Prostatic Artery Embolization: A Minimally Invasive Treatment for Benign Prostatic Hyperplasia

Image
  Prostatic Artery Embolization  What is Benign Prostatic Hyperplasia? Benign prostatic hyperplasia (BPH), also known as enlarged prostate, is a common condition that affects most men as they age. The prostate is a walnut-sized gland that sits below the bladder. As men get older, the prostate often enlarges and squeezes the urethra, the tube that carries urine from the bladder. This causes several bothersome lower urinary tract symptoms including frequent urination, difficulty starting or stopping the urine stream, feeling of incomplete bladder emptying, urgency, and dribbling. BPH requires treatment if it interferes with daily activities and causes urinary issues. Conventional Treatment Options for BPH Traditional treatment options for BPH include medication, surgery or a combination of both. Medications such as alpha blockers and 5-alpha reductase inhibitors work to relieve BPH symptoms by relaxing the prostate muscles and shrinking the enlarged gland. However, medications m...
