Prostatic Artery Embolisation (PAE) in Singapore
Minimally Invasive Treatment for Selected Men with an Enlarged Prostate
Prostatic artery embolisation (PAE) is a minimally invasive treatment for selected men with benign prostatic enlargement (BPE), also commonly referred to as benign prostatic hyperplasia (BPH).
An enlarged prostate can press against the urethra and interfere with the normal flow of urine. This can cause lower urinary tract symptoms such as difficulty starting urination, a weak or interrupted urinary stream, frequent urination and the need to urinate during the night.
During PAE, a specialist guides a thin catheter through the blood vessels to the arteries supplying the prostate. Small embolic particles are then delivered into selected prostatic arteries to reduce blood flow to the prostate.
Over time, reduced blood flow can cause the prostate tissue to shrink, which may help relieve urinary symptoms in appropriately selected patients.
At the Supreme Vascular and Interventional Clinic, vascular and interventional treatment is led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist.
With expertise spanning the brain and body, the Supreme Vascular and Interventional Clinic provides specialist-led vascular assessment, minimally invasive treatment and continuity of care under one roof.

What Is Prostatic Artery Embolisation?
Prostatic artery embolisation is a catheter-based treatment that reduces blood flow to selected arteries supplying an enlarged prostate.
The prostate is a gland located below the bladder and surrounds part of the urethra. As the prostate enlarges, it can place pressure on the urethra and contribute to difficulty passing urine.
During PAE, a specialist guides a catheter through the blood vessels towards the arteries supplying the prostate.
Small embolic particles are then delivered into selected prostatic arteries. These particles reduce blood flow to the targeted prostate tissue.
Over time, the reduced blood supply can cause the prostate to shrink, which may help improve urinary symptoms in selected patients.
PAE does not involve surgically removing the prostate.
What Is Benign Prostatic Enlargement?
Understanding BPE and BPH
Benign prostatic enlargement (BPE) is a non-cancerous enlargement of the prostate.
It is common as men get older and can contribute to lower urinary tract symptoms (LUTS).
Symptoms may include:
- Difficulty starting urination
- A weak or interrupted urinary stream
- Increased urinary frequency
- Urgency to urinate
- Waking frequently during the night to urinate
- Feeling that the bladder has not completely emptied
- Dribbling after urination
Having an enlarged prostate does not necessarily mean that treatment is required.
Treatment depends on the severity of symptoms, their impact on daily life, prostate characteristics and the individual's overall health. PAE is one of several treatment options that may be considered for selected men with symptomatic benign prostate enlargement.
How Does Prostatic Artery Embolisation Work?
Reducing Blood Flow to the Enlarged Prostate
Before PAE, detailed imaging is used to assess the prostate and map the arteries supplying it.
During the procedure, a small catheter is introduced into a blood vessel, usually through the wrist or groin. The catheter is carefully guided towards the arteries supplying the prostate.
Detailed X-ray imaging helps identify the relevant prostatic arteries. Small embolic particles are delivered into selected arteries.
The particles reduce blood flow to the targeted prostate tissue.
The catheter is removed after the planned treatment is completed.
Over the following weeks and months, reduced blood flow may cause the prostate to shrink. This can reduce pressure around the urethra and may improve urinary symptoms in appropriately selected patients.
Key Difference: PAE reduces blood flow to the prostate rather than surgically removing prostate tissue.
When Might PAE Be Recommended?
PAE may be considered for selected men with symptomatic benign prostate enlargement after appropriate assessment.
Your specialist will consider:
- The severity of your urinary symptoms
- Prostate size and anatomy
- The arteries supplying the prostate
- Your overall health
- Previous treatments
- Medications you are taking
- Whether you have other urinary or prostate conditions
- The potential benefits and risks of PAE
- Whether another treatment may be more appropriate
PAE is not suitable for everyone with an enlarged prostate.
A comprehensive assessment is important because urinary symptoms can have several possible causes and prostate cancer or other urological conditions may need to be excluded.
