There is no single best procedure for BPH. The right choice depends on the size of your prostate, whether preserving sexual function matters to you, and how much downtime you can tolerate. The American Urological Association groups prostates into four size categories (small under 30 grams, average 30 to 80 grams, large 80 to 150 grams, and very large over 150 grams), and each category narrows the field considerably. What works well for a 40-gram prostate may not even be an option for one that’s 120 grams.
TURP, the traditional “roto-rooter” approach, remains the benchmark against which every newer procedure is measured. But it is no longer the automatic first choice. Laser enucleation, minimally invasive office procedures, and robotic waterjet technology all compete for different patient profiles. Here’s how they compare in the ways that actually matter to you: symptom relief, durability, sexual side effects, and recovery.
TURP: The Long-Standing Standard
Transurethral resection of the prostate (TURP) has decades of outcome data behind it and consistently delivers strong, durable symptom relief for average-sized prostates in the 30 to 80 gram range. In a large claims-based study, TURP had the lowest five-year retreatment rate of any procedure at 7.0%. That durability is its biggest selling point.
The trade-off is significant: retrograde ejaculation, where semen flows backward into the bladder during orgasm, occurs in roughly 50 to 70% of men after TURP. Erections are generally preserved, but the change in ejaculation is permanent for most. Recovery typically involves a hospital stay of about three days, a catheter for around two days, and several weeks before you feel back to normal. TURP requires general or spinal anesthesia in a hospital setting.
HoLEP: Size-Independent and Durable
Holmium laser enucleation of the prostate (HoLEP) is one of only two procedures the AUA considers truly “prostate size-independent,” meaning it works whether your prostate is 30 grams or 200 grams. That versatility makes it uniquely valuable for men with large or very large prostates who want an endoscopic (through-the-urethra) procedure rather than open surgery.
Symptom improvement after HoLEP matches TURP almost exactly. In a comparative study of older patients, symptom scores at four months were statistically equivalent between the two groups. Where HoLEP pulls ahead is recovery: hospital stays average one day compared to three for TURP, and catheter time drops from about 50 hours to 22 hours. You’re home faster and back to your routine sooner.
The downside mirrors TURP on the sexual side. Retrograde ejaculation rates after HoLEP run around 75 to 76%, actually slightly higher than TURP. Erectile function, however, remains comparable. The other limitation is availability. HoLEP demands specialized training and equipment, and not every urologist or hospital offers it. If preserving ejaculation is a priority, this is not the procedure for you.
UroLift: Preserving Sexual Function
The prostatic urethral lift (UroLift) works by placing small implants that hold the enlarged prostate tissue apart, like curtain tie-backs opening a window. It’s designed for prostates between 30 and 80 grams without an obstructing middle lobe.
Its standout advantage is sexual preservation. Clinical trials report zero cases of new erectile dysfunction and zero retrograde ejaculation. Men actually showed improvements in ejaculatory function scores after the procedure. UroLift can be performed in an office setting under local anesthesia, and most men return to normal activities within days rather than weeks.
The cost of those benefits is durability. The five-year surgical retreatment rate for UroLift sits around 11.6% in real-world data, roughly confirmed by the 13.6% rate seen in the original clinical trial. That’s nearly double the retreatment rate of TURP. Symptom improvement is also more modest. At three years, UroLift patients had somewhat less symptom relief than those treated with water vapor therapy. For men who prioritize sexual function and want to avoid general anesthesia, those trade-offs may be worthwhile. For men who want a one-and-done solution, they may not be.
Rezum: A Middle Ground
Water vapor thermal therapy (Rezum) uses targeted steam injections to destroy excess prostate tissue, which the body then gradually absorbs. Like UroLift, it covers prostates in the 30 to 80 gram range and can be performed in an office or outpatient setting.
Rezum occupies a middle ground between the minimally invasive options and traditional surgery. At three months, symptom improvement is nearly identical to UroLift (about 51% reduction in symptom scores). But Rezum pulls ahead over time: at both two and three years, it delivers statistically greater symptom relief. Its surgical retreatment rate of 4.4% is also substantially lower than UroLift’s 10.7%, putting it closer to TURP territory.
Sexual side effects are minimal but not zero. About 2.9% of men experienced absent ejaculation at three months, though this resolved entirely by one year. No new cases of erectile dysfunction were reported. The main inconvenience is that Rezum requires a catheter for several days afterward while the treated tissue breaks down, and full symptom improvement takes six to eight weeks as the body clears the damaged tissue. That delayed relief is something UroLift doesn’t share.
Options for Large Prostates Over 80 Grams
When the prostate exceeds 80 grams, many procedures drop off the table. TURP becomes less practical, and both UroLift and Rezum are not indicated above 80 grams. Three main options remain.
HoLEP (or the closely related thulium laser enucleation) handles large and very large prostates endoscopically. It avoids an external incision and delivers the shortest recovery of the options in this size range. Simple prostatectomy, whether open, laparoscopic, or robotic, physically removes the inner portion of the prostate through an incision. It’s the most invasive approach but extremely effective for very large glands, and AUA guidelines recommend it specifically for large to very large prostates depending on surgeon expertise.
Aquablation, a robotic waterjet procedure, is approved for prostates over 80 grams and uses real-time imaging to map and remove tissue. In comparative data, Aquablation patients tended to have somewhat smaller large prostates (averaging about 135 grams) compared to those selected for simple prostatectomy (averaging about 187 grams), suggesting surgeons may still prefer open or robotic removal for the biggest glands.
Comparing Sexual Side Effects
For many men, the risk to sexual function is the deciding factor. The differences across procedures are stark:
- UroLift: No reported retrograde ejaculation or new erectile dysfunction. The only procedure that actually improved ejaculatory function scores in trials.
- Rezum: About 3% temporary ejaculatory issues, resolving by one year. Zero new erectile dysfunction.
- TURP: 50 to 70% retrograde ejaculation rate. Erectile function generally preserved.
- HoLEP: 75 to 76% retrograde ejaculation rate. Erectile function generally preserved.
Retrograde ejaculation isn’t painful or dangerous, but it means dry orgasms and inability to father children naturally. For younger men or those for whom this matters, minimally invasive options offer a clear advantage.
Prostate Artery Embolization
Prostate artery embolization (PAE) is a non-surgical alternative performed by an interventional radiologist rather than a urologist. Tiny particles are injected into the blood vessels feeding the prostate, shrinking it over time. Johns Hopkins describes it as carrying lower risks of incontinence and sexual side effects compared to TURP. It’s generally positioned for men who are either ineligible for surgery or prefer to avoid it entirely. PAE is not yet part of the AUA’s core surgical recommendations, but it fills a niche for men with significant medical risks or strong preferences against operating room procedures.
Choosing Based on Your Priorities
If your prostate is under 80 grams and preserving ejaculation is your top priority, Rezum offers the best balance of durability and sexual preservation. Its retreatment rate is low, symptom relief is strong at three years, and sexual side effects are temporary and rare. UroLift is even gentler on sexual function but comes with roughly double the retreatment rate.
If you want maximum long-term durability and aren’t concerned about retrograde ejaculation, TURP and HoLEP both deliver. HoLEP has the edge in recovery time, and it’s the better choice if your prostate is large. For prostates over 80 grams, your realistic options narrow to HoLEP, simple prostatectomy, or Aquablation, and the decision often comes down to what your surgeon has the most experience performing. Surgeon expertise is a recurring theme in the AUA guidelines, and for technically demanding procedures like HoLEP or robotic prostatectomy, the skill of the person doing it matters as much as the technology itself.
