Photoselective Vaporization of the Prostate With the GreenLight XPS™ Laser System vs TURP for the Treatment of BPH
Photoselective Vaporization of the Prostate With the GreenLight XPS™ Laser System vs TURP for the Treatment of BPH
The study compares procedural and post procedural outcomes for photoselective vaporization of
 the prostate (PVP) and transurethral resection of the prostate (TURP) for the treatment of
 lower urinary tract symptoms due to benign prostatic enlargement causing bladder outlet
 obstruction. The study requires use of the CE marked GreenLight XPS™ Laser System (GreenLight
 XPS) or a CE marked monopolar or bipolar loop TURP system for the treatment of benign
 prostatic hyperplasia (BPH).
The study will compare procedural and post procedural outcomes for photoselective
 vaporization of the prostate (PVP) and transurethral resection of the prostate (TURP) for the
 treatment of lower urinary tract symptoms due to benign prostatic enlargement causing bladder
 outlet obstruction. The study requires use of the CE marked GreenLight XPS™ Laser System
 (GreenLight XPS) or a CE marked monopolar or bipolar loop TURP system for the treatment of
 benign prostatic hyperplasia (BPH). The purpose of the study is to demonstrate that PVP is
 not inferior to TURP.

 than 15ml/s (If uroflow testing documentation is available within 90 days prior to the
 informed consent date, and the sample is greater than or equal to 150ml, and the Qmax
 is less than 15ml/s it may be used for the inclusion/exclusion criteria)

 -  Subject has medical record documentation of a prostate volume of less than or equal to
 100g by transrectal ultrasound (TRUS) (If TRUS testing documentation is available from
 less than 180 days prior to the informed consent date and the prostate volume is less
 than or equal to 100g, it may be used for the inclusion/exclusion criteria)

 -  Subject is classified as American Society of Anesthesiologists (ASA) I, II or III

 -  Subject has a serum creatinine that is within the normal range for the laboratory at
 the study center (or documentation of clinical insignificance in the subject's medical
 record by the investigator if outside the normal range) and measured less than or
 equal to 30 days prior to the date of surgery.

 Exclusion criteria:

 -  Subject has a life expectancy of less than 2 years

 -  Subject is currently enrolled in, or plans to enroll in, any concurrent drug or device
 study unless preapproved by the sponsor

 -  Subject has an active infection (eg, urinary tract infection or prostatitis)

 -  Subject has a diagnosis of, or has received treatment for, chronic prostatitis or
 chronic pelvic pain syndrome (eg, non-bacterial chronic prostatitis)

 -  Subject has been diagnosed with a urethral stricture or bladder neck contracture
 within the 180 days prior to the informed consent date

 -  Subject has been diagnosed with 2 or more urethral strictures and/or bladder neck
 contractures within the 5 years prior to the informed consent date

 -  Subject has a diagnosis of lichen sclerosus

 -  Subject has a neurogenic bladder or other neurological disorder that would impact
 bladder function (eg, multiple sclerosis, Parkinson's disease, spinal cord injuries)

 -  Subject has a diagnosis of polyneuropathy (eg, diabetic)

 -  Subject has history of lower urinary tract surgery (eg, TURP, laser, urinary
 diversion, artificial urinary sphincter, penile prosthesis)

 -  Subject has diagnosis of stress urinary incontinence that requires treatment or daily
 pad/device use

 -  Subject has a history of intermittent self catheterization

 -  Subject has been catheterized or has a PVR >400mls in the 14 days prior to the

 -  Subject has a medical contraindication for undergoing either TURP or PVP surgery (eg,
 infection, coagulopathy or significant cardiac or other medical risk factors for
 surgery)

 -  Subject has a disorder of the coagulation cascade (eg, hemophilia) or disorders that
 affect platelet count or function (eg, Von Willebrand's disease) that would put the
 subject at risk for intraoperative or postoperative bleeding

 -  Subject is unable to discontinue anticoagulant and antiplatelet therapy preoperatively
 (3-5 days) except for low dose aspirin (eg, less than or equal to 100mg)

 -  Subject has had an acute myocardial infarction, open heart surgery or cardiac arrest
