There is no single “best” surgery for an enlarged prostate. The right procedure depends primarily on the size of your prostate, how severe your symptoms are, and whether preserving sexual function matters to you. That said, transurethral resection of the prostate (TURP) remains the gold standard, with an 86% success rate for symptom improvement. Newer options, from steam therapy to laser enucleation, work better for specific prostate sizes or patient priorities.
When Surgery Becomes Necessary
Most men with an enlarged prostate start with medications. Surgery enters the conversation when those stop working or when the condition causes complications that medication can’t fix. The American Urological Association recommends surgery for patients with kidney problems caused by the enlarged prostate, urinary retention that keeps coming back, recurring urinary tract infections, bladder stones, or blood in the urine. Surgery is also appropriate if you simply don’t want to take daily medication for the rest of your life.
If your symptoms are moderate but manageable, you have time to weigh your options. If you’re in the category of recurring retention or infections, the decision is more urgent and your urologist will likely recommend a more definitive procedure rather than a minimally invasive one.
TURP: The Gold Standard
TURP has been the benchmark prostate surgery for decades. A surgeon passes an instrument through the urethra and removes the obstructing prostate tissue in small chips, with no external incision. It works best for prostates under about 60 grams, which covers the majority of men who need surgery.
The results are strong. On a standardized symptom scoring scale, men typically drop from a preoperative score of about 17 (moderate-to-severe symptoms) down to 4 (mild symptoms) after the procedure. Men who start with more severe symptoms tend to see the most dramatic improvement, with an 87% chance of a meaningful reduction when the starting score is above 17. You’ll spend one to two nights in the hospital and can expect to return to normal activities within six to eight weeks.
The main drawback is its effect on ejaculation. Roughly 65 to 75% of men who undergo TURP experience retrograde ejaculation, where semen flows backward into the bladder during orgasm instead of out through the penis. This is painless and harmless but permanent, and it effectively means infertility. Erections and the sensation of orgasm are typically preserved.
HoLEP: Best for Larger Prostates
Holmium laser enucleation of the prostate (HoLEP) uses a laser to core out the obstructing tissue in larger pieces, which are then broken up and removed. It’s the preferred option when the prostate exceeds 60 grams, where TURP carries a higher risk of bleeding, incomplete removal, and a complication called TUR syndrome (a dangerous fluid imbalance).
HoLEP produces results comparable to TURP in symptom relief, but with less blood loss and a shorter hospital stay. Because it removes nearly all of the obstructing tissue, retreatment rates over the long term are very low. The tradeoff is similar to TURP when it comes to ejaculation: most men will experience retrograde ejaculation afterward. HoLEP also requires a surgeon with specialized training, so it’s not available at every hospital.
Robotic Simple Prostatectomy: For Very Large Prostates
When the prostate exceeds about 80 milliliters, robotic-assisted simple prostatectomy becomes an option. This is a more involved procedure where a surgeon uses a robotic system to remove the inner portion of the prostate through small abdominal incisions. It’s increasingly used for very large prostates where even HoLEP may be impractical. Recovery takes longer than TURP or HoLEP, but for men with substantially oversized prostates, it often provides the most complete tissue removal.
UroLift and Rezum: Preserving Sexual Function
These two minimally invasive options appeal to men who want symptom relief without the sexual side effects of traditional surgery. Neither one removes prostate tissue.
UroLift uses small implants to pin open the obstructing lobes of the prostate, like pulling back curtains. It’s a same-day procedure with a fast recovery and does not cause retrograde ejaculation. At five years, only about 1.75% of men needed retreatment in one long-term study. However, it works best for smaller prostates without a large middle lobe, and the degree of symptom improvement is generally more modest than TURP.
Rezum delivers steam (water vapor) into the prostate tissue through a needle, causing the excess tissue to gradually shrink over several weeks. Like UroLift, it preserves ejaculatory function and is done as an outpatient procedure. The retreatment rate at five years is higher than UroLift, at about 10%. Full symptom relief takes longer to kick in, often four to six weeks, because you’re waiting for the treated tissue to be reabsorbed by the body. You may need a catheter for a short period after the procedure.
Both UroLift and Rezum are best suited for men with moderate symptoms and smaller-to-medium prostates who prioritize maintaining normal ejaculation. They are not ideal for men with very large prostates or severe obstruction.
Prostatic Artery Embolization: A Non-Surgical Alternative
Prostatic artery embolization (PAE) is performed by an interventional radiologist rather than a urologist. Tiny particles are injected through a catheter in the wrist or groin to block blood flow to the prostate, causing it to shrink. It requires no general anesthesia and no instruments passing through the urethra.
PAE’s outcomes are more modest than traditional surgery. In a study of 88 patients who had PAE for urinary retention, 82% were able to have their catheter removed within a month, but long-term success dropped to 66% at follow-up. About 24% of patients eventually needed prostate surgery anyway. A three-year analysis showed a 60% probability of remaining catheter-free. PAE is typically considered when a patient can’t tolerate anesthesia or isn’t a candidate for other procedures.
How to Choose
The decision tree is more straightforward than it might seem. Your prostate size narrows the options quickly:
- Small to medium prostate (under 60 grams): TURP delivers the most reliable, durable results. UroLift or Rezum are reasonable if preserving ejaculation is a priority and you’re willing to accept somewhat less symptom improvement and the possibility of retreatment.
- Large prostate (60 to 80 grams): HoLEP is generally preferred over TURP because it handles larger tissue volumes more safely and effectively.
- Very large prostate (over 80 grams): Robotic simple prostatectomy or HoLEP, depending on surgeon expertise and availability.
Beyond size, your priorities matter. If you’re 55 and sexually active, the conversation about UroLift or Rezum is different than if you’re 75 and primarily concerned about being able to urinate without a catheter. If you’re on blood thinners or have heart conditions that make anesthesia risky, PAE or an in-office procedure may be safer. Ask your urologist specifically about their experience with the procedure they recommend. Outcomes for techniques like HoLEP and UroLift are highly dependent on the surgeon’s volume and training.
