrence in a neobladder)
