GREEN LIGHT LASER TRANSURETHRAL RESECTION OF PROSTATE
WHAT IS IT?
Green Light Laser Therapy uses a laser to remove obstructing prostate tissue. The laser treatment is delivered through a thin, flexible fiber, which is inserted into the urethra through an instrument called a cystoscope. The fiber carries laser energy which quickly removes prostate tissue. The tissue removal will allow urine to pass through freely. Natural urine flow is rapidly restored and urinary symptoms are quickly relieved in most patients.
Fig. 1 Urinary passage is widened by vaporisation of the prostate tissue with laser.
WHAT TO EXPECT BEFORE SURGERY?
Pre-operative assessments, including blood tests, electrocardiogram, chest x-ray and others, are needed to prepare you before anaesthesia and surgery.
PREPARATION FOR THE SURGERY
THE SURGERY
This operation is done internally with no open wounds.
Under general or spinal anaesthesia, a laser fibre is passed down a cystoscope with a camera and the obstructing prostate tissue is vaporised. This opens up the passageway for the urine to flow through.
After the surgery, a catheter is placed overnight and removed before discharge.

WHAT ARE THE POSSIBLE COMPLICATIONS?
BLEEDING: Most of our patients do not need transfusion during the surgery. Risk of transfusion <4%.
INFECTION: All our patients receive intravenous antibiotics before the operation to reduce the risks of infection (<4%).
RETROGRADE EJACULATION: The bladder neck is widened and causes semen to flow into the bladder, hence resulting in a dry ejaculate and decreased fertility in 70% of men.
INCONTINENCE: Incontinence is rare (<1%).
ERECTION: Erection after this operation is rare(<1%).
STRICTURE: Urinary passage may rarely be narrowed (<1%)
WHAT TO EXPECT AFTER SURGERY?
POST OPERATIVE PAIN: Most patients do not feel pain from the surgery. The catheter may cause a sensation of urgency.
URINARY CATHETER: A urinary catheter draining your bladder is left in place for about 1-2 days.
BLOOD IN THE URINE: This is expected in the first few days after surgery. Occasionally, some patients develop blood clots after surgery. If this happens, please inform the clinic.
DIET: Most patients are able to tolerate liquids the same day and can start on a normal diet the next day.
AMBULATION: We encourage our patients to get out of bed the day after surgery to help prevent blood clots from forming in your legs.
WHAT TO EXPECT AFTER DISCHARGE FROM THE HOSPITAL?
PERSONAL HYGIENE: There is no restriction on showers. There are no stitches to remove.
ACTIVITY: We encourage our patients to take daily walks. Prolonged sitting or lying should be avoided as this can increase your risk of blood clots forming in the leg veins and chest infection. You should avoid driving for at least 2 weeks after surgery. Heavy lifting or strenuous exercising is not advisable for 6 weeks.
DIET: While there is no specific restriction, we do encourage our patients to drink plenty of fluids.
MEDICATIONS: You can resume your usual medications after surgery except antiplatelet or anticoagulant (aspirin or other blood thinners).
HISTOLOGY RESULTS: The histology results are usually available within 2 weeks after surgery.
HOW SOON WILL THE URINARY SYSTEM IMPROVE?
There is usually an immediate improvement in the urine flow. Further improvement may continue up to 6 months. However, you may still pass urine frequently for 2-3 months. Some patients may not be able to empty their bladder completely because of bladder weakness. They may require a longer period of catheter use until their bladder recovers.
