Prostatic arterial embolisation for the treatment of lower urinary tract symptoms in men with benign prostatic hyperplasia

Review question:
What are the effects of a procedure that reduces blood flow to the prostate (called prostatic arterial embolization) in men with symptoms caused by an enlarged prostate?
Background:
An enlarged prostate may cause difficulty with urination such as a weak stream or the need to urinate often during the day or at night. This can be treated by medications or by different types of surgery. One main type of surgery is called transurethral resection of the prostate. This involves going inside the urethra through the penis and removing prostate tissue. Prostatic arterial embolization is another form of treatment that works by stopping blood flow to parts of the prostate. We did this study to compare how prostatic arterial embolization compares to transurethral resection of the prostate and other procedures used in men with an enlarged prostate.
