Background
Prostate artery embolization (PAE) has been utilized for years to successfully treat hematuria. Following a 2000 case report demonstrating incidental improvement in benign prostatic hypertrophy (BPH) symptoms after PAE for hematuria, additional studies followed showing promising results. Subsequently, many cases have followed and PAE has entered the treatment paradigm for BPH.

Educational Goals / Teaching Points
This exhibit aims to 1) provide a brief overview of the rationale and patient selection criteria for PAE in the treatment of BPH; review the arterial anatomy and technique of PAE; illustrate the above with a case-based format, including standard and complex examples.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes an overview of rationale and patient selection criteria for performing PAE, including a brief review of current data. We also review technical points of PAE, including the prostatic arterial anatomy (including variants); femoral versus radial access; overview of procedural technique; and potential complications.

Conclusion
PAE is a safe and efficacious treatment for BPH. PAE is an ideal treatment for: larger prostates (> 80–100g), poor surgical candidates, those with acute urinary retention, or those with refractory hematuria. PAE should be considered as part of the treatment paradigm for BPH along with other minimally invasive surgical therapies.
