An enlarged prostate, medically known as benign prostatic hyperplasia (BPH), is a common condition in ageing men. Because of the enlargement of the prostate gland, pressure is created on the urethra causing obstruction of urine passage. Symptoms related to BPH are as follows: frequent urination, decreased urine flow, inability to initiate urination, urgency, nocturia, and incomplete emptying of the bladder.

An example of a procedure that can be used for the treatment of males who require a minimally invasive approach would be prostate artery embolisation. The difference between this procedure and the rest is that although other procedures use removal of prostate tissue, this procedure involves starving the prostate of its blood supply.

What Is Prostate Artery Embolisation? 

PAE is described as a minimally invasive treatment method for treating patients of BPH that affects the lower urinary tract. PAE involves the use of an interventional radiologist to insert a catheter in the body using imaging methods.

The process of performing PAE involves the insertion of tiny particles into the blood vessels that supply the prostate, resulting in reduced blood flow and shrinking of the gland.

PAE does not involve surgically removing prostate tissue. It may therefore be considered by selected patients who are looking for an alternative to more invasive procedures. However, suitability depends on the individual’s symptoms, prostate anatomy, medical history and evaluation by a qualified specialist.

How Does Prostate Artery Embolisation (PAE) Work?

The prostate receives blood through small arteries. In BPH, the enlarged prostate can place pressure on the urethra and contribute to urinary problems.

PAE uses image guidance to identify the arteries supplying the prostate. The interventional radiologist introduces a catheter through an artery, usually through the wrist or groin, and carefully guides it toward the prostate. Tiny embolic particles are then released into the prostate arteries to reduce blood supply.

With reduced blood flow, the prostate gradually shrinks. As the gland becomes smaller, pressure around the urethra may decrease, which can help improve urinary symptoms.

What Are the Types of Prostate Artery Embolisation? 

The approach used for PAE can vary according to a patient’s anatomy and the interventional radiologist’s technique. Common approaches include:

The appropriate approach is determined after imaging and clinical assessment.

Diagnosis and Tests for Enlarged Prostate 

Before considering PAE, doctors need to determine whether urinary symptoms are caused by BPH and assess the prostate and urinary system.

Common tests for enlarged prostate may include:

• Medical history and symptom assessment
• Physical examination
• Digital rectal examination
• Urinalysis
• PSA testing when clinically appropriate
• Ultrasound of the prostate or urinary system
• MRI in selected cases
• Assessment of prostate size and anatomy

A PSA test or additional investigations may be recommended to help rule out prostate cancer when appropriate. Johns Hopkins notes that pre-procedure assessment can include urinalysis, digital rectal examination, PSA testing in some cases, and prostate MRI or ultrasound.

How Is Prostate Artery Embolisation Done?

PAE is generally performed in an interventional radiology setting. The procedure typically involves several stages:

1. Pre-procedure assessment:

The doctor reviews your medical history, medications, symptoms and diagnostic results. Blood tests and imaging may be performed before treatment.

1. Local anaesthesia and sedation: 

The access area is numbed with local anaesthesia. Sedation may also be provided depending on the patient’s condition and the treating team’s recommendation.

1. Catheter placement: 

A thin catheter is inserted into an artery in the wrist or groin.

1. Imaging:

X-ray imaging and contrast dye help the interventional radiologist map the blood vessels supplying the prostate.

1. Embolisation: 

Tiny particles are injected through the catheter into the prostate arteries to reduce blood flow.

1. Completion and monitoring:

The catheter is removed, and the patient is monitored for a period before discharge, depending on the clinical situation.

Benefits of PAE

Potential benefits of PAE treatment include:

• Minimally invasive approach
• No surgical removal of prostate tissue
• Small catheter access rather than a large surgical incision
• Potential improvement in urinary symptoms
• Generally short initial recovery
• May be performed under local anaesthesia with or without sedation
• May be an option for selected patients who are unsuitable for or do not want traditional surgery

According to Johns Hopkins, PAE is a procedure considered to be minimally invasive in the treatment of LUTS caused by BPH and may pose a lesser possibility of adverse outcomes than other more invasive procedures.

However, benefits vary between patients, and PAE is not automatically suitable for every person with an enlarged prostate.

What Are the Risks and Disadvantages of PAE? 

Although PAE is minimally invasive, it is still a medical procedure and has potential risks.

Transient signs can include pain in the pelvis, increased need for urination, difficulty urinating, fatigue or fever. Complications include hematomas of the access site, presence of blood in urine, semen, or feces, bladder spasms, and infections.

Possible disadvantages include: 

• Symptoms may take time to improve fully.
• The procedure requires specialised imaging and an experienced interventional radiologist.
• Not every patient has suitable prostate artery anatomy.
• Urinary symptoms can temporarily become more noticeable after treatment.
• Some patients may eventually require additional treatment.
• PAE does not treat prostate cancer and appropriate evaluation is required before treatment.

Therefore, a detailed consultation is important before choosing PAE over medication or other Prostate Treatment options.

What Is the Recovery Time After PAE? 

PAE generally has a relatively short initial recovery period. Many patients can go home on the same day, although some may require overnight observation. Medanta notes that most patients can return to day-to-day activities within several days, while improvement in urinary symptoms can continue over weeks or months.

A general recovery pattern may look like this:

The exact recovery timeline varies. NG Vascular’s 2026 recovery guide describes symptom improvement beginning during the first few weeks, with more meaningful improvement commonly developing over one to three months.

How Soon Can I Return to Normal Activities After PAE? 

Many patients can return to light daily activities within a few days. However, strenuous exercise, heavy lifting and other activities may need to be restricted temporarily according to the treating doctor’s instructions.

Follow-up appointments are important because the prostate continues to respond to the reduced blood supply after the procedure.

PAE vs Other Prostate Treatments 

Treatment for BPH can include lifestyle measures, medicines, minimally invasive procedures and surgery. The choice depends on symptom severity, prostate size, overall health, previous treatments, anatomy and individual preferences.

A urologist or interventional radiologist can explain the expected benefits, limitations and risks of each option.

Conclusion

Prostate artery embolisation is a non-invasive option for some men having problems with urination due to prostate enlargement. Through the procedure, the prostate artery is blocked, thus making the prostate gland smaller through gradual reduction.

Familiarising oneself with the prostate enlargement symptoms, diagnostic methods, the steps in the procedure, the possible complications, and what to expect after the procedure allows one to have a better discussion about his/her condition with the doctor.

For people who are seeking prostate treatment in Hyderabad, consultations with a competent medical specialist are essential in determining if PAE, medicines, or any other prostate treatment would be the most suitable for them.

At Nanjappa, patient-centered health care knowledge and expertise are emphasised for the benefit of patients when it comes to choosing treatment options.
