Urinary Incontinence or Obstruction
Prostate artery embolization (PAE)
Urinary incontinence caused by benign prostate hyperplasia (BPH)
In men, urinary incontinence can be caused by BPH—a condition where the prostate becomes enlarged but the enlargement is not caused by cancer. A new treatment option is available as an alternative to surgery, and with fewer complications than transurethral resection of the prostate: Prostate artery embolization (PAE). PAE may also be performed in men who are not candidates for traditional treatment methods, such as when BPH is smaller than 50 cc or larger than 80 cc.
PAE is performed by an interventional radiologist using image guidance to thread a catheter into the prostate artery on both sides of the enlarged gland. The artery is them embolized to block blood flow, causing the prostate to shrink.
The ureters are long, narrow tubes that carry urine from the kidneys to the bladder. Sometimes, ureters can become obstructed due to kidney stones, blood clots or kidney stones. A uretal stent is a thin, flexible tube threaded into the ureter by an interventional radiologist. During this procedure, a tube is placed through the skin on the patient’s back into the kidney to open the ureter and restore the flow of urine into the bladder. This is known as ureteral stenting.
