Greenlight laser treatment for enlarged prostate

Mr Antony Riddick, consultant urologist, is now offering the Greenlight laser treatment at Spire Cambridge Lea Hospital.

Photoselective Greenlight laser vapourisation is an alternative surgical procedure for treating the enlarged prostate. It is the particular wavelength of the laser light that gives this laser its name and more importantly its unique attributes. The green light of the laser is avidly absorbed by red; the prostate gland has a very good blood supply and may be considered biologically red. The prostate gland, therefore, is an excellent target for the Greenlight laser in achieving vaporisation of tissue.

The laser is able to vaporise prostate tissue, but because of only shallow conduction (or scattering) of the laser beyond the zone of vaporisation, sufficient surrounding coagulation ensures that the procedure is practically bloodless. Vaporisation of the prostate using the Greenlight laser (Photoselective vaporisation of the prostate – PVP) is the only true surgical treatment of the procedure where there is an extremely low risk of heavy bleeding or the need for a blood transfusion.

The evolution of the Greenlight laser over the last 15 years has been based on technology allowing ever higher power delivery, hence more efficient vaporisation. The initial 80 Watt Greenlight PV system was introduced into the UK in 2002. This was then replaced in 2006/7, by the High Performance (Greenlight HPS) 120 Watt system allowing much faster vaporisation of prostate tissue.

The latest Greenlight 180-W XPS laser system using the cleverly designed MoXy laser fibre is twice as efficient as this last model, with more power being delivered to a wider surface area. This system is now available at the Spire Cambridge Lea Hospital. This ensures quicker and more thorough tissue removal, whilst maintaining the unique, exceptional quality of ensuring none or very minimal bleeding during the procedure. Operating times with this latest system are similar to traditional resection (TURP) techniques.

The Operation and Recovery

What kind of anaesthetic?
Greenlight XPS laser vaporisation of the prostate, also known as Photoselective Vapourisation of the Prostate (PVP), may be performed under general or regional local anaesthesia.

How is it done?
The procedure involves the passage of a specialised telescope down the water pipe or urethra and through that, the MoXy laser fibre. Vaporisation of the prostate is then performed under direct vision. This continues until a wide channel is created through the prostate gland. A standard urinary catheter or drainage tube is usually placed down the urethra into the bladder at the end of the procedure. This may be removed either later the same day or the morning after. A major advantage of the technique is the ability to use a smaller, more comfortable catheter compared to other techniques.

How long does it take?
The length of time of vaporisation required and therefore how long the procedure takes is determined by the size of the prostate. The experience of the surgeon not only influences the speed of the procedure but also the volume of tissue removed. Based on current experience the procedure can take between 15 minutes and and just over one hour. Exceptional cases may require a longer procedure.

How long am I in hospital?
Unlike any of the other operations available, Greenlight laser vaporisation of the prostate is the only procedure that can reliably offer a day case option whatever the size of the prostate. Some patients may stay one night in hospital due to unrelated issues or through personal choice.

The Recovery
We encourage an unrestricted return to normal activities as quickly as patient confidence allows. The timing of this may vary from patient to patient. It is probably best to avoid any exertion, heavy lifting, straining etc for a week or so after the operation. This includes sexual activity.

There may be some discomfort or burning when passing urine in the first day or two, and this may continue at a low level for a bit longer, usually settling within the first three weeks. Similarly, although the procedure itself is virtually bloodless, it is not that unusual to see some blood in the urine on and off over the first few weeks. This is normal.

In the early phase following the procedure, the first positive changes will be in the strength of the urine stream. Improvements in other urinary symptoms, such as getting up at night to pass urine, going frequently during the day, inability to hold on etc, may take longer to be seen and can vary between days, weeks or even months to get as good as they are going to be.

The enemy of any surgery is infection and an infection in the urine after this surgery may mean a slower pattern of recovery all-round. Symptoms such as ongoing or worsening burning on passing urine, feeling unwell or high temperatures require early consultation with your surgeon or GP.

Who is suitable for Greenlight laser surgery?
All men with symptoms that relate to the obstruction of outflow of urine from the bladder because of prostate disease are suitable for this kind of surgery and even if they have had surgery before.

Compared to all other surgical options, Greenlight laser surgery has advantages in terms of:

For younger men
- A short hospital stay
- A rapid return to normal activities, including work
- The least risk of impact on sexual function

For older men
- A short hospital stay
- A rapid return to normal activities
- A zero risk of heavy blood loss and the need for blood transfusion, whatever the size of the prostate
- An exceptional safety profile for those with other medical conditions.

For men taking antiplatelet or anticoagulant therapy, eg aspirin, clopidogril, warfarin, Greenlight laser surgery has a proven safety profile that no other prostate surgery can offer. Unlike TURP, these medications can continue avoiding the proven small risk in cardiovascular complications after surgery, including strokes and heart attacks that occur on stopping these medications.

About Mr Tony Riddick
Mr Antony Riddick Urology Consultant, Cambridge, private hospital specialist.
I graduated from Nottingham University in 1992. My initial general surgical training was based in Sheffield and Nottingham. My specialist urological training was based in East Anglia (Addenbrookes, Cambridge, Norwich and Ipswich).

During this time I was trained in all aspects of urology and specifically in uro-oncology and laparoscopic surgery. I also had specific research training in molecular oncology resulting in the award of an MD degree.

In 2005 I was appointed to a consultant urologist post in Edinburgh, working for NHS Lothian. During this time I developed a specialist tertiary renal cancer service, offering a comprehensive renal cancer surgical service. In parallel I developed a research program in renal cancer establishing an NHS Lothian renal cancer tissue bank followed by the SCOTTRCC, the Scottish national kidney cancer biobank. I also developed my interest in prostatic disease, developing a diagnostic prostate cancer service in Livingston and day case 180W Moxy fibre photoselective vapourisation of the prostate, performing the first cases in Scotland and establishing an extensive personal experience including mentorship of consultants in external units. I have a keen interest in education and was training program director for the East of Scotland Urology for five years and I remain on the faculty for BAUS courses including laparoscopy and Greenlight laser prostatectomy. I moved to Addenbrookes Hospital in July 2013.
