Benign prostatic hyperplasia (BPH) is a common condition affecting the majority of men over 60 years of age. BPH incidence increases with age and often leads to lower urinary tract symptoms including frequency, urgency, and straining. In patients that do not respond to pharmacological therapy, options include transurethral procedures such as transurethral resection (TURP) or photovaporization, surgical prostatectomy, and prostate artery embolization (PAE).

The goal of PAE is to occlude arterial supply to the prostate by selective catheterization and subsequent embolization, most commonly with spherical tris-acryl gelatin microspheres. Over weeks to months, reduced blood flow leads to necrosis of prostatic adenomatous tissue, resulting in reduction of prostate size and decreased urethral impingement, eventually allowing for long-term resolution of symptoms in a majority of patients. Advantages of this technique compared with the standard surgical option, TURP, include faster recovery times, fewer side effects, and lower complication rates with near equal efficacy.

In our second interventional radiology video article, Dr. Raj Ayyagari at Yale New Haven Hospital performs a prostatic artery embolization on a patient with an enlarged prostate who also presented with hematuria. This procedure is appealing because it is less invasive and carries fewer risks than other treatment options.
