Further study details as provided by Lawson Health Research Institute:

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

Secondary Outcome Measures:
  • 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 ]

Enrollment: 43
Study Start Date: May 2004
Study Completion Date: June 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 2
Bipolar Electrosurgical Unit
Procedure: Bipolar Transurethral Resection of the Prostate
Bipolar TURP
Other Name: Vista, Bipolar TURP
Active Comparator: 1
Monopolar Electrosurgical Unit
Procedure: Monopolar Transurethral Resection of the Prostate
Monopolar TURP
Other Name: Monopolar TURP

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.
