The early and medium term results of this study into prostatic artery embolization or PAE are significant because they show PAE achieves comparable clinical results to that of the common surgical procedure "TURP", short for transurethral resection of the prostate, without the surgical risks, such as sexual dysfunction, urinary incontinence, retrograde ejaculation and blood loss, said study author Dr João Martins Pisco, chief radiologist at Hospital Pulido Valente and director of interventional radiology at St Louis Hospital, both in Lisbon.
However, certain urodynamic results (such as flow rate of the urinary stream), were not as good with PAE as with TURP.
The findings were presented at the Society of Interventional Radiology's 36th Annual Scientific Meeting
in Chicago this week.
Enlarged prostate, known as benign prostatic hyperplasia (BPH), is so common in men, it is often said that every man, if he
lives long enough, will have it.
BPH is not cancer, it is a condition where, as he
gets older, a man's prostate gets bigger.
Since the prostate surrounds the urethra, the tube that delivers urine from the bladder to the penis, there comes a point when its enlargement starts to squeeze the tube and impede flow.
This causes symptoms like weaker urine flow, a need to pass urine more frequently or more urgently, and incomplete bladder emptying.
Pisco, who is also a professor at the Faculty of Medical Sciences, New University of Lisbon, said "such symptoms can have significant negative impact in quality of life, leading many men to seek treatment," and we need new and inventive technologies like PAE to achieve better results with fewer side effects.
