Laser prostate surgery is used when an enlarged prostate blocks urine flow and tablets are not enough, not tolerated or no longer suitable. It may help men who are tired of weak flow, straining, disturbed sleep, repeated retention or catheter dependence. The surgery is done through the urine passage, without an external cut. A laser is used either to remove prostate tissue, as in HoLEP, or vaporise it, as in GreenLight/PVP surgery. The best option depends on prostate size, bladder strength, bleeding risk, PSA evaluation, medicines, catheter status and surgeon experience.

What is laser prostate surgery?

Laser prostate surgery is an endoscopic surgery for benign prostate enlargement, also called BPH (benign prostatic hyperplasia).

The prostate sits below the urinary bladder and surrounds the urethra, which is the urine pipe. As men age, the inner part of the prostate may enlarge and squeeze this pipe. This can make urination slow, incomplete and frustrating.

During laser prostate surgery, a urologist passes a telescope through the penis into the urine passage. A laser fibre is then used to open the blocked channel. There is usually no cut on the abdomen.

This surgery is for non-cancerous prostate enlargement. It is different from radical prostatectomy, which is prostate cancer surgery.

Laser prostate surgery is not one operation

Many patients say, “Doctor, I want laser.” But laser is a tool, not a single operation. The technique matters.

BAUS describes HoLEP as removing obstructing prostate tissue using a laser fibre passed through a telescope, followed by a temporary bladder catheter. GreenLight/PVP creates a wider channel through the prostate and is often associated with less bleeding and earlier discharge than conventional TURP in selected patients.

Who may need laser prostate surgery?

Laser surgery may be considered if enlarged prostate symptoms are affecting daily life and medicines are not enough.

Common reasons include:

• Weak urine stream.
• Straining to pass urine.
• Starting and stopping during urination.
• Feeling that urine remains inside.
• Frequent urination, especially at night.
• Sudden urgency to pass urine.
• Recurrent urine infection.
• Blood in urine due to prostate enlargement.
• Bladder stones.
• Repeated urinary retention.
• Long-term catheter dependence.
• Kidney swelling or kidney function changes due to obstruction.

NICE recommends specialist referral when bothersome urinary symptoms do not respond to conservative measures or medicines, and in complicated cases such as recurrent infection, retention, suspected kidney impairment or suspected cancer.

When is laser surgery better than medicines?

Medicines can work well for many men. Surgery is not needed just because the prostate is enlarged on ultrasound.

Surgery becomes more relevant when:

• Symptoms remain severe despite medicines.
• Medicines cause dizziness, weakness, low BP or sexual side effects.
• The bladder is not emptying well.
• The patient has repeated urinary retention.
• A catheter cannot be removed successfully.
• There are recurrent infections, bladder stones or bleeding.
• Kidney function is affected by obstruction.
• The patient wants a more definitive solution after proper counselling.

NICE advises surgery for voiding symptoms when symptoms are severe, or when medicines and conservative options are unsuccessful or unsuitable.

Who should not rush into laser prostate surgery?

This is important. Laser surgery is useful, but it should not be sold as a shortcut for every urinary problem.

You should not rush into surgery if:

• Symptoms are mild and not affecting quality of life.
• Urine infection is active and not yet treated.
• PSA is high or prostate cancer suspicion has not been evaluated.
• Main symptom is urgency/frequency due to overactive bladder, not obstruction.
• Bladder muscle is very weak and expectations are unrealistic.
• Diabetes, heart disease or blood thinners are not optimised.
• You have not discussed ejaculation changes.
• You are choosing surgery only because “laser sounds advanced.”

A good decision is based on symptoms, prostate anatomy, urine flow, residual urine, PSA context, bladder condition and patient priorities.

How laser prostate surgery is done

Laser prostate surgery is usually done under spinal anaesthesia or general anaesthesia.

The urologist passes a telescope through the urethra. The bladder and prostate channel are inspected. The laser fibre is then used to treat the obstructing prostate tissue.

In HoLEP, the obstructing inner prostate tissue is separated from the outer capsule, pushed into the bladder and removed using a morcellator. The removed tissue can be sent for histopathology testing.

In GreenLight/PVP, the laser vaporises the obstructing tissue layer by layer. This opens the urine passage, but because the tissue is vaporised, there may be little or no tissue available for histopathology. BAUS notes that vaporised prostate tissue is not available for pathology analysis, so cancer-related concerns should be assessed before surgery.

At the end, a urinary catheter is usually placed to drain urine and wash out blood or clots if needed.

HoLEP vs GreenLight: how does a urologist decide?

