Quick answer: Prostate artery embolization (PAE) and transurethral resection of the prostate (TURP) can both improve lower urinary tract symptoms caused by benign prostatic hyperplasia (BPH). PAE treats the prostate’s blood supply through an image-guided catheter, while TURP removes obstructing prostate tissue through the urethra. The right choice depends on prostate anatomy and size, symptom severity, bladder function, medical history, treatment goals, and evaluation by qualified specialists.
Request a PAE consultation in Van Nuys or Irvine, California, or call (310) 929-0026.
PAE is a minimally invasive, image-guided procedure performed by an interventional radiologist. A small catheter is advanced through an artery, usually from the wrist or groin, to reach arteries supplying the prostate. Microscopic particles reduce blood flow to targeted prostate tissue, allowing the gland to shrink over time.
TURP is an endoscopic operation performed by a urologist. An instrument is passed through the urethra and used to remove prostate tissue that is obstructing urine flow. There is no external surgical incision, but the treatment acts directly inside the urinary channel.
Both procedures require a complete evaluation. Symptoms that resemble BPH can also result from bladder dysfunction, urethral narrowing, infection, medication effects, neurologic conditions, or prostate cancer. A treatment decision should not be based on prostate size or symptoms alone.
| Question | PAE | TURP |
|---|---|---|
| How is it performed? | Catheter-based embolization through an artery using X-ray guidance | Endoscopic removal of prostate tissue through the urethra |
| Who performs it? | An appropriately trained interventional radiologist | A urologic surgeon |
| General anesthesia | Often not required; the exact sedation plan varies | Anesthesia is generally required; the type varies |
| Hospital stay | Commonly performed as an outpatient procedure | May be outpatient or require an overnight stay, depending on the patient and setting |
| Urinary catheter | Not required for every patient, although some patients need one temporarily | Commonly used for a period after the procedure |
| Symptom response | Improvement develops as the prostate shrinks over weeks to months | Urinary-flow improvement may be noticed sooner because tissue is removed directly |
| Sexual side effects | Lower risk of ejaculatory change in many published series, but sexual side effects remain possible | Retrograde ejaculation is a recognized and relatively common consequence |
| Tissue specimen | No prostate tissue is removed for pathology | Removed tissue can be examined by pathology |
| Radiation and contrast | Uses fluoroscopy and typically iodinated contrast | Does not require arterial fluoroscopy |
| Repeat treatment | Symptoms can persist or recur, and additional treatment may be needed | Symptoms can also recur, and additional treatment may be needed |
This table is a general educational comparison. Individual techniques, anesthesia, catheter use, recovery, and outcomes vary.
PAE may be considered for appropriately evaluated patients with bothersome urinary symptoms attributed to BPH who want a nonsurgical, artery-based option. It may be especially relevant to some patients with a large prostate, medical conditions that increase surgical risk, bleeding related to the prostate, long-term catheter use, or a strong desire to reduce the likelihood of ejaculatory dysfunction. Suitability is determined individually and requires collaboration with urologic care when appropriate.
The Society of Interventional Radiology’s multisociety position statement describes PAE as a treatment option for appropriately selected men with BPH and highlights several patient groups that may benefit from consideration. The American Urological Association guideline also includes PAE among procedural options, with attention to clinician expertise and patient counseling.
TURP may be preferred when direct and prompt removal of obstructing tissue is important, when anatomy is favorable for a transurethral approach, when a tissue specimen is clinically important, or when a patient and urologist decide that its benefits best match the patient’s priorities. TURP has a long clinical history and remains an important reference treatment for bladder outlet obstruction caused by BPH.
PAE should not proceed simply because urinary symptoms and an enlarged prostate are present. Further evaluation may be needed when there is concern for prostate cancer, active urinary infection, significant kidney impairment, contrast allergy, severe arterial disease, a bleeding disorder, a cause of symptoms outside the prostate, or bladder dysfunction that may limit improvement. Some findings are relative rather than absolute limitations, so the decision must be individualized.
Possible PAE risks include bruising or bleeding at the access site, pelvic discomfort, urinary symptoms during recovery, urinary infection, temporary urinary retention, blood in the urine or semen, contrast reaction, kidney injury, unintended embolization, and the possibility of incomplete improvement or later retreatment. Radiation exposure and arterial anatomy are also relevant considerations.
Possible TURP risks include bleeding, infection, temporary urinary difficulty, urinary incontinence, urethral or bladder-neck scarring, fluid or electrolyte complications, erectile dysfunction, retrograde ejaculation, and the possibility of persistent symptoms or later retreatment. The likelihood and importance of each risk vary by technique and patient.
No procedure can guarantee preservation of erections, ejaculation, continence, or fertility. Ask the treating physicians to explain the risks that matter most to you.
After PAE, many patients return home the same day. Pelvic pressure, urinary frequency, burning, fatigue, or other temporary symptoms can occur during the first several days. Symptom improvement is usually progressive rather than immediate because the prostate shrinks over time.
After TURP, a urinary catheter is commonly used while the treated area heals. Blood in the urine, urgency, frequency, and activity restrictions may continue during recovery. Urinary flow may improve earlier, but healing time varies.
Follow the individualized medication, hydration, activity, catheter, and emergency instructions supplied by your clinical team.
Neither procedure is best for every patient. PAE may better match a preference for an artery-based outpatient approach and a lower likelihood of ejaculatory change. TURP may better match a need for direct tissue removal and faster flow improvement. Clinical evaluation and shared decision-making are essential.
PAE does not operate through the urethra and published evidence generally reports fewer ejaculatory problems than after TURP. However, preservation cannot be guaranteed and sexual or ejaculatory changes remain possible.
Large prostate size does not automatically exclude PAE, and some guidelines and expert statements identify large prostates as a setting in which PAE may be considered. Arterial anatomy, symptoms, bladder function, cancer evaluation, and overall health still matter.
Some patients with persistent or recurrent symptoms after a previous BPH treatment may be evaluated for PAE. Prior procedures, current anatomy, and the cause of ongoing symptoms must be reviewed before making a recommendation.
Coverage varies by insurer, plan, medical necessity criteria, and provider network. Socal Interventional accepts most PPO plans, Medicare, self-pay, and some IPA plans, but benefits and authorization must be verified for each patient.
Dr. Nathanael Sabbah evaluates patients for prostate artery embolization at Socal Interventional in Van Nuys and Irvine. A consultation is designed to determine whether symptoms are compatible with BPH, whether additional evaluation is needed, and whether PAE should be considered alongside urologic alternatives.
