CLASSICAL INTERSTITIAL TECHNIQUES
DRAWBACKS
Accurate freehand implantation is difficult
-
operator-depedent
-positioning often inaccurate
-loss of parallelism
-not reproducible
Perineal templates (Syed, MUPIT, others)
- high number of needles used
- long distances between template and target (loss
of parallelism, inaccurate positioning)
- impediment for general acceptance:
considerable risk of serious acute/late complications
