Holmium laser enucleation of the prostate (HoLEP) is a surgical BPH treatment that's frequently called the gold standard for very large prostates — a reputation that, unlike some newer options in this space, is actually backed by two decades of randomized controlled trial data against TURP, the long-standing benchmark procedure. It works by using a holmium laser to fully separate (enucleate) the obstructing prostate tissue from its surrounding capsule, then removing that tissue through the urethra — functionally similar to an open or robotic simple prostatectomy, but done endoscopically with no external incision.

Why Size Doesn't Limit HoLEP the Way It Limits TURP
TURP removes tissue in small pieces, which becomes impractical and riskier (longer operative time, more bleeding) as prostate size increases — which is why very large prostates (traditionally 80-100mL or more) were historically sent to open surgery instead. HoLEP enucleates the entire obstructing tissue as larger pieces regardless of gland size, then morcellates it for removal, which is why it can treat prostates of virtually any size through the urethra, without an abdominal incision.
The Core RCT Evidence: HoLEP vs. TURP
A randomized trial assigned 61 men with prostates between 40-200 grams to HoLEP or TURP, with 2-year follow-up. Patients in the HoLEP group had shorter catheter times and hospital stays, and more prostate tissue was removed overall. At 6 months, HoLEP was urodynamically superior to TURP at relieving bladder outflow obstruction. By 24 months, symptom scores, quality-of-life scores, and peak flow rates were statistically similar between the two groups — but two patients in the TURP group needed re-operation for recurring obstruction, versus none in the HoLEP group [1]. A broader 2010 meta-analysis pooling 23 randomized trials and 2,245 patients comparing TURP against newer transurethral techniques, including HoLEP, found "statistically comparable efficacy and overall morbidity" for these modern alternatives versus TURP, concluding some of them "have the potential to replace TURP" as the default procedure [2].
HoLEP vs. Robotic Simple Prostatectomy for Very Large Prostates
For the very largest prostates, the other modern surgical option is robot-assisted simple prostatectomy (RASP) — essentially an open simple prostatectomy performed with robotic assistance. A 2026 systematic review and meta-analysis pooling 13 studies and nearly 2,000 patients compared the two head-to-head. HoLEP came out ahead on perioperative safety: a shorter operative time (about 32 minutes less on average), a lower transfusion rate, fewer serious (Clavien-Dindo grade III-IV) complications, and earlier catheter removal (almost 4 days sooner) [4]. RASP had a modestly better IPSS score improvement after surgery, but the two approaches showed no significant difference in quality of life, peak urinary flow rate, erectile function scores, PSA reduction, residual urine volume, blood loss, hospital stay, or incontinence rates [4]. The review's conclusion: HoLEP offers better perioperative safety with largely comparable functional results compared to robotic simple prostatectomy [4].
Sexual Function: What HoLEP Does and Doesn't Preserve
A large 2021 network meta-analysis pooling 48 papers, 33 randomized trials, and over 5,000 patients compared how different BPH surgeries affect erectile function specifically. Prostatic urethral lift (UroLift) ranked highest for preserving erectile function, reaching statistical significance at 24 months compared to standard TURP. For most other interventions, including HoLEP, there were no statistically significant differences in erectile function compared to TURP at any time point up to 60 months [3] — in plain terms, HoLEP doesn't appear to meaningfully help or hurt erectile function beyond what TURP does, in either direction, based on the trials available. One separate and important point worth being direct about: like TURP, HoLEP removes tissue from around the bladder neck, so retrograde ejaculation (where semen enters the bladder instead of exiting normally during orgasm) is common afterward — a tradeoff that newer, more tissue-sparing procedures like UroLift and Aquablation are specifically designed to reduce.
Whichever BPH procedure you're weighing, your IPSS score before and after surgery is the same validated measure these trials used to judge success — and it's something you can track yourself rather than relying on memory of how you felt.
