Official title: Tumor Staging T of Bladder Tumours: Correlation of MRI and Anatomopathologic Analysis.
Run by University Hospital, Clermont-Ferrand · NCT05464576 · Data updated 2026-11-12
This study tests whether MRI can reliably indicate bladder tumor stage before TURB in adults with confirmed bladder tumors.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with a confirmed bladder tumor requiring TURB and able to read French.
✕Probably not a fit
Patients with contraindications to MRI or gadolinium contrast, or those not undergoing TURB, may not benefit.

What this trial studies
This single-center interventional study compares MRI findings to anatomopathology results from TURB in patients with newly diagnosed urinary bladder tumors. The goal is to see if MRI can accurately reflect tumor invasion level and potentially reduce reliance on invasive pathology for staging. Eligible participants are adults with bladder tumors confirmed by cystoscopy who are planned for TURB and can read French. MRI is performed with gadolinium contrast unless contraindicated, and results are compared to the gold-standard TURB pathology. The study builds on prior work suggesting MRI improvements may aid bladder cancer staging, aiming to improve diagnostic timing and patient management.
Why it matters
Potential benefit: If successful, MRI could improve preoperative staging accuracy and streamline patient care by informing treatment decisions earlier.
How similar studies have gone: Previous data suggest MRI can help assess bladder tumor invasion, but direct correlation with TURB pathology is still evolving and this study adds single-center validation.
