Initial experience of 980-nm diode laser treatment for recurrent non-muscle-invasive bladder cancer.

Introduction: Laser ablation using a 980-nm wavelength diode laser, which is a new-generation laser, for recurrent bladder cancer is known to have a lower incidence of complications and recurrence than conventional transurethral resection of bladder tumor surgery. This is the first study to report the use of 980-nm diode laser ablation for recurrent non-muscle-invasive bladder cancer in Japan.

Case Presentation: A 73-year-old man underwent transurethral laser ablation for the treatment of recurrent non-muscle-invasive bladder cancer.

Additional oncological benefit of photodynamic diagnosis with blue light cystoscopy in transurethral resection for primary non-muscle-invasive bladder cancer: A comparative study from experienced institutes.

Objectives: The objective of this work is to evaluate the additional oncological benefit of photodynamic diagnosis (PDD) using blue-light cystoscopy in transurethral resection (TURBT) for primary non-muscle-invasive bladder cancer (NMIBC) based on the International Bladder Cancer Group (IBCG)-defined progression and the subsequent pathological pathways.

Patients And Methods: We reviewed 1578 consecutive primary NMIBC patients undergoing white-light TURBT (WL-TURBT) or PDD-TURBT during 2006-2020. One-to-one propensity score-matching was performed using multivariable logistic regression to obtain balanced groups.
