Determining Number of Treatment Planes

The following table (Table 4-2) provides guidelines for determining
the number of treatment planes based on the distance from the
bladder neck to the verumontanum. Ideally, a minimum of two
planes should be treated providing that the distance from the
needle placement to the bladder neck and from the needle
placement to the verumontanum remains 0.75-1.0 cm.
A treatment plane consists of delivery of energy to the right and
left lobes at the same level as shown in Figure 4-3.
Note: For each additional centimeter in length, add an additional
treatment plane.
The determination of the number of treatment planes is in the
clinician's sole medical judgment.
