Determining Median Lobe Treatment

MA07445A008 Rev X
Treatment regions of the median lobe may be described as upper,
middle, and lower. If the prostate median lobe is unusually long,
then additional sites more distal to the bladder may be treated.
Treatment locations (10, 12, and 2 o'clock) are recommended for
the proximal (upper) end of the median lobe (Figure 4-4). The
6 o'clock location is for treatment at the distal (lower) end of the
median lobe. The number of lesions typically is based on the size
of the median lobe (Table 4-3).
When treating the median lobe it is necessary to visualize its size
and structure. The needles of the catheter should be deployed
1 cm away from the proximal margin of the bladder neck. Advance
down the median lobe under direct vision as necessary.
It is recommended that selecting a needle length of 12 or 14 mm
is sufficient for treatment of the median lobe.
The determination of median lobe treatment locations and
appropriate needle lengths is the clinician's sole medical
judgement.
