Agreement between transurethral resection of bladder tumor and radical cystectomy pathology in patients with bladder cancer subtype histology: A retrospective cohort study.

Introduction And Objectives: Transurethral Resection of Bladder Tumor (TURBT) is a diagnostic staging procedure for bladder cancer (BC). Its pathologic interpretation may be limited by cautery artifact, lack of spatial orientation of tumor specimens, inter-pathologist variance in identifying subtypes, and sampling bias. Accurately identifying subtype histology (SH) on TURBT is critical for clinical decisions.
