title: Transurethral prostatectomy using Vista bipolar radiofrequency system: comparison with conventional transurethral resection of the prostate.
abstract: 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.
