Staging of bladder tumors by transurethral ultrasound tomography

The transurethral ultrasound tomography represents an important addition to the spectrum of diagnostic means for vesical tumors. On the basis of the comparisons between sonographic and histopathologic staging of 26 cystectomy specimens there was agreement in 20 cases. So far, limiting factors have proved to be the restricted penetration depth of the ultrasound probe used and the evaluation of the bladder outlet, which is possible to only a limited extent, even with retrograde transducers.
