About this study
Official title: Prostatic Artery Embolization (PAE) for Treatment of Signs and Symptoms of Benign Prostatic Hyperplasia (BPH)
This is an open-labeled, non-randomized feasibility study to evaluate the safety of prostate artery embolization (PAE) for the treatment of lower urinary tract symptoms attributed to benign prostatic hyperplasia (BPH).
Read the detailed description
This pilot study will be a single center, open labeled, non-randomized feasibility study to evaluate the initial safety of PAE for the treatment of symptomatic bladder outlet obstruction. 30 adult male subjects will be enrolled in this study. If eligible patients will undergo the prostate artery embolization procedure in the Interventional Radiology department. An angiogram of the prostate arteries will be done. Small beads called Bead Block microspheres will be injected into the prostate artery to slow blood flow to the prostate in the hope of providing relief with minimal side effects and complications, for lower urinary tract symptoms caused by BPH. After the procedure the patient will be followed at 4 weeks, 12 weeks, 6 months, and 12 months post procedure.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Reported Treatment-related Adverse Events (AE) as Assessed by NCI CTCAE Grading Scale .
The number of graded adverse events was recorded to evaluate safety. They were graded using the following scale at 1, 3, 6, and 12 months post procedure:
Mild (grade 1): the event causes discomfort without disruption of normal daily activities Moderate (grade 2): the event causes discomfort that affects normal daily activities Severe (grade 3): the event makes the patient unable to perform normal daily activities or significantly affects his/her clinical status Life-threatening (grade 4): the patient was at risk of death at the time of the event Fatal (grade 5): the event caused death.
Measured: 1 year
Secondary outcomes (4)
Change in International Prostate Symptom Score (IPSS)
Questionnaire- IPSS has 7 questions. Answer choices are as follows. The International Prostate Symptom Score (IPSS) can be utilized to measure the severity of lower urinary tract symptoms.
It is a validated, reproducible scoring system to assess disease severity and response to therapy.
The IPSS is made up of 7 questions related to voiding symptoms. Scores can range from 0-35 with 0 being the better outcome and 35 the worst outcome.
Question 1-6 0-Not at all
- Less than 1 time in 5
- Less than half the time
- About half the time
- More than half the time
- Almost always
Question 7 0-None 1-1 time 2-2 times 3-3 times 4-4 times 5-5 or more times
Measured: Baseline, 1, 3, 6, 12 months post procedure
Change in Quality of Life (QOL) Bother Score
The total score ranges from 0-6 with 0 being the best outcome and 6 being the worst outcome.
Questionnaire- answers choices are as follows:
0- Delighted
- Pleased
- Mostly Satisfied
- Mixed about equality satisfied and dissatisfied
- Mostly Dissatisfied
- Unhappy
- Terrible
Measured: Baseline, 1, 3, 6, 12 months post procedure
Change in Benign Prostatic Hyperplasia (BPH) Impact Index Score
The BPH Impact Index is to assess the impact of BPH symptoms on patient health and functioning. It is a self-administered questionnaire with 4 questions about urinary problems during the past month regarding physical discomfort, worry about health, how bothersome symptoms are, and whether the symptoms are interfering with doing usual activities.The BII is an evaluative index useful in measuring the magnitude of change in the impact of BPH-LUTS within a person over time.
Scores range from 0-13 with 0 being the best outcome and 13 being the worst.
Questionnaire- consists of 4 questions; answer choices are as follows Question 1: 0-none, 1-only a little, 2-some, 3-a lot Question 2: 0-none, 1-only a little, 2-some, 3-a lot Question 3: 0-not at all bothersome, 1- bothers me a little, 2-bothers me some, 3-bothers me a lot Question 4: 0-none of the time, 1- a little of the time, 2- some of the time, 3-most of the time, 4-all of the time
Measured: Baseline, 1, 3, 6, 12 months post procedure
Change in Peak Urine Flow (Qmax)
Peak Urine Flow (Qmax) from urodynamic assessments will be summarized comparing baseline to follow up measurements
Measured: Baseline, 1, 3, 6, and 12 months post procedure
