经尿道膀胱肿瘤电切术与等离子切除术的对比研究

目的：对比经尿道膀胱肿瘤电切术（TuRBT）与经尿道膀胱肿瘤等离子切除术（PKRBT）治疗膀胱肿瘤的效果。方法：将100例膀胱肿瘤患者随机分为两组：TURBT组55例，肿瘤直径（19±7）mm；T1 36例，T2 19例，G1 34例，G2 21例；其中膀胱侧壁肿瘤21例，多发肿瘤18例。PKRBT组45例，肿瘤直径（18±8）mm；T1 29例，T2 16例，G1 26例，G2 19例；膀胱侧壁肿瘤18例，多发肿瘤14例。统计患者术中失血量、手术时间、是否发生闭孔反射、术后2年内是否复发。结果：两组患者均一次手术完成，均未输血，无严重并发症发生。TURBT组手术时间（26．8±9．2）min，术中失血（47±25）ml，两年内复发率38．2％；PKRBT组手术时间（25．3±10．3）min，术中失血（41±23）ml，两年内复发率40％，两组比较无统计学意义。有膀胱侧壁肿瘤的患者术中发生闭孔神经反射率TURBT组为61．9％（13／21），PKRBT组为27．8%（5／18），两组比较有统计学意义。结论：PKRBT是一种安全、有效的手术方法，具有使用生理盐水冲洗，安全性高；低温切割，创面无焦伽；切割精确，止血效果良好，手术野清晰，闭孔神经反射发生率低等优点。

Curative Effectiveness of Transurethral Resection vs Plasmakinetic Resection for Bladder Tumors

Objective.. To compare the effect of transurethral resection of bladder tumor （TURBT） and plasmakinetic resection of bladder tumor （PKRBT）. Methods：One hundrend patients with bladder tumor were divided into two groups. There are 55 patients in the first Group, who received TURBT the other 45 patients in the second Group were received PKRBT. There were T1 36 cases, T2 19cases ;G1 34 cases, G2 21 cases; 21 parietal tumor cases, 18 multiple tumor cases in the first group, and The mean diameter of bladder tumor is （19±7） mm. There were T1 29cases, T2 16casesl G1 26cases, G2 19cases; 18 parietal tumor cases, 14 multiple tumor cases in the second group, and The mean diameter of bladder tumor is （18±8） mm. The blood loss, operation time, adductor reflex and recurrence were summurised. Results.. The tumor was resected at one stage in all cases. No patients needed blood transfusion or had serious complications. In group TURBT, the mean operating time was （26.8±9.2） min, blood lost （47±25） ml, the recurrence rate was 38.2% within two years after the operation. In group PKRBT, the mean operating time was （25.3±10.3） rain, blood lost （41±23） ml, the recurrence rate was 40% within two years after the operation. There was no significant difference between the two groups. The adductor reflex rate is 61.9% （13/21） in group TURBT, and 27.8% （5/18） in group PKRBT in the patients with parietal tumor. Conclu- sions..PKRBT is a effective and safe surgery for the treatment of bladder cancer. Washing with normal Saline, low cutting temperature and low adductor reflex were merits of PKRBT surgery compared with TURBT.
