Detailed Description
Background: Prostatic artery embolization (PAE) has recently been described as a promising alternative to surgery for treatment of lower urinary tract symptoms (LUTS) due to an enlarged, benign prostate. The treatment has not been implemented into international guidelines and has only been introduced to few patients in Norway.
Purpose: To compare PAE to the established surgical treatment for patient acceptance, morbidity, complications, and the functional outcomes. To compare length of stay, hospital costs and time for recovery.
Materials and Methods: 140 patients will be randomized to PAE or surgery. Patients should suffer from LUTS, be candidates for both treatments and willing to undergo both procedures. Before randomization computed tomography angiography of the pelvic arteries is done to select eligible patients. Magnetic resonance imaging of prostate rules out possible cancer. The PAE is done in the angio suite in the radiology department injection small particles into the prostate arteries. The surgery is done in the operation room in the urology department according to established procedures. All patients stay in the urology unit after the procedure. Clinical follow-up include clinical visit after 3 months, 1 and 5 years. Acute as well as long term complications will be recorded. The patients fill in the form of quality of life from urologic disease. Urodynamic examination will record functional outcome. Length of stay, procedure costs and recovery time will be recorded.
Importance of the study: Contribute to establishment of new treatment and help to select the right patients for the alternative treatments. Randomized study will give important information to the international community. It is possible to run this study in Norway because it is still in limited use.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Prostate operation
You will have a surgery to remove the prostate gland.
The surgery will be done during general anesthesia.
If your prostate gland is small the surgery will be done through a catheter into the penis.
If your prostate gland is large the surgery will be through an incision in your lower abdomen.
|
As described above.
|
Active Comparator: Prostate artery embolization
The embolization is done in the Department of Radiology.
There will be placement of a catheter into the artery in one of the groins during local anesthesia.
Through this catheter small particles will be injected into the arteries of the prostate gland.
When finished, the hole in the artery will be closed.
|
As described above.
|

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Quality of life due to urinary symptoms
Time Frame: 3 months
|
"Quality of life due to urinary symptoms" QoL = or <3 The scale used: Quality of Life Due to Urinary Symptoms.
Scale from 0 to 6, the worse is 6.
The patient question: If you were to spend the rest of Your life With Your urinary condition just the way it is now, how would you feel about that?
|
3 months
|
Number of patients with Prostate Artery Embolization that did not have prostate operation
Time Frame: 12 months
|
The investigators will record the number of patients that did not have prostate surgery after Prostate Artery Embolization.
After 3 months the patients will be offered operation when Quality of Life Due to Urinary Symptoms is 4-6 on the scale from 0-6 ie. the patients report unsatisfied (4), unhappy (5) or terrible (6).
|
12 months
|
Secondary Outcome Measures

|
Postoperative complications will be recorded according to the Clavien-Dindo classification system.
Complication will be recorded during hospital stay, at the follow-up after 3 months and at any intermediate points reported by the patients
|
