ULTRASOUND DIAGNOSTICS
the balloons of the viCto/viCto+ implant
can be easily visualized using ultrasound.
With
appropriate
settings,
the
outline,
particularly the highlighted top and bottom of
the balloons, can be seen.
the straight line distance between these
highlights will give the diameter of the
balloons. When the cuff is normally inflated
between voidings, the srB and prB should
be very nearly of the same diameter and
pressure.
From the diameter of one of the balloons,
and using the following formula, the added
volume can be determined.
[(4/3π(d/2)³)-9]
With this ultrasound technique it is also
possible to determine the normal functioning
of the device during voiding. pump the
sphincter cuff down with about 2 or 3 good
squeezes and notice the enlargement of
the prB while the srB diminishes in size.
After waiting for approximately 10 to 15
minutes, during which time the cuff will be
fully reinflated, the two balloons should have
returned to approximately the same size.
