The purpose of this study is to determine whether the transarterial supraselective embolization (TSE) is a technique as effective as transurethral resection of the prostate (TURP) for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH).

Inclusion Criteria:

• Diagnosis of benign prostatic hyperplasia with moderate or severe obstructive lower urinary tract symptoms
• Refractory to medical treatment for at least 6 months
• Qmax (maximum urinary flow) less than 10 mL/second

Exclusion Criteria:

• Patients not candidates for transurethral resection of the prostate (TURP)
• Advanced atherosclerosis and tortuosity of the iliac arteries
• No visualization of the prostatic artery CT angiography study
• Urethral stenosis, detrusor failure or neurogenic bladder
• Glomerular filtration < 30 mL/min
• Presence of malignant tumor
• History of allergy to iodinated contrast
• Patients with any other medical or social condition, deemed by the Investigator to be likely to interfere with a patient's ability to sign informed consent, cooperate and participate in the study, or interfere with the interpretation of the results
