Transurethral ultrasonography, CT scan, nuclear magnetic resonance (NMR) imaging and pathological control in staging and follow up of invasive bladder carcinoma.
Diagnostic accuracy in clinical staging of bladder cancer, using traditional methods, is still imperfect. Clinical and pathological staging do not always correlate. The accuracy of the new imaging techniques in the staging and in the follow-up of this kind of neoplasia, has yet to be assessed. Our study involved 7 patients with invasive bladder cancer who had undergone transurethral ultrasonography, CT scan, NMR and transurethral resection of the tumour. We have compared the clinical staging accuracy of the three imaging methods with the pathological reports. We conclude that transurethral ultrasonography is superior to the other methods, as far as local staging is concerned. In regional staging, NMR has shown very promising results and, in our preliminary opinion, may be more accurate than CT scan.
