Group/Cohort Intervention/treatment
stability of Beacons in prostatic bed
Patients implanted with the Calypso transponders following radical prostatectomy for prostate cancer will be followed for observation of transponder stability.
Other: Observation of transponder stability
Observation of transponder stability and placement in the prostatic bed following radical prostatectomy

Primary Outcome Measures :
