Intra- and perivesical tumor growth in preoperative staging of bladder cancer: the role of transrectal ultrasonography and high resolution magnetic resonance imaging

Abstract

Bladder tumors were staged preoperatively before and/or after M-VEC poly-chemotherapy using transrectal ultrasonography and magnetic resonance imaging in 46 patients. The resultant findings were each compared with histomorphologic results. The sensitivity of both methods compared with pathohistology was 88%. Using this technique, the degree of tumor invasion of the bladder wall could be evaluated and the appropriate therapy selected. Further applications included the monitoring of transurethral resection determine its adequacy as a treatment modality.
