HoLEP: Holmium Laser Enucleation of the Prostate – Modern Treatment Standard

What is Prostate Adenoma and Why Does It Require Treatment?

Benign prostatic hyperplasia (BPH), or prostate adenoma, is an extremely common condition among older men, affecting nearly 80% of men over the age of 70 [6]. This condition is characterized by an enlargement of the prostate, which compresses the urethra, causing a range of unpleasant symptoms known as lower urinary tract symptoms (LUTS). These include frequent urination, weak stream, nighttime urination (nocturia), a feeling of incomplete bladder emptying, and sudden urges. These symptoms significantly reduce quality of life and, if left untreated, can lead to serious complications such as urinary tract infections, bladder stones, and renal failure.

The Evolution of Prostate Adenoma Treatment: From TURP to Laser Technologies

For many years, transurethral resection of the prostate (TURP) was considered the "gold standard" for the surgical treatment of BPH [6]. However, with the advancement of medical technologies, a deeper understanding of laser-prostate tissue interactions, and the accumulation of clinical experience, new, less invasive treatment methods have emerged [1]. Various types of lasers have been introduced, including neodymium:yttrium-aluminum-garnet (Nd:YAG), holmium (Ho):YAG, potassium-titanyl-phosphate (KTP):YAG, thulium (Tm), and diode lasers [1]. These lasers allow for various surgical techniques: coagulation (which has been largely abandoned), vaporization, resection, and enucleation [1]. Among them, holmium laser enucleation of the prostate (HoLEP) has become the leading technique, challenging and ultimately surpassing TURP [1, 6].

HoLEP: The Gold Standard for Laser Enucleation of the Prostate Adenoma

HoLEP (Holmium Laser Enucleation of the Prostate) uses a holmium (Ho):YAG laser to precisely "shell out" or remove enlarged adenomatous prostate tissue [1]. This technique is performed endoscopically, meaning there are no external incisions. The surgeon inserts a thin instrument through the urethra to reach the prostate. Current literature indicates that HoLEP has replaced TURP and even open simple prostatectomy as the surgical "gold standard" for the treatment of BPH, regardless of prostate size [6]. This means it is effective for prostates of virtually any volume. The procedure involves separating the adenoma from the prostate capsule, similar to an open prostatectomy, but using a minimally invasive approach. The removed tissue is then pulverized (morcellated) and aspirated [6].

• High Efficacy: HoLEP ensures the complete removal of obstructive tissue, leading to significant and long-term improvement in lower urinary tract symptoms [6].
• Minimal Blood Loss: The laser coagulates vessels during enucleation, reducing the risk of bleeding compared to TURP and open surgery [1, 6].
• Safety for Patients on Anticoagulants: Due to the reduced risk of bleeding, HoLEP is the preferred option for men taking anticoagulant medications [1].
• Long-term Results: Studies confirm the high durability of HoLEP results, with a low risk of reintervention [6].
• Rapid Recovery: Patients are typically discharged from the hospital earlier and return to normal activities faster [6].

How is the HoLEP Procedure Performed?

HoLEP surgery is performed under general or spinal anesthesia. The urologist inserts a thin endoscope through the urethra into the bladder. Using a fiber-optic laser, the surgeon gently separates (enucleates) the enlarged adenoma tissue from the healthy prostate capsule. This process allows the entire adenoma to be removed, rather than just a part of it, as in TURP [6]. The separated tissue is then moved into the bladder. A special instrument called a morcellator is inserted through the same endoscope to grind the removed tissue into small fragments, which are then aspirated and removed from the body [6]. This provides tissue samples for histological examination to rule out malignant changes.

HoLEP Compared to Other Methods and Potential Risks

Comparison with TURP and Open Prostatectomy: HoLEP demonstrates superiority over traditional methods, offering similar or better efficacy with lower invasiveness and risks [6].

Other Laser Methods: Although other laser technologies exist for the treatment of BPH (e.g., thulium laser enucleation or vaporization), HoLEP has the most extensive evidence base supporting its results [1, 6].

Aquablation: It is worth noting that there are other innovative approaches, such as aquablation, which uses a high-velocity water jet to remove prostate tissue. The WATER II study showed that aquablation is effective for prostates with a volume of 80-150 ml, with an average operative time of 37 minutes [5]. This highlights the variety of modern minimally invasive solutions for BPH.

Potential Risks and Side Effects:

• Like any surgical procedure, HoLEP carries certain risks, including bleeding, infection, and temporary urination problems [6].
• Ejaculatory Dysfunction: This is a common complication after BPH surgeries. A systematic review showed that while ejaculatory dysfunction is frequent, standardized data to counsel men wishing to preserve ejaculation are insufficient [2]. It is important to discuss this aspect with your urologist before surgery.
• Adverse events associated with the HoLEP procedure, including the enucleation and morcellation phases, are thoroughly studied, and their frequency is considered low [6].

Who is HoLEP Surgery Indicated For?

HoLEP is an excellent choice for men suffering from moderate to severe lower urinary tract symptoms caused by benign prostatic hyperplasia [6]. It is particularly recommended for:

• Patients with large-volume prostates for whom TURP may be less effective or riskier [6].
• Men taking anticoagulants (blood thinners) because HoLEP is associated with less blood loss [1].
• Patients with acute urinary retention [1].
• Those seeking a long-term solution with a low risk of reintervention [6].
