PRIMARY OBJECTIVE
1\. To evaluate the symptomatic improvement in lower urinary tract symptoms after prostatic artery embolization (PAE)
SECONDARY OBJECTIVES
1. To evaluate objective measures of improved urinary obstruction after PAE: urine flow rate, prostate volume, and post-void residual
2. To measure effects of PAE on prostate specific antigen (PSA).
3. To evaluate if PAE reduces the prostate volume and simplifies radiation therapy
4. To evaluate the safety of PAE performed in this patient population
