What Is InterStim Therapy?
InterStim Therapy is indicated for people
with urinary retention and the symptoms of overactive
bladder including urinary urge incontinence and significant
symptoms of urgency-frequency in selected individuals.
The therapy uses a small implanted medical device
to send mild electrical pulses to a nerve located
just above the tailbone. This nerve, called the sacral
nerve, controls the bladder and surrounding muscles
that manage urinary function. The electrical stimulation
may eliminate or reduce certain bladder control symptoms
in some people.
How Will I know If InterStim Therapy Will
Work for Me?
A physician’s examination and evaluation
can determine whether you are a candidate for InterStim
Therapy. If your bladder control problems are not
effectively managed by more conservative treatments
and you have otherwise normally functioning urinary
systems, you are a potential candidate.
A test (the temporary test stimulation) is used before
implantation of the therapy to see what the effect
of stimulation is on your symptoms. A test lead is
surgical placed through a small incision near the
appropriate sacral nerve, and mild stimulation with
an external device is provided for several days. During
the test stimulation, you will record your symptoms
in a special diary. If symptoms improve or disappear
during the test period, long-term use of InterStim
Therapy may be appropriate for you.
What Does the Therapy Involve?
A lead (a think wire with small electrodes
at its tip) is surgically placed near the appropriate
sacral nerve that controls urinary function. The lead
is passed under the skin to a small neurostimulator
(approximately the size of a stopwatch) that is placed
in a “pocket” just beneath the skin.
The neurostimulator, which contains a special battery
and electronics to control the stimulation to the
sacral nerve, is usually placed by the physician in
the upper buttock or lower abdomen.
The stimulator typically runs for 7-9 years and then
can be replaced running an outpatient procedure.
Adjustments to the stimulation can be made in a physician’s
office with a hand-held programmer. InterStim Therapy
is reversible – it can be programmed off at
any time.
What Are the Potential Benefits of InterStim
Therapy?
InterStim Therapy may eliminate or reduce
symptoms caused by bladder control problems.
