目的比较经尿道绿激光汽化与经尿道电切治疗非肌层浸润性膀胱肿瘤的疗效及安全性。方法60例膀胱肿瘤中28例患者行经尿道绿激光汽化术(PVB组),32例行经尿道电切术(TURBt组),比较两组手术时间、保留导尿天数、术后并发症及肿瘤复发情况。结果两组平均手术时间、导尿管留置时间、尿道狭窄发生率均无明显差异(P>0.05);PVB组膀胱穿孔、术后膀胱冲洗例数及肿瘤复发情况低于电切组(P<0.05)。结论PVB治疗膀胱肿瘤具有术中出血少、并发症少等优点。
Objective To compare the efficacy and safety of transurethral green laser vaporization and transurethral resection of non-muscle invasive bladder tumor. Methods Twenty - six patients with bladder cancer undergoing transurethral vaporization of the urethral vaporization (PVB group) and 32 patients undergoing transurethral resection of the urethra (TURBt group) were enrolled in this study. The operative time, catheterization days, postoperative complications and tumor Recurrence. Results There was no significant difference in mean operative time, catheter indwelling time and the incidence of urethral stricture between the two groups (P> 0.05). The number of bladder perforation, the number of postoperative bladder irrigation and the recurrence of tumor in PVB group were lower than those in the resection group (P < 0.05). Conclusion PVB has the advantages of less intraoperative bleeding and less complications in the treatment of bladder cancer.
