Implications of Guideline-based, Risk-stratified Restaging Transurethral Resection of High-grade Ta Urothelial Carcinoma on Bacillus Calmette-Guérin Therapy Outcomes

Guideline indications for restaging transurethral resection (reTUR) for high-grade (HG) Ta bladder tumors vary due to a paucity of data. To investigate guideline-based, risk-adapted approaches to reTUR for HG Ta lesions. An institutional review of HG Ta patients who received adequate bacillus Calmette-Guérin (BCG) from 2000 to 2019 was conducted. Guideline criteria for reTUR were used to stratify patients. Kaplan-Meier product limits estimated...
