A SIMPLE METHOD TO STABILIZE THE PROSTATE DURING TRANSPERINEAL PROSTATE BRACHYTHERAPY

Purpose: The authors report a simple, remarkably effective method to l imit prostatic motion during prostate brachytherapy. Methods and Mater ials: Two 18-ga. stainless-steel needles (the same type used for sourc e placement) are inserted transperineally, obliquely into the prostate , using finger and fluoroscopic guidance, These needles are left in pl ace during the implant procedure, In our experience, maximum lateral d isplacement is decreased from about 1 cm to 0.2 mm, while craniocaudal motion is virtually eliminated. Conclusion: The method described here is simple to perform and does not require specialized equipment. (C) 1997 Elsevier Science Inc.
