Benign Prostatic Hyperplasia, commonly known as an enlarged prostate, is a condition that affects a significant portion of the aging male population. By age 60, approximately half of all men will experience this condition, and that number rises to 80 to 90 percent for men over 70. When medications like alpha blockers or 5 alpha reductase inhibitors no longer provide adequate relief, or when their side effects become intolerable, it is time to explore procedural options.
For decades, Transurethral Resection of the Prostate (TURP) has been the standard surgical approach. However, Prostate Artery Embolization (PAE) has emerged as a highly effective, minimally invasive alternative. At Peak IR in Spokane Valley, we specialize in providing advanced interventional radiology treatments, and we want to help you understand how these two procedures compare.
Understanding BPH Treatment Options
When an enlarged prostate begins to compress the urethra, it causes lower urinary tract symptoms such as frequent urination, a weak stream, and the feeling that the bladder is never fully empty. Initially, these symptoms are often managed with daily medications. However, research indicates that over a five year period, about 10 percent of men on BPH medication will eventually require a procedural intervention.
When medications fail to control symptoms or cause unwanted side effects like dizziness or decreased libido, patients must weigh their options. The choice often comes down to traditional surgery versus minimally invasive procedures. Both aim to relieve the obstruction, but they do so in fundamentally different ways.
The Traditional Approach: TURP
Transurethral Resection of the Prostate, or TURP, is a surgical procedure designed to physically remove the prostate tissue that is blocking urine flow. During this operation, a surgeon inserts an instrument called a resectoscope through the urethra. Using an electrical loop, the surgeon cuts away the excess prostate tissue piece by piece.
Because TURP involves cutting tissue, it requires either general anesthesia or spinal anesthesia. Patients typically need to stay in the hospital for one to two days following the surgery. A urinary catheter is left in place for at least 24 to 48 hours to manage swelling and bleeding. While TURP is highly effective at improving urinary flow rates and reducing prostate volume, the recovery process can be significant. Patients are generally advised to avoid strenuous activities and sexual intercourse for four to six weeks.
The Minimally Invasive Alternative: PAE
Prostate Artery Embolization, or PAE, takes a completely different approach. Instead of cutting away tissue from the inside, PAE shrinks the prostate by reducing its blood supply. During this procedure, an interventional radiologist makes a tiny puncture in the wrist or groin to access the arterial system. A microcatheter is carefully navigated to the arteries supplying the prostate. Tiny particles, called microspheres, are then injected to block the blood flow. Deprived of its full blood supply, the enlarged prostate gradually shrinks over the following weeks and months, relieving the pressure on the urethra.
One of the most significant advantages of PAE is that it is performed with IV sedation as an outpatient procedure. Patients go home the same day, usually within a few hours of the treatment. The recovery is much faster than traditional surgery; most men can return to light activities and work within two to three days, and normal activities within a week.
Key Differences in Recovery and Side Effects
When comparing PAE and TURP, the differences in recovery and side effect profiles are substantial. Clinical trials, including a major randomized controlled trial comparing PAE and TURP, have shown that PAE is associated with significantly fewer complications.
The most notable difference lies in the preservation of sexual function. TURP has a high rate of sexual side effects, specifically retrograde ejaculation, which affects 65 to 80 percent of patients permanently. In contrast, multiple studies and meta analyses on sexual function preservation demonstrate that PAE has a statistically significant advantage in preserving normal ejaculatory function and erectile function.
Furthermore, because PAE does not involve cutting tissue, the risks of heavy bleeding, urethral strictures, and the need for prolonged catheterization are drastically reduced. While TURP may offer slightly greater improvements in maximum urinary flow rates, PAE provides excellent, long lasting symptom relief with a much gentler patient experience.
PAE vs TURP at a Glance
| Factor | PAE | TURP |
| Anesthesia | IV Sedation | General or spinal |
| Setting | Outpatient (go home same day) | Hospital stay (1 to 2 days) |
| Procedure Time | 1 to 2 hours | 60 to 90 minutes |
Return to Work | 2 to 3 days | 2 to 6 weeks |
| Return to Exercise | About 1 week | 4 to 6 weeks |
| Sexual Activity Resumption | About 1 week | 4 to 6 weeks |
| Retrograde Ejaculation Risk | Very low | 65 to 80 percent |
| Erectile Function | Preserved | Small risk of dysfunction |
| Symptom Improvement (IPSS) | 9 to 10 point reduction | 11 to 15 point reduction |
| Complication Rate | Lower (36 events vs 70 in RCT) | Higher |
| Incisions or Cuts | None | Yes |
Evaluating Your Options
Choosing the right treatment for an enlarged prostate is a personal decision that depends on your specific symptoms, prostate size, overall health, and lifestyle priorities. If you are looking for a treatment that avoids general anesthesia, does not require a hospital stay, and prioritizes the preservation of sexual function, Prostate Artery Embolization may be the ideal choice.
