No scalpel: Minimally invasive breakthrough for men’s enlarged prostates improves symptoms
Date:3/29/2011

tic artery embolization after failing other medical treatments for at least six months, said Pisco. The men were followed for more than nine months (on average), and PAE was found to be technically successful in 98.5 percent of the patientswith 77 men showing "excellent" improvement, six men "slight improvement" (but needing no medications) and one experiencing no improvement (due to receiving an incomplete embolization), he added. Two hours after PAE, most men were passing urine less frequently. It was impossible to embolize both prostate arteries in the men showing "slight improvement" due to advanced atherosclerosis, said Pisco. According to Pisco, he used angiography (by pelvic magnetic resonance and computed tomography) to evaluate the possibility of embolizing prostatic blood vessels.

Prostatic artery embolization is performed by an interventional radiologist, a physician who is trained to perform this and other types of embolization and minimally invasive procedures. An interventional radiologist makes a tiny nick in the skin in the groin and inserts a microcatheter into the femoral artery. Using real-time imaging, the physician guides the catheter through the artery and then releases tiny particles, the size of grains of sand, into the prostatic arteries that supply blood to the tumor. These tiny particles block blood flow to the tumor, causing it to shrink. Following PAE treatment, most men experience no pain to light pain and leave the hospital four to eight hours after intervention. "There is no sexual dysfunction following prostatic artery embolization, and a quarter of our patients report that sexual function improved after the procedure," added Pisco.

BPH can be treated by TURP, a procedure in which a scope is inserted through the penis and the prostate is removed piece by piece, or surgery through an abdomen incision (prostatectomy). During surgery, a man generally undergoes general anaesthesia and needs to spend several days in a
