Interventional radiology (IR) is a medical specialty that performs minimally invasive treatments using radiologic imaging for procedure guidance. Interventional radiologists at the IR Centers at Arizona Urology Specialists perform Prostatic Artery Embolization (PAE), a minimally invasive treatment that helps improve the symptoms of BPH/enlarged prostate without sexual side effects. Microscopic round microspheres (particles) are injected into the arteries that feed the prostate gland. Once inside the prostatic arteries, these beads block the blood flow to the regions of the prostate affected by BPH, reducing swelling in the gland that causes urinary symptoms.
