Selective Vaporization Of Prostate)
What is a Photoselective
Vaporization of Prostate (PVP)?
Photoselective vaporization of the
prostate (PVP) is a form of laser therapy used to
remove all or part of the prostate gland. It is used
to treat benign prostatic hyperplasia (BPH), a non-cancerous
growth or enlargement of the prostate gland.
How is it done?
PVP is performed under local, spinal
or general anesthesia and takes between 20 and 50
minutes. A very large prostate may take longer time.
During the procedure, the surgeon will use tube called
an endoscope to deliver the laser to the prostate
vaporizing any excess tissue. Some patients will be
required to be catheterized for up to 24 hours after
Why is it done?
PVP is recommended for patients
who have urination symptoms resulting from benign prostatic
enlargement such as inability to urinate; bleeding
through the urethra; kidney damage caused by urine
backing up; frequent urinary tract infections; or
stones in the bladder. For symptoms like :- poor urination,
frequency of urination , night time urination more
than two times/night , the doctor will consider if
the severity of the symptoms warrants surgery or not.
Risks & complications
Complications are infrequent and
usually minor. There are possible risks and complications
associated with anesthesia, including respiratory
or cardiac malfunction. Other complications include
the possibility of:
- Small amount of blood in urine
- Mild irritation or urinary frequency for short
period of time
- Emptying of semen into the bladder instead of
out of the urethra (called retrograde ejaculation,
or 'dry' orgasm)
Some patients may experience
bleeding and blood in the urine for several weeks
after surgery. Risks can be reduced by following the
surgeon's instructions before and after surgery.
The surgeon may discuss alternative
approaches to PVP laser treatment. Some medicines
can improve the flow of urine or shrink the prostate.
A short tube (called a stent) can be inserted into
the urethra to improve urine flow. Saw palmetto extract
is one of several herbal remedies that may be helpful.
Heat therapy using microwaves, ultrasound or electric
current instead of lasers can be used to destroy excess
prostate tissue. If symptoms are not troublesome,
some men choose not to have any treatment. Symptoms
do not always worsen over time and can sometimes improve
The best candidates for Photoselective
Vaporization of Prostate (PVP) are men with moderate
to severe symptoms (i.e., bladder obstruction) caused
by prostate enlargement either or not responded to
proactive medical therapies. Patients with prostates
of a combined volume of more than approximately 250cm3
may not be candidates for PVP or other transurethral
procedures. More invasive surgical techniques may
be required. The urologist will make the final determination
of each patient's eligibility for the procedure after
an examination and consultation with the patient.