PAE vs Other Treatments for an Enlarged Prostate
Understanding Your Treatment Options
There are several approaches to managing symptomatic benign prostate enlargement.
| Treatment Approach | How It Works |
|---|---|
| Medical Management | Uses medications to improve urinary symptoms or reduce prostate-related obstruction |
| Prostatic Artery Embolisation (PAE) | Reduces blood flow to the prostate using catheter-delivered embolic particles |
| Transurethral Procedures | Uses instruments introduced through the urethra to remove or modify prostate tissue |
| Laser Prostate Procedures | Uses laser energy to remove or vaporise selected prostate tissue |
| Other Surgical Treatments | Surgically removes or modifies prostate tissue depending on the procedure |
The most appropriate treatment depends on prostate size and anatomy, urinary symptoms, overall health, previous treatment and individual preferences.
PAE provides a minimally invasive alternative for selected patients, but it is not necessarily the preferred treatment for every man with benign prostate enlargement.
Potential Benefits of PAE
A Minimally Invasive Approach to Prostate Treatment
For appropriately selected patients, PAE may offer several potential benefits.
Minimally Invasive Treatment
PAE is performed through a catheter inserted into the blood vessels rather than through an open surgical incision.
No Surgical Removal of the Prostate
PAE works by reducing blood flow to the prostate rather than surgically removing prostate tissue.
May Improve Urinary Symptoms
Reducing blood flow to the prostate can cause it to shrink over time and may improve lower urinary tract symptoms.
Can Be Considered for Larger Prostates
PAE may be considered in selected men with significantly enlarged prostates, depending on their anatomy and clinical circumstances.
Can Be an Alternative to Some Surgical Approaches
For selected patients, PAE may provide a minimally invasive alternative when appropriate after discussion of available treatment options.
It is important to remember: Every patient is different. The potential benefits of PAE depend on prostate characteristics, urinary symptoms, vascular anatomy and overall health.
What Are the Potential Risks and Limitations?
Understanding the Risks of PAE
Although PAE is minimally invasive, it is still a specialised vascular procedure and carries potential risks.
Potential risks may include:
- Temporary urinary symptoms
- Pelvic discomfort or pain
- Bleeding or bruising at the catheter access site
- Reaction to contrast dye
- Difficulty passing urine requiring temporary catheterisation
- Need for additional treatment
The risk of unintended embolisation is an important consideration because arteries supplying nearby organs may arise close to the prostatic arteries.
Detailed vascular imaging and careful catheter positioning are therefore important during PAE.
Your specialist will discuss the potential benefits, risks and alternative treatment options before recommending treatment.
Recovery After Prostatic Artery Embolisation
What Can You Expect After PAE?
Following PAE, you will be monitored while your recovery and catheter access site are assessed.
Some patients may experience temporary urinary symptoms, pelvic discomfort or other post-procedure symptoms during the early recovery period. In the first 24 to 48 hours, it is common to experience mild pelvic discomfort, fatigue, or temporary urinary symptoms such as increased urgency or a frequent urge to urinate as the prostate responds to the treatment. The prostate does not shrink immediately. Symptom improvement may develop progressively over the weeks and months following treatment.
PAE can typically take 1 to 2 hours to perform. Most patients are discharged on the same day to continue recovering at home, although a few may require an overnight stay for observation. Patients are generally able to resume light daily activities and return to work within a few days to a week.
Your specialist will provide personalised advice regarding:
- Medications
- Activity and exercise
- Catheter access-site care
- Urinary symptoms
- Follow-up appointments
- Further investigations if required
Long-term follow-up helps assess urinary symptoms and determine whether further treatment is required.

| 7 | Recovery & Follow-Up | Assess urinary symptoms and treatment response over time. |
PAE and Sexual Function
Discussing Sexual Health as Part of Treatment Planning
Concerns about sexual function are important when considering treatment for benign prostate enlargement.
Different prostate treatments can have different effects on sexual and urinary function. PAE does not involve surgically removing prostate tissue. However, individual outcomes can vary and PAE should not be presented as a treatment that guarantees preservation or improvement of sexual function.
Your specialist can discuss the potential effects of PAE and how they compare with other available treatment approaches as part of your individual treatment planning.
