RAD 1801: Pilot Study of Intra-Urethral Radiotransponder Beacon Guided Focal Prostate Stereotactic Body Radiotherapy

"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.~Featuring 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.~Foley catheters are usually constructed out of either silicone or latex."