EAU guidance states that HoLEP has similar mid- to long-term efficacy compared with TURP, with a favourable perioperative profile, and recommends HoLEP for moderate-to-severe LUTS due to benign prostatic obstruction as an alternative to TURP or open prostatectomy.

For GreenLight/PVP, EAU notes shorter catheterisation and hospital stay and lower transfusion rates compared with TURP in studies, while also highlighting that operation time and reoperation risk may favour TURP in some comparisons.

Indian practical angle: what affects the choice?

In India, the “best” surgery is not only a textbook decision. Practical factors matter:

• Prostate size and shape.
• Availability of HoLEP, ThuLEP or GreenLight laser.
• Surgeon’s experience with that exact technique.
• Whether tissue is needed for histopathology.
• Blood thinner or cardiac history.
• Anaesthesia fitness.
• Insurance, PMJAY/private package coverage and hospital policy.
• Ability to return for follow-up and catheter removal.
• Patient priority: faster recovery, durable relief, ejaculation preservation or avoiding repeat surgery.

A well-done bipolar TURP may be better than a poorly selected laser procedure. Similarly, a well-done HoLEP can be excellent for a large prostate. The tool matters, but the decision and execution matter more.

Benefits of laser prostate surgery

Possible benefits include:

• Stronger urine flow.
• Less straining.
• Better bladder emptying.
• Fewer night-time toilet visits over time.
• Catheter removal in many retention patients.
• Less bleeding compared with some older techniques.
• Shorter catheter time and hospital stay in selected patients.
• Useful option for some patients on blood thinners, after careful planning.
• Durable relief, especially with enucleation procedures like HoLEP.

AUA guideline summaries include HoLEP and ThuLEP as prostate size-independent options, depending on surgeon expertise, and PVP as an option using modern 120W or 180W platforms for LUTS/BPH.

Risks and side effects

Laser prostate surgery is generally safe when done for the right patient, but it is still surgery.

Possible risks include:

• Burning while passing urine.
• Frequent urination or urgency during healing.
• Blood in urine.
• Temporary difficulty passing urine after catheter removal.
• Need for temporary re-catheterisation.
• Urinary infection.
• Temporary urine leakage, especially after large tissue removal.
• Retrograde ejaculation, also called dry ejaculation.
• Urethral stricture or bladder neck narrowing.
• Bleeding needing transfusion or re-operation, uncommon but possible.
• Anaesthesia-related heart, lung or clotting risks.
• Symptoms may not fully improve if the bladder muscle is weak.

BAUS lists temporary burning, bleeding and frequent urination as common after HoLEP, and retrograde ejaculation in around 90% of patients. For GreenLight laser, BAUS lists retrograde ejaculation in about 3 to 5 out of 10 patients and urinary infection in about 1 in 20 patients.

Will laser prostate surgery affect sex?

Most BPH surgeries do not usually damage erection nerves directly because those nerves lie outside the prostate capsule. However, age, diabetes, BP, vascular disease and existing erectile dysfunction may affect erections independently.

The more common change is ejaculation. After surgery, semen may go backward into the bladder instead of coming out through the penis. This is called retrograde ejaculation. It is not dangerous, but it can affect fertility and sexual satisfaction.

If fatherhood is still planned, discuss semen preservation or treatment choices before surgery.

Catheter and hospital stay

Typical expectations:

• HoLEP: catheter often 24 to 72 hours.
• GreenLight/PVP: catheter may be removed within 48 to 72 hours; selected patients may go home the same day.
• Large prostate, retention, blood thinners or infection: catheter and stay may be longer.

BAUS notes that after HoLEP, catheter removal is commonly within the first 1 to 2 days, though some men may need a temporary repeat catheter if swelling prevents urination.

Recovery after laser prostate surgery

A useful counselling line is: flow improves first; urgency settles later.

BAUS notes that overactive bladder symptoms such as frequency and urgency can take up to three months to settle, while urine flow often improves earlier.

Tests before laser prostate surgery

A proper decision needs more than ultrasound prostate size.

Useful tests may include:

• Urine routine and microscopy.
• Urine culture, especially if burning, catheter or infection history is present.
• Serum creatinine and kidney function.
• PSA, after appropriate counselling.
• Ultrasound KUB with prostate size and post-void residual urine.
• Uroflowmetry.
• Digital rectal examination.
• Cystoscopy in selected patients.
• ECG, blood tests and anaesthesia fitness.
• Review of diabetes, BP, heart disease and blood thinners.

NICE recommends flow-rate and post-void residual measurement during specialist assessment for men with LUTS, and PSA discussion when symptoms suggest obstruction, prostate examination is abnormal or the patient is concerned about prostate cancer.
