PAE (Prostate Artery Embolization): a minimally invasive option—when the fit is right
PAE is increasingly discussed as an alternative to traditional prostate surgery. Some men arrive convinced it is the 'best' because it is minimally invasive. Others are unsure whether it is legitimate. The truth is more balanced: PAE can be an excellent option for selected men with BPH. It is not the right choice for everyone. The outcome depends heavily on candidacy and technique.
Quick navigation
What PAE is
PAE stands for Prostate Artery Embolization. In plain language: The prostate receives blood through small arteries. In PAE, a specialist navigates a thin catheter through blood vessels to the prostate arteries. Tiny particles are released to reduce blood flow to the prostate tissue—without cutting or shaving any tissue. Over time, the prostate will shrink and symptoms will improve. PAE does not remove tissue directly. It works through gradual shrinkage and reduction in obstruction.
Who is a good candidate (and who is not)
Often a good fit when:
You have moderate to severe BPH symptoms that affect quality of life. Medicines are not enough or not tolerated. You do NOT want to risk urinary or sexual complications of TURP/other surgeries. You want a minimally invasive approach (no cuts/no scars/no pain). Your anatomy supports treatable prostate artery patterns. You have medical risk factors where endoscopic surgery may be less desirable.
Might be less suitable when:
Your symptoms are primarily from bladder dysfunction rather than obstruction. There is a different disease that needs primary treatment. Your anatomy does not allow safe and effective embolization. You need very rapid decompression due to severe retention/complications. Important: PAE is not 'better' because it is less invasive. It is better only when it matches the clinical problem and anatomy.
What tests are usually needed before deciding
1) Symptom assessment
Weak stream, straining, incomplete emptying, nocturia and sleep impact, urgency/frequency, history of retention or catheter use, infections. Often a standardized symptom score is used.
2) Urine test
To rule out infection and hematuria-related concerns.
3) Ultrasound (including post-void residual)
This helps identify: residual urine after voiding, bladder wall changes, kidney impact, prostate size approximation.
4) PSA in context
PSA is interpreted with context (BPH/inflammation can elevate it). Decisions are individualized.
5) Cross-sectional imaging/angiographic planning
Imaging helps assess: prostate anatomy, arterial anatomy suitability, and procedural planning.
What happens on the day of the procedure
Exact details vary by center, but generally: You arrive for a planned day procedure or short stay. The access is typically through an artery in the wrist or groin. A catheter is guided to the prostate arteries under imaging guidance. Embolization is performed carefully on one or both sides. You are monitored afterward for pain control, urination comfort, and safety. You are back home that evening.
Expected benefits and timelines
Early period (first days to 2 weeks)
Urinary symptoms can fluctuate. Some men experience temporary irritation-like symptoms. Pain/discomfort varies and is managed with medicines.
Typical improvement window (weeks to a few months)
Many men experience: stronger stream, less straining, reduced nocturia, improved quality of life.
Longer-term stabilization
Because PAE works via shrinkage over time, improvement can continue gradually. Outcomes vary based on anatomy, baseline bladder function, severity and duration of obstruction, operator experience, adherence to follow-up.
Risks and side effects
Possible issues after PAE can include: temporary pelvic discomfort, urinary burning/frequency for a short period, transient worsening of symptoms before improvement, infection risk (managed with protocols), rare complications related to non-target embolization. However, these side effects and risks are significantly LESSER than other conventional surgeries. This is why this specialty (elective interventional radiology) are rising in popularity in the US and Europe—and MyDocsy is India's first company to offer elective interventional radiology procedures.
PAE vs TURP vs HoLEP/ThuLEP vs Rezum: how to think about it
PAE
Minimally invasive vascular approach. Improvement can be gradual. Candidacy depends on arterial anatomy.
Rezum
Minimally invasive transurethral therapy. Suitable for selected prostate patterns. Healing period can include temporary symptom flare.
TURP
Established endoscopic surgery. More immediate tissue removal and symptom relief. Standard option when anatomy/size suits.
HoLEP/ThuLEP
Laser enucleation approaches. Often chosen for durable relief in appropriate settings.
Recovery and follow-up
A good recovery plan includes: symptom tracking, follow-up appointments at defined intervals, review of urine tests/imaging if indicated, adjustment of medicines during the transition period. You should also have clarity on: when you can return to work, sexual activity guidance, what symptoms are normal healing vs warning signs.
FAQs
Talk to a doctor
If you are considering PAE, the most useful next step is a review to see if this procedure will work for you. You can share: ultrasound report, urine report, PSA levels, your symptom pattern. We will tell you plainly: whether PAE is appropriate to consider, what tests you still need, what outcomes are realistic, and which alternative procedure might fit better if PAE is not the best match.
