HoLEP (holmium laser enucleation of the prostate) is a minimally invasive surgery that uses a laser to remove enlarged prostate tissue blocking urine flow. It’s considered one of the most effective treatments for benign prostatic hyperplasia (BPH) and is the only laser-based prostate surgery that works regardless of how large the prostate has grown. The American Urological Association recommends it as a “prostate size-independent” option, meaning it can treat glands that are too big for other approaches.
How the Procedure Works
The surgery is performed through the urethra, so there are no external incisions. A surgeon inserts a scope and uses a holmium laser, which operates at a wavelength of 2,140 nanometers, to separate the overgrown prostate tissue from the outer capsule of the gland. The laser’s energy is absorbed by water in the tissue, and it only penetrates about half a millimeter deep. That shallow reach means it cuts precisely without causing heat damage to surrounding structures.
The surgeon works the laser tip side to side, peeling the inner prostate tissue away from the capsule much like separating the segments of an orange from its rind. Each lobe of the prostate is enucleated (separated as a whole piece) and pushed into the bladder. Once all the obstructing tissue is free, a morcellator, a device that simultaneously cuts and suctions, pulls the tissue fragments out of the bladder so they can be sent for pathology testing. This tissue removal is one reason HoLEP is preferred for very large prostates: it physically removes the obstruction rather than simply vaporizing or shaving it down.
Who Is a Candidate
HoLEP was originally favored for men with prostates larger than 80 cubic centimeters, where traditional surgery becomes more difficult. Over the past two decades, its use has expanded to smaller glands as well. Many centers now offer it as a first-line surgical option for BPH at any prostate size. Men with prostates over 150 cc, which would typically require open surgery, achieve similar outcomes to those with smaller glands.
Candidates are generally men whose urinary symptoms haven’t improved enough with medications, or who prefer a one-time surgical solution over daily pills. Men with active prostate cancer requiring treatment, or those with neurogenic bladder conditions, are typically not candidates.
What Results to Expect
The improvements in urinary symptoms after HoLEP are significant and durable. In a large study tracking over 1,200 patients for a year, symptom scores dropped from the severe range (around 23 out of 35 on the International Prostate Symptom Score) to about 5 or 6, which falls in the mild category. Peak urinary flow rate, a measure of how strongly you can urinate, more than doubled on average, going from roughly 8 milliliters per second before surgery to nearly 22 milliliters per second at 12 months. Quality of life scores and post-void residual (the amount of urine left in the bladder after urinating) also improved substantially.
These gains hold up well over time. Because HoLEP removes the obstructing tissue entirely rather than trimming it, the retreatment rate is very low compared to procedures that leave more tissue behind.
How HoLEP Compares to TURP
TURP (transurethral resection of the prostate) has long been the standard surgical treatment for BPH. It works by shaving away prostate tissue in small chips using an electrified loop. HoLEP removes the tissue in larger pieces using the laser, which translates into meaningful differences in recovery.
In a head-to-head comparison, HoLEP patients had their catheters removed after a median of 22 hours compared to 50 hours for TURP. Hospital stays were shorter too: one day versus three days. Most HoLEP patients go home the same day or the following morning. TURP also becomes riskier with larger prostates because the surgery takes longer and bleeding is harder to control, while HoLEP handles large glands without those limitations.
Recovery After Surgery
Most people spend a few hours in a recovery room and go home the same day. A catheter is placed during surgery and typically removed the next day unless there’s unusual bleeding, which is rare. You can expect some blood in your urine and urinary urgency for the first few weeks as the surgical site heals.
Recovery is faster than open prostate surgery or TURP, but you’ll still need to take it easy for a period afterward. Your surgeon will give you specific guidance on when to resume lifting heavy objects, exercising, and sexual activity. Most men notice a clear improvement in their urinary stream within the first few weeks, though symptoms like urgency and frequency can take a few months to fully settle.
Risks and Side Effects
The most common long-term side effect is retrograde ejaculation, where semen flows backward into the bladder during orgasm instead of exiting through the penis. This affects roughly 65% of men after HoLEP. It’s not painful or harmful, but it does mean little or no fluid comes out during climax, which matters for fertility and can feel different. This is a side effect of virtually all effective BPH surgeries, not unique to HoLEP.
Temporary urinary incontinence, usually stress-related leakage during coughing or straining, occurs in anywhere from 3% to 26% of patients. The wide range reflects differences in how studies define and measure it. Most men regain full continence within the first year, often within the first few months. Pelvic floor exercises (Kegels) before and after surgery can speed this process.
Erectile function, a major concern for many men considering prostate surgery, does not appear to decline after HoLEP. A study measuring erectile function scores before and after the procedure found no significant change, with scores actually trending slightly higher after surgery. The relief from bothersome urinary symptoms may contribute to that improvement.
Why HoLEP Isn’t More Widely Available
Despite its advantages, HoLEP has a steep learning curve. The enucleation technique requires significant surgical skill and experience, and not all urologists are trained in it. The AUA guidelines acknowledge this directly, noting that “not all providers have access to or are using HoLEP technology.” If your urologist doesn’t perform HoLEP, it’s worth asking for a referral to a center that does, particularly if you have a large prostate or want the shortest recovery time and most durable results available from a single procedure.
