A total of 27 patients with benign prostatic hyperplasia were treated by transurethral electrovaporization of the prostate (TUV-P). A roller bar electrode was used for 13 patients and a roller loop electrode for 14. Therapeutic efficacy and complications of TUV-P were compared with those of transurethral resection of the prostate (TUR-P) performed before TUV-P was started (24 patients). The improvements in subjective symptom scores and objective voiding parameters after 3 months were not significantly different between the TUV-P and TUR-P groups. Furthermore, the improvements were similar between TUV-P using the roller bar and the roller loop. No patients treated by TUV-P had TUR syndrome or received blood transfusion, while blood transfusion was performed in 4 patients treated by TUR-P. Postoperative duration of urethral catheterization and hospital stay was significantly shorter in the TUV-P group than in the TUR-P group. The operative time for TUV-P (roller bar) was 1.6 min per g. preoperative prostate volume, while that for TUV-P (roller loop) and TUR-P was 2.1 and 1.9 min/g, respectively. From our experience, TUV-P was as effective as TUR-P for relieving bladder outlet obstruction with fewer complications. Furthermore, the operative time could be shortened with a roller loop.
共有27例良性前列腺增生患者接受了经尿道前列腺电汽化术（TUV-P）治疗。其中13例患者使用滚轴电极，14例使用滚圈电极。将TUV-P的治疗效果和并发症与在开展TUV-P之前进行的经尿道前列腺切除术（TUR-P，24例患者）的效果和并发症进行比较。3个月后，TUV-P组和TUR-P组在主观症状评分和客观排尿参数方面的改善无显著差异。此外，使用滚轴电极和滚圈电极的TUV-P治疗效果相似。接受TUV-P治疗的患者无一发生TUR综合征或接受输血，而接受TUR-P治疗的4例患者进行了输血。TUV-P组术后尿道插管时间和住院时间明显短于TUR-P组。TUV-P（滚轴电极）的手术时间为每克术前前列腺体积1.6分钟，而TUV-P（滚圈电极）和TUR-P的手术时间分别为2.1分钟/克和1.9分钟/克。根据我们的经验，TUV-P在缓解膀胱出口梗阻方面与TUR-P同样有效，且并发症更少。此外，使用滚圈电极可缩短手术时间。
