title: Transurethral electrovaporization of the prostate versus transurethral prostatic resection: a comparison of postoperative hemorrhage.
abstract: OBJECTIVE
  To determine the acute and delayed hemorrhage rate of transurethral electrovaporization of the prostate (TEVP) versus standard transurethral resection of the prostate (TURP).
  
  
  METHODS
  A retrospective review of 524 consecutive patients who underwent TURP and 302 consecutive patients who underwent TEVP was conducted. The indications for both procedures were identical and based on history, physical examination, American Urological Association symptom score, and uroflowmetry. Parameters of evaluation included the incidence of both initial and delayed hemorrhages, the time until a delayed bleed occurred, blood transfusion rates, and the average length of stay in hospital after a bleed.
  
  
  RESULTS
  The overall hemorrhage rate for TURP and TEVP was 4.8% and 4.0%, respectively. In the TURP group, there was a 1.1% incidence of acute bleeds and 3.6% incidence of delayed bleeds. For the TEVP group, 0.3% had an acute hemorrhage, and 3.6% were readmitted for clot retention. The average length of time from original discharge to readmission was 12.9 days for the TURP group with a mean repeat stay of 5.7 days. For the TEVP group, the average interval to readmission was 15.4 days with a stay of 3.1 days.
  
  
  CONCLUSIONS
  The overall rate of hemorrhage for the TEVP group was slightly lower than for the TURP group due to fewer acute bleeds. However, the incidence of delayed bleeds and clot retention between the two was identical at 3.6%. Because of improved hemostasis intraoperatively with similar functional results in the long term as shown by other investigators, we foresee TEVP continuing as a viable alternative to TURP.
