Green Light Laser Prostatectomy
GreenLight laser prostatectomy is an operation that uses a laser to remove excess tissue in the central part of your prostate gland. The laser uses concentrated light to generate precise and intense heat which vapourises the tissue. The procedure is also known as photo-selective vaporisation of the prostate (PVP).
You usually have this procedure if you have benign (non-cancerous) swelling of your prostate gland. This presses against your urethra (the tube that drains urine from your body) and leads to symptoms such as making it difficult for you to urinate. The procedure can also be used to ease the blockage caused by prostate cancer. We do not take out the whole prostate but remove the central part of your prostate gland, which should enable you to urinate normally.
A telescopic instrument called a cystoscope is passed into your urethra (the tube through which you pass urine) and up into your bladder to enable it to be examined. The cystoscope is about the thickness of a pencil and has a tiny video camera on one end, enabling images of your bladder to be viewed on a television screen. The prostate tissue is vaporised through the cystoscope using a high-powered laser. A small catheter may be placed in your urethra to drain urine if we have any concerns about whether your bladder will work normally for the first 24 hours after your procedure.
It is a minimally invasive procedure taking only between 45 – 60 minutes. You will not have any cuts or stitches. Most men have it as a day case procedure – only a small number of patients need to stay in hospital overnight.
