Page Background




An average GP practice with 2000 patients will have approximately

150 men registered with urinary symptoms severe enough to

consider seeking treatment at some point in time.

Traditionally, the successful management of

symptomatic Benign Prostatic Hypertrophy

(BPH) has beenTransurethral Resection of

the Prostate (TURP), which was viewed by

both surgeons and General Practitioners as

the gold standard procedure, given its proven

efficiency and long-term durability.

When the GreenLight PVP laser therapy

was introduced to the UK five years ago

by Consultant Urological Surgeon, Mr

Gordon Muir, the laser technique not only

demonstrated comparable advantages to

those of TURP, but also highlighted the

unique benefits of being a daycase, with

reduced blood loss, few complications

(if any) and minimal morbidity.

In 2004, the GreenLight laser procedure

at King’s College Hospital received the UK

Clinical Excellence Award for Innovation,

soon followed by the approval of the

National Institute for Health and Clinical

Excellence (NICE).Today, more than 1000

urologists over 30 countries, (many trained

by Mr Muir), perform the minimal invasive

operation and over 150,000 patients have

successfully been treated.

In January this year, Executive Director, John

Reay, decided to equip the hospital with the

most advanced model of the GreenLight, the

GreenLight HPS, with a view to providing his

patients with a laser surgical alternative to

TURP, that had proven comparable benefits.

Mr Gordon Muir, who has performed over

1000 GreenLight operations and who was

the first surgeon in Europe to use the HPS,

confirmed over 95% success rate in men with

catheters for retention of urine, thanks to the

new technology and reported overall excellent

results from a surgical perspective, coupled

with very positive patient feedback.

Mr Muir also observed that the HPS definitely

sped up the process of removing obstructing

prostate tissue, allowed more precision when

compared with its predecessor, reduced time

under anaesthesia and, ultimately, increased

safety for patients.

What is the GreenLight laser?

The GreenLight PVP technology releases

high powered laser energy into the cells by

means of continuous saline irrigation, which

is then absorbed by tissue and haemoglobin,

leading to a rapid heating of cells and

vaporisation of tissue.

Similarities withTURP

• Greater than 100% improvement in urinary

flow rates

• Over 50% decrease in symptoms

• Spontaneous voiding for patients with

urinary retention

• Immediate removal of the prostatic bladder

outlet obstruction

• Comparable operative time

• Proven capability

Long-term durability

Observations of the GreenLight PVP during

clinical studies concluded to the durable

capability of the procedure and its long-term

outcomes, with significant improvements in

maximum urinary flow rate. 4-5 year follow-

up from a number of International centres,

including ours, suggests positive durable results.

Advantages over TURP

Clinical studies have shown a low risk of

mainly minor adverse events.TURP can be

accompanied by risks of postoperative urinary

retention, infection, incontinence, erectile

dysfunction, impotence, blood transfusion,

capsular perforation, clot retention.

With the GreenLight laser therapy, the risks

of serious bleeding,TUR Syndrome and

erectile dysfunction are close to nil. Economic

studies have highlighted the benefits of the

GreenLight, in terms of in-hospital costs, and

mostly, patients are able to return to normal

activity very rapidly.

Large Prostates

Traditionally, open prostatectomy was the

operation of choice for patients with large

prostates, due to the relative inability of

TURP to resect larger glands over 80-100ml

due to the risks of TUR Syndrome and

severe bleeding. Since then, the GreenLight

laser therapy has proved to be a very safe

option in treating these large prostates, and

many of these patients can even be treated

in a daycase setting.

TUR Syndrome

TURP carries a significant risk of absorbing

the irrigating fluid that may cause pulmonary

and cerebral oedema, in extreme cases

leading to ITU treatment. Our research on

the GreenLight laser has shown that this

potential complication is abolished.

High Risk Patients

For patients on anticoagulant therapies, with

bleeding disorders or at risk of cardiovascular

co-morbidity, the GreenLight laser procedure

offers a reasonable surgical alternative due to

its haemostatic nature, significantly decreasing

the risks of bleeding, clot retention, transfusion,

sometimes seen withTURP.

Patient Benefits

• Immediate symptom relief

• Rapid flow rate improvement

• Fast recovery times

• Daycase procedure with some

patients resuming work the

following day
