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.
