目的:探讨腔内经尿道铥激光切除联合并术后介入化疗治疗浸润性膀胱癌的疗效及安全性。方法:浸润性膀胱癌患者26例,其中多发肿瘤18例,单发肿瘤8例。肿瘤直径2.0～4.0cm,基底宽。行经尿道铥激光治疗。术后1周,行经股动脉致膀胱动脉介入化疗。结果:26例膀胱肿瘤均一次切除,切除范围距离肿瘤边缘正常黏膜1.0cm,深度达深肌层,平均手术时间35min。无明 Objective: To investigate the efficacy and safety of endoscopic transurethral resection combined with postoperative interventional chemotherapy for invasive bladder cancer. Methods: 26 cases of invasive bladder cancer, including 18 cases of multiple tumors, single tumor in 8 cases. Tumor diameter 2.0 ~ 4.0cm, basal width. Through the urethra 铥 laser treatment. One week after operation, the patients underwent transcatheter arterial chemotherapy through the femoral artery. Results: Twenty-six cases of bladder tumors were excised one time. The resection range was 1.0 cm from the normal mucosa at the margin of the tumor and reached the depth of the deep muscular layer with an average operation time of 35 min. Unknown
