摘要

简介：980 nm波长二极管激光是新一代激光，用于复发性膀胱癌的激光消融比传统经尿道膀胱肿瘤切除术具有更低的并发症发生率和复发率。这是日本首次报道使用980纳米二极管激光消融治疗复发性非肌肉浸润性膀胱癌。病例介绍：一名73岁男性接受经尿道激光消融治疗复发性非肌肉侵袭性膀胱癌。激光照射采用LEONARDO DUAL（二极管激光器/980 nm波长）和400 μm BARE激光光纤。病理诊断为低级别尿路上皮癌，pTa。患者于术后第二天出院，无围手术期及术后并发症。结论：本病例提示经尿道激光消融治疗复发性非肌浸润性膀胱癌的潜力。

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. 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.
