经尿道绿激光汽化切除与等离子电切治疗浅表性膀胱肿瘤的疗效比较

Comparision between Transurethra I Green Laser Vaporization and Bipolar Plasma Kinetic Resection for the Treatment of Superficial Bladder Tumors

目的探讨经尿道绿激光汽化切除术治疗浅表性膀胱肿瘤的安全性和疗效。方法将61例膀胱肿瘤患者随机分为两组,31例行经尿道绿激光汽化切除手术,30例行经尿道等离子电切手术;比较两组患者手术时间、闭孔神经反射发生例数、膀胱穿孔例数、术中出血量、术后膀胱冲洗时间、术后保留尿管时间、肿瘤复发等情况。结果两组患者平均手术时间、术后保留尿管时间、术后肿瘤复发率差异均无统计学意义(P>0.05),但绿激光治疗组发生闭孔神经反射例数、膀胱穿孔例数、术中出血量、术后膀胱冲洗时间明显少于电切治疗组(P<0.05)。结论经尿道绿激光汽化切除术治疗浅表性膀胱肿瘤,安全可靠,疗效确切,尤其适用于膀胱侧壁肿瘤。

Objective To evaluate the clinical efficacy and safety of green light photoselective laser vaporiza-tion for the treatment of superficial bladder tumor. Methods 61 patients with superficial bladder tumors ,proved by pathological biopsy,were treated with transurethraI green laser vaporization and bipolar plasma kinetic resec-tion randomly. The mean operative time,blood loss,bladder perforation,indwelling urethral catheter time and in-cidences of postoperative recurrence were compared between 2 groups. Results No significant difference of mean operative time,indwelling urethral catheter time and incidences of postoperative recurrence was found between the two groups(P>0. 05). The blood loss and incidences of postoperative recurrence were lower in PVBT group than in PKRBT group (P<0 . 05 ). Conclusions Greenlight photoselective laser vaporization of superficial blad-der tumor is proved with high security,quick recovery and low recurrence rate.
