经尿道电汽化术治疗浅表性膀胱癌

目的：探讨经尿道膀胱肿瘤电汽化术（TVBt）治疗浅表性膀胱移行细胞癌（TCC）的疗效。方法：对73例浅表性膀胱癌患者行TVBt术，其中12例合并良性前列腺增生症（BPH）者同时行经尿道前列腺电汽化术（TVP）。结果：72例膀胱肿瘤一次切除，1例多发性膀胱肿瘤分2次切除。平均手术时间TVBt为29min,TVBt TVB为78min，1例术中膀胱穿孔。全组无输血。术后平均留置尿管46h.73例均随访24个月，复发15例（21％）。结论：TVBt具有操作简便、止血效果好、汽化深度可靠、膀胱穿孔少及术后并发症低等优点。

Transurethral electrovaporization of superficial bladder cancer.

Objective To evaluate the safety, efficacy and morbidity of transurethral electrovaporization of superficial bladder tumor (TVBt). Methods TVBt was performed in seventy-three pat iens (mean age 66 years) with superficial bladder carcinoma,twelve of them trans urethral electrovaporization of the prostate (TVP) was carried out simultaneousl y for concomitant BPH. Results The tumor was resected in one-stage for 72 cases,in two-stage for multiple tumors in one patient. The mean operative time was 29 minutes in simple TVBt group, and 78 minutes in the group performing both TVBt and TVP. Intraoperative bladde r perforation occurred in 1 case, No patient need blood transfusion for bleeding . The mean duration of an indwelling urethral catheter was 46h. All patients wer e followed up for twenty-four months, and the recurrence rate was 21% within t wo years after the operation. Conclusions TVBt is a simp le, effective and safe surgery for the treatment of superficial bladder cancer.
