title: [Transurethral vapor enucleation and resection of prostate with TURis button electrode].
abstract: OBJECTIVE
  To describe an efficient and effective method of using Olympus TURis button plasma vaporization electrode plus loop electrode for transurethral vapor enucleation and resection of prostate.
  
  
  METHODS
  Between July 2011 and October 2011, the investigators performed transurethral vapor enucleation and resection of prostate using Olympus TURis button plasma vaporization electrode plus loop electrode in 16 consecutive patients at our institution. The parameters of prostate weight, International Prostate Symptom Score (IPSS), quality of life (QOL), operative duration, blood loss volume, catheterization period, duration of hospitalization, perioperative complications and the weight of enucleated tissue were evaluated. IPSS and QOL were recorded during the follow-up.
  
  
  RESULTS
  No patient had significant blood loss or signs of transurethral resection syndrome. The mean patient age was 67.3 ± 8.1 years. Mean preoperative prostate weight was 49 ± 24 g (range: 19 - 91) and mean resected tissue weight 36 ± 16 g (range: 10 - 50). Serious complications were not observed. Operative duration was 116 ± 31 minutes, mean catheter time 4.9 ± 1.8 days and the duration of hospitalization was 16.6 ± 5.5 days. Transurethral vapor enucleation and resection of prostate induced significant, pronounced, immediate and lasting improvement in IPSS (15.6 ± 6.8 vs 6.7 ± 2.4, P < 0.01) and QOL (3.4 ± 1.4 vs 1.6 ± 0.6, P < 0.01).
  
  
  CONCLUSIONS
  Transurethral vapor enucleation and resection of prostate with Olympus TURis plasma button electrode is a safe, effective and thorough surgical method in the treatment of benign prostatic hyperplasia.
