Transurethral resection specimens of the bladder: outcome of invasive urothelial cancer involving muscle bundles indeterminate between muscularis mucosae and muscularis propria.

摘要

OBJECTIVES: Thin muscle fibers on transurethral resection of the bladder (TURB) can represent either muscularis propria destroyed or splayed by urothelial carcinoma or muscularis mucosae, which can be hyperplastic. METHODS: The data from 94 patients with invasive bladder cancer seen at our institution (1986-2008) with a mean of 25.4 months of follow-up, who had had an uncertain pathologic diagnosis, were analyzed (72 men and 22 women, mean age 69.4 years). RESULTS: Subsequent restaging TURB or a definitive therapeutic procedure performed
