    When a man is diagnosed with a significantly enlarged prostate — typically over 80 to 100 grams — the standard medical treatments often become insufficient. Medications like tamsulosin or finasteride may provide partial relief, but for men with severe lower urinary tract symptoms (LUTS), surgical intervention offers the most durable and effective solution.

    Two procedures stand out as the leading surgical options for very large prostates: Holmium Laser Enucleation of the Prostate (HoLEP) and Robotic Simple Prostatectomy. Both are considered gold-standard treatments, but they differ significantly in their approach, recovery profile, and suitability for individual patients.

    Understanding the Problem: Why Large Prostates Need Surgery

    Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting older men. As the prostate enlarges, it progressively compresses the urethra and obstructs the bladder outlet, leading to symptoms such as a weak urinary stream, frequent urination (especially at night), incomplete bladder emptying, and in severe cases, urinary retention requiring catheterisation.

    For prostates larger than 80–100 grams, less invasive procedures like UroLift, Rezum, or even standard TURP become less effective or technically limited. This is where HoLEP and Robotic Simple Prostatectomy excel — both are designed to remove the obstructing adenoma completely, regardless of gland size.

    HoLEP: The Endoscopic Gold Standard

    HoLEP is a minimally invasive, endoscopic procedure performed entirely through the urethra — meaning no external incisions are required. Using a holmium laser, the surgeon enucleates (shells out) the enlarged prostate tissue from its capsule, much like scooping the flesh from an orange peel. The removed tissue is then morcellated (cut into smaller pieces) within the bladder and extracted.

    Key Advantages of HoLEP

    • No external incisions — the entire procedure is performed through the urethra
    • Minimal blood loss — the holmium laser provides excellent haemostasis
    • Short hospital stay — many patients are discharged on the same day (Day Case HoLEP)
    • Suitable for any prostate size — there is no upper limit on gland size
    • Tissue available for pathology — the removed tissue can be examined to exclude incidental prostate cancer
    • Very low retreatment rate — less than 2% at 10 years
    • Safe for patients on blood thinners — excellent haemostatic properties

    Considerations with HoLEP

    • Requires specialised training and expertise — outcomes are highly operator-dependent
    • Temporary stress urinary incontinence may occur in the early post-operative period (typically resolves within weeks)
    • Retrograde ejaculation occurs in the majority of patients
    • The learning curve is steeper compared to other BPH procedures

    Robotic Simple Prostatectomy: The Robotic-Assisted Approach

    Robotic Simple Prostatectomy is the modern evolution of the traditional open simple prostatectomy. Using the da Vinci robotic surgical system, the surgeon makes several small keyhole incisions in the abdomen to access the prostate. The enlarged adenoma is then enucleated from within the prostate capsule under magnified 3D vision with wristed robotic instruments.

    Key Advantages of Robotic Simple Prostatectomy

    • Excellent visualisation — the robotic system provides magnified, high-definition 3D vision
    • Precise tissue removal — wristed instruments allow meticulous dissection
    • Particularly effective for very large prostates — ideal for glands over 150–200 grams
    • Complete adenoma removal — the direct approach ensures thorough tissue extraction
    • Tissue available for pathology — the entire adenoma specimen is preserved
    • Lower retreatment rate — comparable to HoLEP for long-term durability

    Considerations with Robotic Simple Prostatectomy

    • Requires abdominal incisions (typically 4–5 small keyhole ports)
    • Longer hospital stay compared to HoLEP — typically 1–2 nights
    • Higher blood loss compared to HoLEP, though significantly less than open surgery
    • Catheter duration is typically longer (5–7 days)
    • Retrograde ejaculation occurs in the majority of patients

    Which Procedure Is Right for You?

    The choice between HoLEP and Robotic Simple Prostatectomy depends on several factors unique to each patient:

    • Prostate size: Both handle large prostates well, but Robotic Simple Prostatectomy may be preferred for extremely large glands (>200g) where the adenoma is very bulky.
    • Recovery priorities: If rapid return to normal activities is a priority, HoLEP offers a faster recovery with same-day discharge and shorter catheter time.
    • Blood thinner use: HoLEP's superior haemostatic properties make it the preferred option for men who cannot safely stop anticoagulant medications.
    • Previous abdominal surgery: Men with extensive prior abdominal surgery may be better suited to HoLEP, which avoids the abdominal approach entirely.
    • Surgeon expertise: Both procedures are highly technique-dependent. The best outcomes are achieved by surgeons experienced in the specific procedure.

    Dr Dias' Approach

    Dr Brendan Dias is experienced in both HoLEP and robotic urological surgery, having pioneered Day Case HoLEP at Western Health. He offers both procedures and will recommend the most appropriate option based on your prostate size, symptoms, medical history, and personal preferences.

    During your consultation, Dr Dias will perform a thorough assessment including symptom questionnaires, urine flow studies, ultrasound measurement of prostate volume, and review of any prior investigations. This comprehensive evaluation ensures you receive a tailored recommendation rather than a one-size-fits-all approach.

    Frequently Asked Questions

    Which procedure is better for very large prostates over 150g?

    Both HoLEP and Robotic Simple Prostatectomy are effective for very large prostates. HoLEP can treat any prostate size endoscopically, while Robotic Simple Prostatectomy may be preferred for prostates over 200g where the larger working space and direct vision offer advantages.

    Is one procedure safer than the other?

    Both procedures have excellent safety profiles. HoLEP generally has less blood loss and shorter hospital stays. Robotic Simple Prostatectomy offers precise tissue removal with robotic-assisted vision. The choice depends on individual patient factors and surgeon expertise.

    What about sexual function after either procedure?

    Both procedures preserve erectile function in most patients. Retrograde ejaculation occurs commonly with both HoLEP and Robotic Simple Prostatectomy. Dr Dias will discuss your specific concerns and risks during your consultation.

    The Bottom Line

    Both HoLEP and Robotic Simple Prostatectomy are excellent, durable surgical options for men with large prostates causing significant urinary symptoms. HoLEP offers the advantage of no incisions, faster recovery, and same-day discharge, while Robotic Simple Prostatectomy provides superb visualisation and precision for very large glands. The best choice depends on your individual circumstances — and the most important step is consulting with an experienced surgeon who can offer both options and guide you to the right decision.
