Minimal displacement of novel self-anchoring catheters suitable for temporary prostate implants

Catheters were developed that can be fixed in the prostate gland by self-expanding parts for use in PDR brachytherapy. Daily CT-scans were made to investigate the magnitude of catheter displacement.The mean absolute displacement during the 3 day treatment was 1.2 mm. The resulting minor alterations in dose–volume parameters were of no clinical importance.
