To assess the efficacy and safety of transurethral prostatectomy using Vista system, between 2002 and 2004, patients with symptomatic BPH without suspected cancer were treated using the Vista device. The therapeutic effect was retrospective studied compared with patients who were received by TURP. Bipolar resection using the Vista device exhibits a statistically difference in maximum urinary flow rate, RUV, IPSS and QOL(P < .05) 3 and 6 months after operation, and no transurethral resection syndrome occurred. TURP also exhibits a statistically difference in maximum urinary flow rate, RUV, IPSS and QOL(P < .05), but TURS occurred in 2 patients. Compared with TURP, the Vista device shows a statistically less blood loss (P < .05), and longer operation time in prostate enlarged III(0)(P < .05). The Vista system seems to be effective and safe, and especially fit the patients who have a bigger prostate and high risk factors. It appears to be an effective treatment for BPH. Long-term results should be evaluated.
为评估使用Vista系统进行经尿道前列腺切除术的疗效和安全性，在2002年至2004年期间，对无疑似癌症的有症状良性前列腺增生患者使用Vista设备进行治疗。与接受经尿道前列腺电切术（TURP）的患者相比，对治疗效果进行了回顾性研究。使用Vista设备进行双极切除术在术后3个月和6个月时，最大尿流率、残余尿量（RUV）、国际前列腺症状评分（IPSS）和生活质量（QOL）方面显示出统计学差异（P < .05），且未发生经尿道切除综合征。TURP在最大尿流率、RUV、IPSS和QOL方面也显示出统计学差异（P < .05），但有2例患者发生了经尿道切除综合征（TURS）。与TURP相比，Vista设备显示出统计学上失血更少（P < .05），在前列腺Ⅲ度增生患者中手术时间更长（P < .05）。Vista系统似乎有效且安全，尤其适合前列腺较大且有高危因素的患者。它似乎是治疗良性前列腺增生的一种有效方法。应评估其长期效果。
