Abstract

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. Laser irradiation was performed using LEONARDO DUAL (diode laser/980-nm wavelength) and a 400-μm BARE laser fiber. Pathological evaluation indicated low-grade urothelial carcinoma, pTa. The patient was discharged on the second postoperative day with no perioperative or postoperative complications.

Conclusion: This case suggests the potential of transurethral laser ablation for treating recurrent non-muscle-invasive bladder cancer.
