An indwelling urethral catheter sizing system comprises sets of substantially equal length indwelling urethral catheters (14) having various balloon spacings (a, b, c), from bladder balloons (2) to urethral anchoring cuff balloons (36). A method of implanting an indwelling urethral catheter from the sets involves first determining a patient's interballoon urethral segment length, from his bladder to his bulbous urethra immediately downstream of what remains of his prostate gland. A urethral sizing catheter having a balloon spacing corresponding to the interballoon urethral segment length is inserted in the patient to determine the clinical length of the patient's urethral tract from his bladder to his penile meatus. A male indwelling urethral catheter is then chosen from the sets having a balloon spacing corresponding to the patient's interballoon urethral segment length and the clinical length determined with the urethral sizing catheter. The urethral sizing catheter can be used for filling and voiding the bladder.
