Bipolar vs Monopolar Transurethral Resection of the Prostate (TURP)
Bipolar vs Monopolar Transurethral Resection of the Prostate (TURP)
This study will prospectively evaluate a new electrosurgical procedure (bipolar transurethral
 prostatectomy) in men with symptomatic benign prostatic hyperplasia.
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.
