This is an open-labeled, non-randomized feasibility study to evaluate the safety of prostate artery embolization (PAE) for the treatment of lower urinary tract symptoms attributed to benign prostatic hyperplasia (BPH).
Benign Prostatic Hyperplasia (BPH)
Device: Prostate Artery Embolization
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Prostatic Artery Embolization (PAE) for Treatment of Signs and Symptoms of Benign Prostatic Hyperplasia (BPH)
Primary Outcome Measures:
- The Primary Objective is to evaluate the safety of prostate artery embolization (PAE) for the treatment of lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (BPH). [ Time Frame: 5 years ]
The number and the severity of adverse events will be recorded to evaluate safety. Events will be reported by subjects and the severity of events will be graded using the following scale:
Mild (grade 1): the event causes discomfort without disruption of normal daily activities Moderate (grade 2): the event causes discomfort that affects normal daily activities Severe (grade 3): the event makes the patient unable to perform normal daily activities or significantly affects his/her clinical status Life-threatening (grade 4): the patient was at risk of death at the time of the event Fatal (grade 5): the event caused death

Experimental: Prostate Artery Embolization
There is only one arm of this study where patients receive Prostate Artery Embolization
Device: Prostate Artery Embolization
Procedure completed in Interventional Radiology includes a pelvic/prostate angiogram and embolization with Embosphere microspheres to slow/block blood flow to the prostate.
This pilot study will be a single center, open labeled, non-randomized feasibility study to evaluate the initial safety of PAE for the treatment of symptomatic bladder outlet obstruction. 50 adult male subjects will be enrolled in this study. If eligible patients will undergo the prostate artery embolization procedure in the Interventional Radiology department. An angiogram of the prostate arteries will be done. Small beads called Embospheres will be injected into the prostate artery to slow blood flow to the prostate in the hope of providing relief with minimal side effects and complications, for lower urinary tract symptoms caused by BPH. After the procedure the patient will be followed at 4 weeks, 12 weeks, 6 months, 12 months post procedure and then annually for up to 4 years.
