Usefulness of Transurethral Biopsy for Staging the Prostatic Urethra before Radical Cystectomy
Carcinoma, Transitional Cell
Neoplasms, Multiple Primary
Urinary Bladder Neoplasms
Prostatic involvement by urothelial carcinoma of the bladder was found in 37.1% of patients. Transurethral resection biopsy missed most tumors resulting from transmural invasion of the bladder primary lesion. Carcinoma in situ and invasive urothelial carcinoma arising from the prostatic urethra were detected in most cases. Transurethral resection biopsy of the prostatic urethra can complement staging and support clinical decision making with respect to neoadjuvant chemotherapy and planning for an orthotopic neobladder.
