{"groups":[{"description":"This study will enroll patients that have a confirmed histology of prostate cancer. They will undergo a 3T MRI scan as well as a CT simulation with 16 French Foley Catheter containing dummy beacons for treatment planning purposes. The patient will then receive focal stereotactic body radiotherapy (SBRT) at a dose of 40 gy in 5 total fractions. Patients will be followed for 24 total months with specific follow-ups at 3, 6, 9, 12, 18, and 24 months.\n\n16 French Foley Catheter: A Foley catheter is a medical apparatus that creates a passageway for the drainage and collection of urine. This type of catheter is made of a pliable material that indwells into an individual's bladder by way of the urethra.\n\nFeaturing two separate channels down the tube, Foley catheters allow absolute stability and safe extraction. One channel of the catheter, by method of a balloon, is stabilized in a bladder; the other channel allows for the passage and collection of urine, by means of a leg bag or bedside drainage bag.\n\nFoley catheters are usually constructed out of either silicone or latex.","id":"FG000","title":"Focal SBRT With Intra-urethral Radiotransponder"}],"periods":[{"dropWithdraws":[{"reasons":[{"groupId":"FG000","numSubjects":"1"}],"type":"Withdrawal by Subject"}],"milestones":[{"achievements":[{"groupId":"FG000","numSubjects":"5"}],"type":"STARTED"},{"achievements":[{"groupId":"FG000","numSubjects":"4"}],"type":"COMPLETED"},{"achievements":[{"groupId":"FG000","numSubjects":"1"}],"type":"NOT COMPLETED"}],"title":"Overall Study"}]}
