title: [The use of the PlasmaKinetic TUR system in the treatment of benign prostate hyperplasia: results of 1-year follow up].
abstract: OBJECTIVE
  The goal of this study was to evaluate the efficiency of the PlasmaKinetic (PK) system by comparing the preoperative and postoperative results in patients with benign prostate hyperplasia (BPH) treated in this hospital.
  
  
  METHODS
  From June 2004 to November 2006, the PK system was utilized for 46 cases of TUR-P in this Hospital. The patients International prostate symptom score (IPSS), QOL score, uroflowmetry, measurement of residual urine amount and ultrasonography were compared before and after the surgery (first month, third month and first year). In addition, the operation times, urethral catheterization times, preoperative and postoperative hemoglobin and serum sodium values of the patients were compared before and after the operations.
  
  
  RESULTS
  At 1 and 3 months and 1 year, the IPSS decreased from 28.2 +/- 7.4 to 6.1 +/- 5.9, 2.7 +/- 3.5 and 6.6 +/- 5.3, respectively. The QOL score, decreased from 5.4 +/- 1.0 to 0.9 +/- 1.2, 0.6 +/- 0.9 and 1.3 +/- 1.1, respectively. The maximum urinary flow increased from 3.7 +/- 4.0 ml/s to 19.5 +/- 9.6, 17.9 +/- 7.3 and 18.7 +/- 9.9 ml/s, respectively. The post void residual urine decreased from 104.8 +/- 83.6 ml to 19.4 +/- 25.0, 11.1 +/- 24.7 and 17.9 +/- 28.5 ml, respectively.
  
  
  CONCLUSIONS
  Acceptable outcomes with normal recovery from TUR-P were obtained using the PK system.
