Difficulty in passing urine as you get older is commonly because of Benign prostatic hyperplasia (BPH) — also called prostate gland enlargement. Nearly half of men more than 60 years and 90% of those more than 80 years are affected by this condition. The prostate gland lies just under the urinary bladder; thus an enlarged prostate gland can block the flow of urine out of the bladder and cause difficulty in passing urine and other related symptoms.
During the PAE procedure, you’re given a mild sedative, but remain awake. The procedure begins with a tiny incision in your upper thigh or wrist to gain access to your arterial system. Using specialized X-ray equipment, the Interventional Radiologist guides a catheter (a small hollow tube) to the vessels that supply blood to your prostate. Once the IR reaches this location, embolic material (small particles about the size of a grain of sand) is injected through the catheter and into these blood vessels, decreasing blood flow to your prostate. The IR then repositions the catheter in order to treat the other side of your prostate. Depriving the prostate of oxygenated blood will cause it to shrink, thereby improving your urinary symptoms.
When the IR has completed embolization of the prostatic arteries, the catheter is gently removed. The entire PAE treatment can typically take anywhere from one to four hours to perform. You can go back home in a day’s time and resume normal activity. Rarely, you may require a catheter for a few days.
