Brief Summary:
This study will prospectively evaluate a new electrosurgical procedure (bipolar transurethral prostatectomy) in men with symptomatic benign prostatic hyperplasia.

Condition or disease Intervention/treatment Phase
BPH Benign Prostatic Hyperplasia Procedure: Bipolar Transurethral Resection of the Prostate Procedure: Monopolar Transurethral Resection of the Prostate Phase 4

Detailed Description:
The purpose of this study is to demonstrate that the Bipolar TURP using the Vista Controlled Tissue Resection System is safe and efficacious as a surgical treatment for men with symptomatic BPH, allowing a reduction in the post-operative hospitalization. It is expected that bipolar TURP will be safe and efficacious for the surgical treatment of BPH and will allow a < 24 hour post-operative hospital stay in > 50% of patients undergoing this procedure.

Primary Outcome Measures :
  1. Evaluation of efficacy will be determined by comparing pre and post-operative symptom scores. [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Pre and post-operative objective and subjective data for each treatment group will be assessed to determine safety and efficacy. Complications related to the surgical procedure will be noted by flexible cystoscopy at 6 months. [ Time Frame: 6 months ]
