The histologic classification of bladder tumors remains an important predictor of treatment response and patient outcome, with pure nonurothelial tumors associated with poorer outcome compared with pure urothelial carcinoma (UC). Little, however, is known about the significance of UC with divergent (mixed) histologic features at transurethral resection of bladder tumor (TURBT). This study examined the incidence, pathologic spectrum, and clinical significance of this phenomenon.