A Newer Rival: Thulium Fiber Laser Enucleation (ThuFLEP)
A newer laser platform, thulium fiber laser enucleation (ThuFLEP), uses the same enucleation technique as HoLEP but a different laser wavelength. A 2026 systematic review and meta-analysis of 12 studies and nearly 1,250 patients found both techniques produced comparable functional improvements in symptom scores and flow rates, with ThuFLEP showing modest perioperative advantages — a shorter operative time, shorter catheterization, shorter hospital stay, and less bleeding — while overall complication rates were similar between the two [5]. In practice, this positions HoLEP as the established benchmark that a newer laser platform is being measured against, rather than being replaced by it; the choice between the two currently comes down more to equipment availability and surgeon training than to a clear efficacy advantage for either one.
What This Means If You're Weighing BPH Surgery Options
- •HoLEP has the longest track record of randomized trial evidence against TURP of any laser enucleation technique, with real reoperation-rate data, not just short-term symptom scores
- •It's a strong option specifically for large and very large prostates, where TURP becomes riskier and where it now has direct comparative data against robotic simple prostatectomy showing better perioperative safety
- •Expect retrograde ejaculation to be a likely outcome, similar to TURP — if preserving ejaculation is a priority and your prostate size allows it, ask your urologist whether UroLift or Aquablation are reasonable alternatives for your specific case
- •HoLEP has a genuinely steep surgeon learning curve compared to TURP — ask directly about your surgeon's case volume with this specific procedure, since outcomes are more operator-dependent than with more standardized techniques
- •Availability varies: HoLEP (and ThuFLEP) require specific laser equipment and specialized training, so it isn't offered at every urology practice the way TURP is

Frequently Asked Questions
Is HoLEP better than TURP?
For large prostates specifically, yes on several measures: a randomized trial found HoLEP had shorter catheter times and hospital stays, better urodynamic outcomes at 6 months, and zero reoperations at 2 years versus two in the TURP group [1]. For average-sized prostates, a broader meta-analysis found comparable efficacy and safety between HoLEP and TURP [2].
Is HoLEP good for very large prostates?
Yes — this is where it's most established. Unlike TURP, HoLEP isn't limited by prostate size. A 2026 meta-analysis comparing it directly to robotic simple prostatectomy (the other option for very large glands) found HoLEP had a shorter operative time, lower transfusion rate, and fewer serious complications, with largely comparable functional outcomes [4].
Does HoLEP cause erectile dysfunction?
The evidence doesn't show HoLEP meaningfully worsening erectile function compared to TURP. A network meta-analysis of over 5,000 patients across 33 randomized trials found no statistically significant difference in erectile function between HoLEP and TURP at any point up to 60 months [3].
Does HoLEP affect ejaculation?
Yes, commonly. Like TURP, HoLEP removes tissue around the bladder neck, which typically causes retrograde ejaculation. Procedures specifically designed to spare ejaculatory function, like UroLift or Aquablation, are worth asking about as alternatives if that's a priority and your prostate size and symptoms make you a candidate.
How does HoLEP compare to the newer thulium laser (ThuFLEP)?
They're largely comparable. A 2026 meta-analysis found similar symptom and flow-rate improvements between the two, with ThuFLEP showing modest advantages in operative time, catheterization duration, hospital stay, and bleeding, but similar overall complication rates [5]. The choice between them currently depends more on equipment and surgeon training than a clear efficacy difference.
The Bottom Line
HoLEP's reputation as a gold-standard BPH procedure, especially for large prostates, holds up against the evidence better than most newer options: two decades of randomized trial data against TURP, a real reoperation-rate advantage, and fresh 2026 data showing it outperforms robotic simple prostatectomy on perioperative safety while matching it on function. The honest tradeoffs are a steep surgeon learning curve and a likelihood of retrograde ejaculation similar to TURP. If ejaculation preservation matters more to you than it would to the average patient, that's worth a direct conversation with your urologist about whether a newer alternative fits your specific prostate size and symptoms.
